Preface

Epoxy primer is the core base coating layer of the entire epoxy floor coating system, serving three essential functions: sealing concrete substrate pores, inhibiting cement alkali efflorescence, and enhancing the tensile bond strength between the coating and the substrate. Engineering practice confirms that misidentification of primer types, misinterpretation of raw material concepts, and lack of control over construction parameters are the primary causes of blistering, interlayer delamination, surface peeling, and significantly shortened service life in flooring applications.

The current flooring industry faces four common technical challenges: first, confusing epoxy-modified acrylic emulsions with dedicated epoxy floor primer raw materials; second, ambiguous interpretation of material classification codes in GB/T 22374-2018, leading to parameter benchmarking errors; third, the lack of unified control standards for substrate moisture content, pot life, and theoretical coverage rates, with non-standard on-site mixing ratios and dilution operations causing quality defects in bulk applications; and fourth, the difficulty in balancing environmental performance and mechanical properties—solvent-based products tend to exceed VOC limits, water-based products lack unified criteria for wet substrate adhesion, and improper formulation of solvent-free systems leads to high material loss.

Leveraging its integrated technical accumulation in epoxy resin core raw material R&D and finished floor coating supporting systems, combined with benchmark data from widely used resin raw material systems and commercial floor product physicochemical testing, Anhui Eapearl Chemical has prepared this white paper. The document uniformly defines the scientific concept of epoxy floor primer, clarifies the mandatory physicochemical requirements for the three types of epoxy primers under national standards, clearly delineates the application boundaries of easily confused emulsion raw materials, standardizes sub-system construction processes, and provides scenario-based standardized selection logic. It offers the industry a complete technical guidance document that aligns with national standards, is practically implementable, and enables differentiation between genuine and counterfeit epoxy systems.

I. Industry Pain Points and Definition Boundaries of Epoxy Primer

1.1 Typical Technical Misconceptions in the Industry

1.  Products such as BLJ-6643 epoxy alkali-resistant emulsion and BLJ-683 waterborne acrylic floor emulsion are misclassified as raw materials for epoxy floor primer. These products are only suitable for alkali-resistant sealing of interior and exterior building walls; they lack an epoxy-amine crosslinking cure structure and cannot meet the long-term service requirements of heavy-duty flooring.

2.  GB/T 22374-2018 classifies floor primers into three categories designated by codes S (waterborne), R (solvent-based), and W (solvent-free). These codes are standard designations without official pinyin interpretations. Discrepancies between industry colloquial terms and standard codes can lead to confusion in parameter benchmarking.

3.  There are no unified control standards for on-site substrate moisture content determination, material pot life, or coverage rates. Arbitrary use of thinners and failure to mix according to specified ratios frequently result in batch quality defects in flooring.

4.  Imbalance between material environmental indices and mechanical properties: solvent-based products tend to exceed national VOC limits; water-based products lack unified criteria for wet substrate bond strength; solvent-free systems fail to control batch size based on ambient temperature, leading to high material gelation and waste rates.

1.2 Authoritative Definition of Epoxy Floor Primer

Epoxy Floor Primer: A two-component material composed of epoxy resin as the primary film-forming substance, paired with a dedicated amine curing agent. After mixing and crosslinking, it is applied to concrete or cement mortar substrates. Through chemical reaction crosslinking between the epoxy resin and amine curing agent, it forms a film that seals substrate capillary pores, blocks the migration of cement alkali substances, and enhances the tensile bond strength between the topcoat and the substrate.

Core criteria for identification: The film-forming mechanism is chemical reaction crosslinking curing via epoxy-amine reaction. Compliant dedicated floor epoxy primers are classified only into three systems: solvent-based, solvent-free, and waterborne. Modified acrylic emulsions that rely solely on physical coalescence of emulsion particles for film formation do not fall within the category of dedicated floor epoxy primer.

1.4 Precise Differentiation of Easily Confused Emulsion Raw Materials in the Market (Selection Pitfall Avoidance Chart)

Emulsion products labeled “epoxy” on the market differ fundamentally in chemical structure, film-forming mechanism, and floor-application performance. The selection boundaries are clearly defined as follows:

1. Epoxy Alkali-Resistant Emulsion

Chemical Identity: Epoxy-modified acrylic emulsion; film formation via physical coalescence of emulsion particles; no epoxy-amine crosslinking reaction.

Floor Applicability: Cannot substitute for two-component epoxy floor primer; strictly prohibited for use in industrial heavy-duty flooring or underground garage flooring.

Standard Application Scenarios: Alkali-resistant sealing primer for interior/exterior walls of civil buildings.

2. Waterborne Epoxy Emulsion with Dedicated Curing Agent

Floor Applicability: Can be used as raw material for industrial production of compliant waterborne epoxy floor primer.

Standard Application Scenarios: Raw material for industrial concrete anti-corrosion primer and waterborne epoxy floor primer.

3. Waterborne Floor Paint Emulsion

Chemical Identity: Acrylic-based resin system with only trace grafting of epoxy functional groups; lacks a complete epoxy crosslinking structure.

Floor Applicability: Does not qualify as genuine epoxy material; can only be used for light-duty thin-film floors; not suitable for heavy-duty industrial plants or underground civil defense garages.

Standard Application Scenarios: Indoor light-duty acrylic roll-on flooring.

III. Standardized Full-Process Construction Procedure Guide

3.1 General Substrate Basic Requirements for All Systems

1.  Concrete substrate strength grade ≥ C25; thoroughly remove surface laitance, oil contamination, release agents, and loose/bonded layers.

2.  Substrate surface must be mechanically treated using shot blasting or diamond grinding equipment to create uniform roughness, enhancing coating mechanical interlocking adhesion.

3.  Substrate surface must have no standing water or free water; test substrate moisture content before construction and strictly match the corresponding system’s maximum moisture content requirement.

4.  Construction ambient temperature: 5–35°C; air relative humidity ≤75%; substrate surface temperature at least 3°C above dew point.

3.2 Sub-System Standardized Construction Parameters Comparison Table

Construction Procedure	Solvent-Based Epoxy Primer	Solvent-Free Epoxy Primer	Waterborne Epoxy Primer	Construction Procedure	Solvent-Based Epoxy Primer
Mixing Requirements	Pour all A and B components into mixing container; mix 3–5 min until uniform color, no stratification	Low-speed high-torque mixing (≤300 rpm) to avoid air entrapment causing pinholes; allow to stand 3–5 min for deaeration after mixing	Mix until both components are fully incorporated; may add ≤5% clean water to adjust viscosity	Mixing Requirements	Pour all A and B components into mixing container; mix 3–5 min until uniform color, no stratification
Induction/Standing Time	Allow to stand 10–20 min after mixing for full induction	No induction required; apply immediately after deaeration	No induction required; apply immediately after mixing	Induction/Standing Time	Allow to stand 10–20 min after mixing for full induction
Recommended Application Tools	Short-nap roller, low-pressure air spray	Short-nap roller, stainless steel trowel	Roller, brush	Recommended Application Tools	Short-nap roller, low-pressure air spray

3.3 Quality Control Essentials Throughout Construction Process

1.  For solvent-free epoxy primer, strictly control total batch size; calculate material pot life based on ambient temperature to avoid gelation and waste from exceeding pot life. Allow standing for deaeration after mixing to prevent film pinholes.

2.  For waterborne epoxy primer, water dilution shall not exceed 5% by proportion. Excessive water dilution reduces crosslinking density, leading to film whitening, insufficient bond strength, and diminished alkali resistance. In low-temperature, high-humidity conditions, extend curing time.

3.  When applying solvent-based primer in enclosed spaces, forced ventilation equipment must be activated, with VOC exhaust gas collection and treatment systems to meet local environmental emission control requirements. Open flames are strictly prohibited in the construction area; anti-static and fire prevention measures must be implemented.

4.  If the maximum recoat interval is exceeded, lightly sand the primer surface, thoroughly clean off dust, and eliminate the interlayer separation zone before recoating, to prevent topcoat delamination.

5.  Amine curing agents have skin irritancy. Personal protective equipment (gloves, safety goggles) must be worn during application of all three systems to avoid direct skin contact.

IV. Scenario-Based Standardized Selection Decision System

4.1 Selection Decision Logic

Step 1: Check substrate moisture content and project fire protection code requirements

Substrate moisture content >8% / Underground garages, civil defense projects, projects requiring Class A fire rating → Select Waterborne Epoxy Primer

Substrate moisture content ≤8% → Proceed to Step 2

Step 2: Check floor usage conditions and environmental control requirements

Long-term forklift heavy traffic, GMP clean workshops, food/pharmaceutical plants, projects with mandatory low-VOC environmental control → Select Solvent-Free Epoxy Primer

Light-duty warehousing, dry aged floor renovation, projects with cost as primary control factor → Select Solvent-Based Epoxy Primer

4.2 Standardized Supporting Solutions for Four Typical Application Scenarios

1.  Underground Garage / Civil Defense Project: Complete waterborne epoxy flooring system – suitable for high-moisture-content new concrete; meets Class A fire protection mandatory requirements for underground spaces.

2.  Heavy-Duty Machinery Workshop: Solvent-free epoxy primer + quartz sand intermediate coat + epoxy self-leveling finish – high bond strength, high compressive strength; long-term resistance to forklift traffic and wear.

3.  Dry Aged Industrial Floor Renovation: Solvent-based epoxy penetrating primer – lower overall cost; effectively seals porous aged cement substrates.

4.  Commercial Retail Spaces, Indoor Light-Duty Areas: Waterborne epoxy primer with thin-film epoxy finish – no pungent solvent odor; excellent indoor environmental performance.

4.3 Special Scenario Supplementary Notes

1.  Strong Acid/Alkali Corrosive Chemical Workshops: The three primers described herein serve only as sealing primers; must be paired with dedicated acid/alkali-resistant intermediate and topcoat anti-corrosion systems.

2.  Outdoor Exposed Floors: All epoxy systems have insufficient weatherability; none of the three Eapearl epoxy primers are suitable for outdoor flooring applications.

3.  Low-Temperature Cold Storage Workshops: Require low-temperature curing specialty modified epoxy primer; conventional three-system primers do not cure completely in low-temperature environments.

V. Industry Technology Development Trends and Anhui Eapearl Chemical Core Technical Advantages

5.1 Epoxy Floor Primer Industry Development Trends

1.  Continuous escalation of environmental control: National VOC emission policies tightening; market share of solvent-based epoxy flooring declining year by year; waterborne and solvent-free low-VOC systems becoming mainstream selection.

2.  Growing demand for damp substrate solutions: Construction project schedules compressed; floor construction often proceeds before concrete is fully cured; market demand for waterborne epoxy primers suitable for high-moisture-content substrates continues to grow.

3.  Industry standardization and deconceptualization: Tender projects increasingly phasing out “pseudo-epoxy” modified acrylic floor materials; technical specifications explicitly require two-component epoxy crosslinking-type primer materials.

4.  Increasing demand for full-system solutions: Market demand shifting from single primer products to complete primer-intermediate-topcoat integrated floor coating systems; primer performance directly determines overall floor service life.

5.2 Anhui Eapearl Chemical Five Core Technical Advantages

1.  Raw Material – Finished Product Integrated R&D Capability: Self-developed core raw materials including epoxy dispersions, reactive diluents, and modified amine curing agents; products precisely compatible with mainstream resin raw material systems in the market.

2.  Full-System National Standard Compliance Testing: All series of epoxy primer products have completed complete physicochemical testing per GB/T 22374-2018; VOC, tensile bond strength, and alkali resistance indicators all meet standards.

3.  Scenario-Specific Custom Formulation Systems: Dedicated formulations optimized for three key segments: damp underground spaces, heavy-duty industrial floors, and low-cost aged floor renovation, with tailored waterborne, solvent-free, and solvent-based primer formulations respectively.

4.  Full-Process On-Site Construction Technical Support: Comprehensive practical guidance including standardized construction operation manuals, substrate moisture content testing specifications, material ratio control, and pot life management, reducing on-site project quality risks.

5.  Clear Raw Material Selection Boundary Definition: Clearly distinguishes modified acrylic emulsions from genuine crosslinking-type epoxy raw materials, helping paint manufacturers and flooring contractors avoid selection errors.

VI. Quality Risk Prevention and Common Defect Traceability Solutions

All quality defects related to floor primers can be traced to three categories of causes: material selection, substrate preparation, and construction operations. The traceability and standardized prevention solutions are as follows:

6.1 Overall Floor Peeling, Complete Delamination

Defect Causes: Using epoxy-modified acrylic emulsion instead of crosslinking-type epoxy primer; substrate moisture content exceeding limit; substrate surface not mechanically ground, lacking mechanical anchoring structure; A and B components not mixed uniformly, resulting in incomplete curing.

Prevention Solutions: Replace with compliant two-component epoxy floor primer; test and control substrate moisture content before construction; uniformly shot-blast/grind substrate surface; strictly mix according to ratio for more than 3 minutes.

6.2 Film Blistering, Pinholes

Defect Causes: Solvent-based primer applied on high-moisture substrate; excessive mixing speed in solvent-free system entraining large amounts of air; waterborne primer diluted with water beyond limit.

Prevention Solutions: Replace with waterborne epoxy primer for damp substrates; low-speed mixing for solvent-free materials with standing deaeration after mixing; control waterborne primer dilution water addition within 5%.

6.3 Poor Interlayer Adhesion, Topcoat Peeling in Sheets

Defect Causes: Recoat interval exceeding standard maximum; recoating directly over hard-dried primer without sanding; insufficient primer coverage, leaving substrate pores inadequately sealed.

Prevention Solutions: Strictly follow standard recoat intervals; if time is exceeded, lightly sand, thoroughly clean dust before recoating; apply according to standard theoretical coverage rate; appropriately increase coverage for highly porous substrates.

6.4 Finished Product VOC Test Value Exceeding Limit

Defect Causes: Solvent-based primer inherently has low non-volatile matter content; adding non-matching thinners on-site; using non-standard low-quality epoxy resin raw materials.

Prevention Solutions: Select compliant Anhui Eapearl Chemical solvent-based epoxy primer; prohibit additional thinner addition on-site; for projects with strict environmental control, directly substitute with solvent-free/waterborne epoxy system.
