Titanate Coupling Agent LD-144

Description

Product Introduction

Titanate Coupling Agent LD-144 is a functional titanate coupling agent designed for polymer, resin, rubber, pigment, and filler systems. It can improve the interaction between organic materials and inorganic fillers while supporting better filler dispersion and processing performance.

LD-144 is suitable for polypropylene, PVC, nylon, thermoplastic polyester, melamine resin, and epoxy resin systems. It can be used as a surface-active treatment agent for pigments and fillers, helping improve dispersion and processing characteristics in high-filling formulations.

The product is particularly suitable for calcium carbonate, clay, kaolin, metal oxides, wollastonite, aluminum hydroxide, talc, silicon dioxide, titanium dioxide, carbon black, ferrite, and phthalocyanine pigments.

Manufactured by Yangzhou Lida Resin Co., Ltd., LD-144 is designed for industrial applications where filler loading, pigment dispersion, flowability, flexibility, and material compatibility are important.

Key Features & Advantages

1. Improved Filler Loading

LD-144 can help increase the amount of filler incorporated into resin or rubber systems. This makes it suitable for formulations requiring higher filler content while maintaining practical processing performance.

2. Enhanced Pigment Dispersion

The coupling agent improves the dispersion of phthalocyanine pigments in organic systems. It can also help reduce viscosity in systems containing inorganic materials, supporting smoother processing.

3. Organic-Inorganic Coupling

LD-144 provides coupling action between organic polymers or resins and inorganic fillers. This helps improve compatibility within filled formulations and supports more uniform material properties.

4. Good Flowability

Compared with the TTS series, LD-144 provides better water resistance according to the supplied product information. It also offers good flowability and can facilitate pigment grinding and filler treatment.

5. Suitable for High-Filling Systems

The product is suitable for formulations with relatively high filler content. It can be used in light-colored and white products while helping maintain a brighter appearance.

6. Support for Rubber Filler Treatment

LD-144 can be used to treat mixed fillers for rubber applications. Treated argil and kaolin can also replace part of the carbon black in certain rubber filling systems, subject to formulation testing.

7. Improved Mechanical Performance

When properly formulated, LD-144 can help improve impact strength and flexibility while allowing increased filler addition. The final effect depends on the resin, filler, processing conditions, and dosage.

8. Processing Cost Optimization

By supporting higher filler loading and better filler dispersion, LD-144 can provide formulation flexibility for manufacturers seeking to optimize material consumption and overall production costs.

The appropriate dosage and treatment method may vary according to the selected resin, filler type, filler loading, and processing conditions.

Suitable Fillers & Pigments

Titanate Coupling Agent LD-144 is suitable for treating and processing various inorganic fillers and pigments, including:

• Light calcium carbonate

• Heavy calcium carbonate

• Clay

• Argil

• Kaolin

• Metal oxides

• Wollastonite

• Aluminum hydroxide

• Titanium dioxide

• Carbon black

• Ferrite

• Phthalocyanine pigments

For fillers containing a certain amount of free water, processing conditions should be evaluated according to the specific material and formulation.

Application Areas

Polymer and Plastic Compounding

LD-144 can be incorporated into filled polymer systems to improve filler dispersion and organic-inorganic compatibility. It is suitable for applications based on PP, PVC, nylon, thermoplastic polyester, and other compatible materials.

Rubber Compounding

The coupling agent can be used for mixed filler treatment in rubber formulations. Treated clay and kaolin may be used to replace part of the carbon black in suitable formulations after application testing.

Pigment Treatment

LD-144 can improve the dispersion of phthalocyanine pigments in organic systems and support smoother processing of pigment-containing formulations.

High-Filler Formulations

For manufacturers using large amounts of inorganic filler, LD-144 can help improve filler incorporation and processing behavior while supporting formulation flexibility.

Light-Colored and White Products

The product can be used in light-colored and white formulations where filler loading and pigment dispersion need to be balanced with final appearance.

Recommended Usage Method

For general filler or pigment treatment, dilute LD-144 with liquid paraffin at a 1:1 ratio.

The diluted mixture can then be sprayed onto the pigment or filler while operating a high-speed kneader. Mix for approximately 15 minutes, then add the resin and other additives according to the original production process.

Recommended Dosage

The recommended consumption is:

• 0.5–2.0% of the total pigment/filler amount

• Recommended starting dosage: 1.0%

The optimum dosage should be established through testing because the required amount can vary according to filler type, resin system, filler loading, processing conditions, and final product requirements.

Product Handling & Storage Notes

• Keep the product away from water.

• Store and handle it according to appropriate industrial chemical handling practices.

• Color differences may occur and do not affect product quality according to the supplied specifications.

• Validity period: 2 years.

• Application testing is recommended before full-scale production.
