Titanate Coupling Agent LD-401

Product Introduction

The Titanate Coupling Agent LD-401 is a phosphate polymer designed for use as a coupling agent, flame retardant and antioxidant in various coating, resin and composite systems. It has good adhesion to inorganic materials such as metal and glass and can support improved filler dispersion and coating performance.

LD-401 features a low-viscosity transparent liquid appearance, a decomposition temperature of 260°C, a flash point of 130°C, and a density of 0.945 g/cm³. It can be used in both solvent-based and waterborne coating systems, making it suitable for different formulation and processing requirements.

In coating applications, LD-401 can provide catalytic curing effects and help lower baking temperature. It can also improve the dispersion of pigments and fillers, enhance adhesion to inorganic substrates, and support improvements in mechanical, abrasion-resistant and anti-aging properties depending on the formulation.

Yangzhou Lida Resin Co., Ltd. supplies LD-401 for industrial applications involving coatings, resins, pigments, fillers, inks and glass fiber reinforced plastics.

Key Product Features

1. Phosphate Polymer Structure

LD-401 is a phosphate polymer with functional properties that support its use in coating and resin formulations. It can be incorporated into systems requiring coupling, adhesion, dispersion, flame retardancy or oxidation resistance.

2. Oxidation Resistance and Flame Retardancy

The product provides oxidation-resistant and flame-retardant properties, making it suitable for formulations where these characteristics are required.

3. Improved Adhesion to Inorganic Materials

LD-401 has good adhesion to inorganic substrates including metal and glass. It can also improve the adhesion of selected resin systems to different metal surfaces.

4. Pigment and Filler Dispersion

When used to treat inorganic fillers or incorporated during the grinding stage, LD-401 can improve the dispersion of many pigments and fillers. It can also help improve filler anti-settling performance in suitable formulations.

5. Support for Lower Baking Temperature

For coating applications, LD-401 can provide a catalytic curing effect and help lower the required baking temperature, depending on the coating formulation and processing conditions.

6. Low-Viscosity Liquid

The product is supplied as a low-viscosity transparent liquid, facilitating incorporation into suitable coating, ink and resin formulations.

7. Compatible with Solvent-Based and Waterborne Coatings

LD-401 is suitable for solvent-based and waterborne coatings. For waterborne systems, it can be processed through high-speed grinding followed by emulsion dispersion, or dispersed with the assistance of a surfactant or hydrophilic co-solvent.

Physical and Chemical Information

Applications

Unsaturated Polyester FRP

LD-401 can be used in unsaturated polyester fiber-reinforced plastics. It can help improve the mechanical properties and anti-aging performance of glass fiber reinforced plastic systems.

High-Solid Titanium Dioxide and Clay Coatings

In high-solid-content coatings containing titanium dioxide, clay and epoxy resin, LD-401 can help reduce titanium dioxide and solvent requirements while allowing increased clay filler loading.

It can improve the adhesive force of the coating to glass and metal while maintaining system viscosity under suitable formulation conditions.

Saturated and Unsaturated Polyester Coatings

LD-401 can improve the loading of many pigments and fillers in saturated and unsaturated polyester systems. It can also contribute to improved coating gloss.

Acrylic Resin Coatings

The product can improve the abrasion resistance of acrylic resin coatings when used at an appropriate dosage.

Polyvinyl Acetate Latex Paint

LD-401 can improve pigment and filler dispersion in polyvinyl acetate latex paint. It can also support improved abrasion resistance of fillers and coatings.

Chlorinated Rubber Coatings

For chlorinated rubber systems containing high levels of barite powder, LD-401 can improve the dispersion of the filler and contribute to better formulation uniformity.

Metal and Inorganic Material Adhesion

LD-401 can improve the adhesion of melamine resin to steel, iron, aluminum, tin, brass and other inorganic materials.

It can also improve the adhesion of polyester, polyurethane and epoxy resins to mild steel.

Inorganic Filler Treatment

LD-401 can be used for treating inorganic fillers such as metal powders. The treatment can improve filler dispersion and anti-settling properties, depending on the formulation and processing conditions.

Performance Benefits by Application

Recommended Usage and Dosage

LD-401 is recommended to be added during the grinding stage.

The suggested dosage is:

0.5–0.8% of the total pigment/ink amount

The optimum dosage may vary according to the specific formulation system, pigment type, color variety, filler content and processing conditions. Formulation testing is recommended to determine the appropriate addition level for each application.

Application in Waterborne Coatings

LD-401 can be used in waterborne coating formulations through suitable dispersion methods.

Possible processing approaches include:

• High-speed grinding followed by emulsion dispersion in water

• Dispersion with the assistance of a suitable surfactant

• Dispersion using a hydrophilic co-solvent

The selected dispersion method should be determined according to the coating system and formulation requirements.

Application in Solvent-Based Coatings

LD-401 is also suitable for solvent-based coatings. Its low-viscosity liquid form facilitates incorporation during the formulation or grinding process.

It can be used in systems containing pigments, fillers, epoxy resin, polyester resin, acrylic resin and other compatible coating components.

Processing Considerations

The recommended addition point is the grinding stage, where LD-401 can interact with pigments and fillers to support dispersion.

Because optimum dosage depends on the formulation, users should evaluate the product based on pigment type, filler loading, resin system, coating solids content and desired performance. Excessive or insufficient dosage may affect the final coating properties.

For waterborne formulations, suitable dispersion equipment and processing conditions should be selected to achieve stable incorporation into the aqueous system.

Storage and Handling

LD-401 should be handled according to standard industrial chemical handling procedures. Users should consult the applicable technical documentation and safety information before storage, transportation and formulation.

Before full-scale production, compatibility and dosage testing are recommended for the specific resin, pigment, filler and coating system.
