Application and evaluation of Tianshi aluminum powder directional wax in water-based industrial paint

In the field of water-based metallic paint, the directional arrangement of pigments directly affects the metallic texture and random color effect of the coating. Tianshi Twax-7062 is a directional arrangement additive specially developed for water-based industrial paint. Through unique rheological control technology, it effectively solves the problem of directional arrangement of aluminum powder in metallic paint, while improving the flash effect and ensuring the coating’s durability and glossiness.

Conventional wax additives generally have three major technical bottlenecks

Traditional EVA wax emulsion: poor stability, large fluctuations in directional effect

Polyamide wax slurry: difficult to disperse, complex operating process

Universal thickener: affects coating gloss and chemical resistance

Technical innovation of Tianshi Twax-7062

Through molecular structure innovation and process optimization, three major breakthroughs have been achieved:

√ Directional enhancement: improve the regularity of aluminum powder arrangement

√ Long-term stability: storage period extended to 12 months

√ Compatible Upgrade: 0 conflict with existing formulation system

Based on the special structure of ethylene vinyl acetate (EVA) copolymer, Twax-7062 achieves precise orientation through dual functions:

1. Physical anchoring: Nano wax particles form a three-dimensional network structure to effectively support aluminum powder particles;

2. Rheological regulation: The thixotropic system realizes the intelligent switching of “flow during construction-setting during static”;

Ensure that the aluminum powder is arranged in an orderly manner during the film formation process, eliminate defects such as cloud spots and color differences, and improve the metal flash index.

Performance of Twax-7062:

Easy to operate: can be added directly without pre-dispersion, compatible with various resin systems;

Wide adaptability: low sensitivity to solvents, excellent anti-settling and construction properties during storage and construction;

Environmental protection: zero VOC emissions, meeting REACH standards.

Application advantages of Twax-7062:

PH stability, formula adaptability, and strong versatility;

Good resistance, will not have a negative impact on the chemical properties of the paint film such as water resistance and salt water resistance;

The prepared aluminum powder paint has good gloss stability and dynamic flash index;

The prepared coating has excellent shear thinning ability.

Conclusion:

Tianshi Twax-7062 focuses on strong low shear and structural viscosity recovery, high thixotropy value, and good directional arrangement effect.

Anti-settling and anti-sagging of pigments in color paint systems; anti-water separation, anti-settling and thixotropy of single-component acrylic systems; PUD or 2KPU systems also have good aluminum powder orientation, anti-settling, and thixotropy; suitable for water-based fluorocarbon systems, low-VOC water-based resin systems, etc.
