Qingdao scratch and abrasion resistance Glass Powder glass powder Waterborne paint Role in
1、 Product Introduction
The hardness of water-based paint is generally low due to the soft hardness of the raw material resin or emulsion used, and it is generally necessary to add auxiliary Or high hardness powder to increase hardness. Water property developed by Youhe Industrial paint Hardened and wear-resistant glass powder is made of high hardness and high permeability silicate glass microcrystalline raw materials by high purity and ultra-fine grinding and grading.
Main features: Spherical modification of high-purity microcrystalline structure Micropowder , high hardness, high permeability, small particle size and extremely narrow distribution
Main applications: For various water-based industrial paints (such as water-based metal baking paint, glass baking paint, plastic paint, etc.)
Main advantages: Improve hardness and wear resistance, not affect gloss and pigment color, good anti sedimentation, good recoating, strong weather resistance
Main competition: The comprehensive cost performance ratio is superior to the general water-based glass powder in the market
2、 Product performance characteristics
1. The glass powder has strong temperature resistance, light aging resistance, chemical stability, storage and use stability, good filling, and can improve the chemical resistance, weather resistance, water resistance, yellowing resistance, etc. of the paint film;
2. This glass powder is a standard rhombic microcrystal with small particle size and narrow and uniform distribution. It is hydrophilic and has compatibility, dispersibility and anti sedimentation in water-based paint; No large particles, no particles in film spraying, good leveling, little impact on gloss, good hand feel.
3. This glass powder has a high content, and its refractive index is very close to various water-based industrial paint resins (such as WPA/WPU/WPUA, etc.). It has good transparency when used in varnish, and can not cover the color of pigment when used in paint, and can improve the color plumpness.
4. The glass powder has high hardness (Mohs hardness 7.0~7.8) and dimensional stability, which can significantly improve the hardness, wear resistance and scratch resistance, fullness and impact resistance of the paint film.

4、 Application advantages and method suggestions
1. This glass powder can be used in various water-based industrial paints (such as water-based metal baking paint, glass baking paint, plastic paint, etc.) to obtain high hardness without affecting transparency and recoating, and can significantly improve the abrasion resistance and scratch resistance of the paint film. The recommended addition amount is generally 5~12%.
5、 Application precautions and risk tips
1. Due to the high specific gravity of this glass powder, excessive addition may increase the difficulty of coating anti settling. It is recommended that the customer conduct strict testing and properly improve the anti settling system before official use.
2. Due to its high hardness, if the glass powder is dispersed at high speed or repeatedly ground for a long time during use, the coating will blacken due to increased wear on the machine.
