Product Description

Bo Tech Silica Powder can be as a filler to all the coating pigment industry customer
Appearance: white yellowish powder
2, Application: PU, PE, NC end, finish 3, Features: 1, high transparency, its refractive index led a majority of the refractive index of synthetic resin is very fullness, scratch resistance increase (usually more than can be mentioned 1-2h), a primer that is able and has a top coat effect.
3, is extremely filling.
4, with anti-yellowing, high temperature, the effect of weathering (part of the product microstructure ).
5, buy low, sell oil, how much amount will not increase the ratio of the viscosity of paint.
6, because of its chemical inert, and make the range more widely.
7, easy to disperse, the use of high-speed dispersion 5-10 minutes.
8. Used in the paint, the paint can increase the hardness, toughness, ability to improve the scratch resistance of paint film, partially replace the expensive glass powder.
2) 9. Used in the paint in the role with extinction, may partial substitution of extinction powder, used in paint, you can improve product durability;
4, chemical composition and physico-chemical indicators:
1) the chemical composition SiO2 ≥ 75% MgO ≥ 12% AI2O3 ≥ 10% surface water ≤ 1% (more than indicators dry basis) Volatile (including crystal water) ≤ 18.8%
2) physical and chemical indicators of the average particle size: 3 ± 0.2um PH value of 8-8.5 weight: 2.7g/ml oil absorption: 30 ± 2 Whiteness: ≥ 93% of the 5 s estions: 1) matt finish, the recommended dosage of paint volume of 2% -5% better; 2) in the colored finish, add a level up to about 10% of the amount of paint
