Transparent powder (powder, paint special)
English Name: powder Transparent
Molecular formula: Na2S04
Molecular weight: 142.04 (according to the 1979 international atomic scale)
A S C number: 7757-82-6
Transparent powder (powder, paint special) characteristics
High transparency, good whiteness, refraction 1.54, density 2.3, range 25, non-toxic tasteless, with high transparency. Refractive index of the filling material itself and the refractive index of most of the synthetic resin was very close to, so fill in the amount of filler does not affect the transparency of the finished product; can improve the scratch resistance of the product surface smooth and wear; low oil filling capacity, reduce the manufacturing cost of the product.
Performance of transparent powder (powder and coating)
White crystalline powder. , refraction 1.54, density 2.3, non-toxic. Transparent filler. Transparency: the refractive index of the filling material itself and the refractive index of most of the synthetic resin was very close to, so the packing of the filling quantity does not affect the transparency of the finished product;
High hardness: can improve the surface smoothness and abrasion resistance of the product;
Low oil: to reduce the manufacturing cost of the product;
Easy to disperse: the resin has good wettability, good adsorption performance, easy to disperse;
Stability: with excellent weather resistance and excellent corrosion resistance.
Transparent powder (powder, paint special purpose)
Application of transparent powder in coatings
One, in the adhesive, ink in the amount of added, can improve its comprehensive performance, and reduce costs
Two, PU, PE and NC applied in wood paint, transparent water and oily wood coatings increase transparency, hardness, improve collapse pit, improve the gloss and oxidation resistance, increase the fluidity of liquid paint
Application suggestions
One, in the high-grade transparent primer in the amount of transparent powder should not be too much, 3%--8% is appropriate;
Two, the production of feeding, in the mixer operation process transparent powder should be slow small amount of investment, otherwise it may affect its dispersion;
Three, anhydrous transparent powder added in the primer, due to increase the hardness and toughness of the film, grinding may have a slight impact;
Four, high water content, to keep good, do not be affected with damp;
Five, easy to absorb moisture, it should not be stored for a long time, manufacturers should be used within 2 months.
