Microcrystalline
powder
color: Hoariness, White
mesh: 40-60,120,150,200,325
Properties
and Application:
Microcrystalline powder is a new-type inorganic multifunctional
powdered filling material developed by our company. The microcrystalline
powder is of high content, good whiteness, high activity,
and easy to be dyed and modified. It is anti-acid and alkali-resistant,
anti-corrosion, heatproof of strong insulation, small thermal
expansion coefficient, strong weather resistance, good suspensibility
and smoothness. It is of functions such as anti-solidifying
and anti-cracking, ultraviolet-proof, anti-aging, reinforcement,
etc., so it is the ideal new-type filler.
