Ultrafine Silica Powder

Silicon powder is a neutral inorganic filler, does not contain crystal water, does not participate in the curing reaction, and does not affect the reaction mechanism. It is a stable filler with a neutral surface. Good flexibility.
It has good wettability to various resins, excellent adsorption properties, easy blending, and does not produce agglomeration.
It can reduce the exothermic peak temperature of epoxy resin curing reaction, reduce the thermal expansion coefficient and curing shrinkage rate of the cured product, thereby eliminating internal stress and preventing cracking.
Stable chemical properties, good UV resistance, strong chalking resistance, good wiping resistance
Due to the fine particle size of silica micropowder, it can effectively reduce and eliminate the phenomenon of precipitation and stratification.
The silica micropowder is pure and inert, so that the cured product has excellent insulating properties and arc resistance.
Low oil absorption, the addition of silicon micropowder can reduce product cost and reduce the amount of solvent.
