Tin Cured Silicone for Molding
INTRODUCTION
Tin cured silicone is specially developed for mass production of cement and stone products with high strength.This silicone is specially developed according to the characteristics of heavy cement products easy to damage the mold fine pattern and fine grain which solves the problem that other hard mold materials can not copy the pattern design on the cement surface.
APPLICATION
It is especially suitable for the production of silicone molds for large stone, gypsum, cement components, cultural stone, background wall, sandstone stone carving and other products. According to the advantages of cement molding silicone, the patterns of the above products can be copied perfectly, with high molding times, aging resistance and tear resistance. So as to save the production cost.
