Two component transparent silica gel should pay attention to the problem

2020-03-02

Transparent silica gel raw material can also be called add molding mold silica gel, only add molding silica gel can achieve full transparency, condensation type can only be translucent silica gel. Transparent silica gel raw materials, mainly 1:1, and 10:1, is a two-component, one component is platinum curing agent.


Two-component transparent silica gel should be noted during operation:

液態(tài)硅膠

   

This silica gel should not contact with any other condensation type silica gel, do not contact with any organic compounds such As N, P, S, Sn, Pb, Rg, Bi, As plasma compound, otherwise it will cause the curing agent poisoning, causing the curing agent poisoning, causing the phenomenon of silica gel will not cure


Temperature range of -65°C to 200°C can be used for a long time and maintain soft elastic properties, electrical and chemical stability, water resistance, ozone resistance, climate aging resistance, non-corrosive, physiological inertia, non-toxic and tasteless, low line shrinkage.


Components A and B are mixed evenly at 1:0.95-1.05 and can be irrigated after vacuum defoaming. The operation time depends on the temperature (0.5-3)H, the curing time (room temperature) 12-24h, and the curing time can be in tens of minutes at the temperature of 80-120°C. The operation time of room temperature quick-drying type is less than 20 minutes, and the curing time is 1 hour.
