Attention
1. The rubber material should be sealed and stored, and the mixed rubber material should be used up within the specified time to avoid waste
2. Do not let the rubber material and contain nitrogen (N), sulfur (S), phosphorus (P), tin (Sn), lead (Pb), mercury (Hg). Contact with alcohols, water, etc., such as organotin compounds and silicone rubber containing organic tin. Sulfur, sulfide, sulfur-containing rubber, amine compounds, and ammonia-containing materials. Also, do not contact containers or molds that contain condensation rubber. , Otherwise, the addition molding liquid silicone will be sticky, incompletely cured or even not cured
