Gypsum Decoration Mold Making RTV 2 Liquid Silicone Rubber
1. Gypsum Decoration Mold Making RTV 2 Liquid Silicone Rubber description
XB-725# is one of the best seller.
The XB-725# is a kind of liquid RTV tin cure mold making silicone rubber with two parts, part A is the silicone rubber base, part B is the condensation curing agent. XB-725 is in the harshness of 25 shore A, then the application of XB-725# would be used to make mould of the products in medium size such as 40~50cm, such as the concrete/cement products, artificial stone, small plaster decorations, bronze statues, etc.
Its mixing ratio is 100:3, and generally 3% free catalyst would be offered. But in the same mixing ratio, the higher the temperature is, the faster the silicone rubber would be cured. So, please add the catalyst accordingly.
