DESCRIPATION

MC Silicone RTV2 mold making rubber is a two-component material, consisting of Part A base silicone and Part B CA30 curing agent, cures at room temperature by a condensation reaction. These materials can be cast into the cured silicone mold: plaster, polyurethane, PU, GRC, cement, resin, polyester, wax etc..

STORAGE

When stored at or below 30 C(85F) in the original unopened containers, RTV2 Silicone Base and CA30 Curing agent have a usable life of 10 months from the date of production. After 10 months stockpiles use the Stir to mixing the Part A silicone for some mins, then the silicone can be use again, no influence for other performance.

 

Packing

20kg/drum,25kg/drum or 200kg/drum of Part A base silicone

0.25kg/bottle,1kg/bottle and 10kg/bottle of Part B CA30 Curing Agent
