Tin Cured RTV2 Silicon Silicona Silicone with 3% Free Catalyst for Making Mold
Condensation Molding Silicone is generally named as two-parts silicone rubber that is vulcanized
at room temperature, and used for model designing work of all kinds of products with simple
or intricate patterns, such as artificial stones, craft stones, gypsum crafts, GRC/GFRC, GRG,
fireplaces, fountains, ornaments, resin crafts, resin marble works, shoe soles, Art sculptures,
decorations, candles, soaps, PU, furniture moldings, etc. With good resistance to deformation, heat,
acid, alkali and expansion, finished silicone molds have very good performance in reproduction
process and fine details on designing models

Condensation molding silicone rubber is a kind of flowing liquid, and it consists of two
components,
part A is a flow-able liquid silicone rubber, part B is the curing agent.
1. Firstly, after your previous work of dealing with the original model, take some liquid silicone
rubber, add 3% curing agent of the amount of silicon and mix them evenly.
2. Then after vacuum pumping the mixture, you can pour it into the mold frame.
3. The silicone mold will be cured in 3 to 5 hours.
