description
Tin-based silicones, also called condensation-cure silicones, are two-component materials which cure at room temperature(RTV)to flexible, high tear-strength rubbers. Tin cured silicones can be poured onto models or they can be made brushable by adding a thixotropic additive. They are ideal for molds where easy release or high temperature resistance is required. Tin cured silicones can be used for casting polyurethane, epoxy and polyester resins, waxes, all gypsum products and low-temperature metals. Our tin-cured silicone systems are the most economical. They are best used for casting resins and low melt metals.


instruction
During operate the three important thing to pay attention
1. weigh theliquid silicone rubber and curing agent exatly
2. Stir theliquid silcone rubber and curing agent evenly
3.we shouldchoose the right hardness to making diffirent size of product mold
