Liquid molding silicone rubber/ (RTV) silicone rubber 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.

Rtv Liquid Moulding Silicone Rubber( for Concrete, PU Resin , Gypsum Casting)

1. Application of rtv liquid moulding silicone rubber :
liquid molding casting silicone rubber is mainly applied for making various molds,such as reproduction of poly resin, epoxy, polyurethane-polymer, plaster, gypsum casting and moulding, soaps, candle & lighting, architecture, decorative  arts and crafts, plastic toy, gift and stationery, big statue, cultural relic product, etc..

2.Features of rtv liquid moulding silicone rubber  

RTV liquid moulding silicone rubber has the following features

a. low viscosity, exceptional fluidity and easy operation : 21000 cps suitable for pouring
b. resistance to deformation, high-temperature 220 degree centigrade
c. acid, alkali and ageing-resistance
d. low shrinkage< 0.2%
e. good tensile strength  36±2 (kgf/cm)
f. high reproduction times

3. Operation tips of rtv liquid moulding silicone rubber

 a. adding too much silicone oil will destroy the molecular of silicone rubber, which will cause a decrease of the tensile and tear strength of the mold and deformation may occur.

b. remember to take the proper silicone rubber to make the mold for suitable products. for products with delicate and complicated patterns, you are expected to use soft silicone to make molds. While for products with easy and smooth patterns, you should choose hard silicone rubber.

Liquid molding silicone rubber/ (RTV) silicone rubber 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
