Description of Tin Cure Silicone Rubber
HN-6XX series silicone is a tin-curing silicone,consisting of two components, A and B, in aratio of 100:2. It is a silicone that is cured bycondensation reaction at room temperatureafter being stirred evenly.
Application of Tin Cure Silicone Rubber
HN-620 A/B industrial two-component liquid silicone rubber is engineered for architectural mold manufacturing. It is ideal for casting and replicating large cement components, gypsum pieces, cultural stone, artificial stone, Roman columns and stone carvings for construction & decorative projects.
Additionally, this silicone suits craft mold production for simulated plant & animal sculptures, resin crafts, plaster artworks, poly resin ornaments and carved Buddha statues.
Feature of Tin Cure Silicone Rubber
1. Outstanding tear strength, excellent resistance to extreme temperatures, acid, alkali and aging.
2. Superior fluidity enables fast self-defoaming and effortless demolding, with no whitening on cast finished pieces.
3. Molds withstand repeated casting cycles and deliver extended service lifespan.
4. Linear shrinkage rate below 0.2%.
5. Customizable color, hardness, viscosity and working time to match your production requirements.
