Product Description
Description
GRC mold silicone rubber is liquid bi-component silicone rubber,which includes part A and pare B, part A is flow-able liquid silicone rubber, part B is vulcanizing agent, the silicone can form quickly after mixing. Whether condensation cure silicone rubber or addition cure silicone rubber, both of which are suitable to product and duplicate GRC products, the former is industrial silicone rubber with the ratio of 100:5, the latter is food grade silicone rubber with the ratio of 1:1 or 10:1.
Application
GRC mold silicone rubber is suitable for architecture,decoration mold making,such as GRC European-style decorative components,plaster line,plaster waistline,architecture decoration,backdrop,art stone,roman column,human statue,garden cement sculpture,statue,rocks,weathered stone,slate mold making.
Features
1.Clear pattern,delicate textures,good simulation effect especially for artificial stone mold making.
2.Lower shrinkage to avoid a waste of silicone mold.
3.High tension and tear strength,non-deformation.
4.High duplication times,more durable,acid and alkali resistance.
5.Easy-operation,time-saving and labor-saving.

Attention
1.The amount of catalyst should depend on temperature,Higher temperature,less addition.
When the curing agent is used too much, the mould will be hard and brittle. When the curing agent is used too little, the operation time will be prolonged.
2.In order to use silicone mold the most effectively,please use it after checking at least 24 hours.
