Transparent Silicone Rubber Liquid Silicone Rubber Mould Making Liquid Silicone Rubber

Product DescriptionPourable, addition-curing, two-component silicone rubber that vulcanizes at room temperature. Non-toxic, odorless, two-component liquid silicone rubber, are two-componentmaterials.Resistance high temperature of 250℃,shrinkage rate lower than 0.1%.
Addition silicone rubbers can be applied to PU resin casting, general mold making, GRC and concrete molding, superior manual mold design, food grade molding application, rapid prototyping(urethane casting/ silicone tooling/ vacuum casting).
• Almost nil shrinkage, cure at room temperature
• High Shore A hardness (approx.40)
• Good transparency, high tear strength
• Food grade silicone(environmental, odorless and nontoxic)
• High resistance to high temperature and aging(resist -60 to 150℃)
• High chemical resistance to aggressive components of some types of resins
• Outstanding resistance to common casting resins
The platinum catalyst is in component B.A and B components may only be used together if they have the same batch number. Addition silicone rubber can react with compounds such as phosphorus, ammonia, acid, mercaptan, it will produce harmful substances.

The 'Best use before end' date of each batch is shown on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
