Product Description

 Clear Liquid Silicone Rubber

 RXsilicone  1340

Addition Cure Mold Making RTV2 Silicone Rubber

Pourable, addition-curing, two-component silicone rubber that vulcanizes at room temperature. Non-toxic, odorless, two-component liquid silicone rubber, are two-component materials.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


Important note

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.

Packing information

1. Ratio 1:1, the packing of Base A and Catalyst B

   40kg/Set(Base A 20kg+ B catalyst 20kg)

   400kg/Set(Base A 200kg+ B catalyst 200kg)   

2. Ratio 10:1, the packing of Base A and Catalyst B

   22kg/Set(Base A 20kg+ B catalyst 2kg)

   220kg/Set(Base A 200kg+ B catalyst 20kg)



Components A and B of the addition-curing grade contain only constituents that over many years have proved to be neither toxic nor aggressive. Special handling precautions are therefore not required.
