for artificial stone liquid molded rtv silicone
RTV mold making addition silicone are generally named as two-part addition silicone rubber that vulcanises at room temperature.Part A is a flowable liquid, part B is the curing agent(platinum catalyst). It features an exceptional fluidity ,good operability,excellent physical properties and very low shrinkage.
The mixing ratio between Part A and Part B can be 10:1 or 1:1.
RTV silicone rubber for mold making application :
· Rapid prototyping (urethane casting/silicone tooling/vacuum casting)
· GRC and Concrete moulding
· PU resin casting
· General Mouldmaking
· Superior manual mold design
RTV silicone rubber for mold making main properties :

RTV silicone rubber for mold making Storage
Sealing storage in the environment of dry, cool and ventilated. storage temperature should be kept during 0~40°C.
RTV silicone rubber for mold making Shelf-life
12 months under above conditions. It can be used after shelf life if the technical data is qualified.
RTV silicone rubber for mold making FAQ
1. Why should the RTV-2 molding silicone rubbe mold be reused only for a few times?
It can be due to the following reasons:
a. Adding too much silicone oil in to silicon rubber.
b. Using the silicon rubber with a high hardness to make molds for small sized products with delicate and intricate designs .
RTV silicone rubber for mold making Warm tips :
1. weigh theliquid silicone rubber and curing agent exatly .
2. Stir theliquid silcone rubber and curing agent evenly .
3.we should choose the right hardness to making diffirent size of product mold
