RTV-2 Silicone Mold Kit for General Purpose Mold making
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-2 Silicone Mold Kit for General Purpose 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-2 Silicone Mold Kit for General Purpose Mold making Warm tips :
