Product Name: Platinum Cure Silicone Rubber for Rapid Prototype

Product Model: XB-640#, XB-645#, XB-650#

Product Description:

The XB-640#/645#/650# is a kind of liquid RTV addition cure mold making silicone rubber with two parts, part A is the silicone rubber base, part B is the platinum curing agent. The application would be used to make mould of the products in large size.

But the most general application of this kind of clear silicone rubber with large hardness is for prototype design of a variety of precision parts mold making, such as aerospace parts, auto parts, military supplies, silicone robot molds, cars, ships and other accessories. They are also used for the jewel mould making.

Its mixing ratio is 1:1 and its curing would be heavily impacted by the temperature.
