RTV Mold Making Silicone (Addition-cure type)

Description of RTV Mold Making Silicone for rapid prototyping (Addition-cure type) :

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.

Main application of RTV Mold Making Silicone for rapid prototyping (Addition-cure type) :

Rapid prototyping (urethane casting/silicone tooling/vacuum casting)
GRC and Concrete moulding
PU resin casting
General Mouldmaking
Superior manual mold design

Main properties of RTV Mold Making Silicone for rapid prototyping (Addition-cure type) :

almost nil shrinkage
high chemical resistance to aggressive components of some types of resins
good tear strength (this feature ensures higher resistance to wearing and shearing)
high degree of precision in reproduction
high dimensional stability over time and non-deformability
high resistance to high temperatures and ageing (resit to -60-200°C)
excellent non-stick effect
environmental, odorless and nontoxic

Notice:

All above addition silicone is forbidden to mix with organic compounds of condensation cure silicone rubber,otherwise, the silicone rubber will not cure, and also should not mix with organic compounds containing S, P, N as well as metallic salt of organic acids. It also will cause this product cure uncompletely or not cure.
