Product Cure Type Selector
Addition Curing
-
For engineering design, prototyping, and architectural fabrication
-
Use platinum catalyst
-
Cure can be heat accelerated
-
Exhibit virtually no shrinkage when cured at room temperature
-
Offer better chemical resistance
Addition-cure moldmaking products are characterized by extremely low shrinkage during curing as well as high temperature stability. These materials are therefore appropriate if a high dimensional accuracy is required of the replica. Addition-cure silicone elastomers are susceptible to cure inhibition when in contact with certain materials and chemicals such as amines, sulfur and organic tin salt containing products and substrates.

Condensation Curing
-
For molding figurines, decorative reproduction, and making transfer pads
-
Provide outstanding resistance to inhibition
-
Use tin catalyst
-
Offer variable cure times at room temperature
Condensation-cure moldmaking products are characterized by high tear strength and elasticity. Together with a very good flowability, this allows detailed reproduction of complex originals with deep undercuts, without harming the original. Often one- or two-part molds are sufficient. The multitude of possible combinations with curing agents and additives allows customizing products for different purposes.
