*The above info. is based on room/material temp at 75F.

RTV 3040 is a clear, high strength, addition cure silicone rubber compound.

It isformulated to be used with multiple catalysts to cure overnight at room temperature or within hours at elevated temperature to give a variety of hardness. Its low viscosity makes the product easy to pour and quick to degas.

MIXED PROCESSING PROPERTIES WILL BE AFFECTED  BY TEMPERATURE VARIATIONS
A decrease in work life and pot life may be expected to occur at temperatures exceeding75°F(24°C). Room temperature curing moldmaking rubbers are particularly sensitive to higher temperatures. Refrigeration of the base (Part A) prior to use in hot environments has shown to improve the handling properties of these materials.

Lower temperatures will increase the work life and pot life of this material.

Cure temperatures below 68°F (20°C) are not recommended and have been found to cause a reduction in final cure hardness and physical properties.This system contains a platinum CATALYST, which may be inhibited by materials found in some organic polymer systems, chlorinated solvents, and some substrates.

Especially troublesome materials are: amine cured epoxies, sulfur cured organic rubber systems such as natural rubber, polysulfide rubber, latex rubber and adhesives, sulfur containing modeling clays, PVC coated surfaces, and tin catalyzed silicone RTV rubbers. A patch test to determine compatibility is recommended when doubts exists.
