Product detailed description
Green Stuff World Silicone Putty has a pot life of 2.5 minutes with a cure time of 10 minutes. Shrinkage is very low (0.03%) and when cured is exceptionally strong and durable (tear strength 6 N/mm). It will resist temperatures up to 150ºC.
Other applications include making fast mold impressions from almost any surface, orthotics, jewelry making and more.
The cure of the silicone putty may be inhibited by certain contaminants in or on the pattern to be molded resulting in tackiness at the pattern or a total lack of cure throughout the mold. Wear vinyl gloves only, since Latex gloves will inhibit the cure of the rubber. Also, tin-cure silicone, sulfur clays, certain wood surfaces, newly cast polyester resin, epoxy or urethane rubber may cause inhibition.
If compatibility between the silicone rubber and the surface is a concern, a small-scale test is recommended. Apply a small amount onto a non-critical area of the pattern. Inhibition has occurred if the rubber is gummy or uncured after the cure time has passed.
