GI-1000 is an extremely high tear, high tensile strength, two component, tin catalyzed RTV Silicone Rubber. It is designed for casting polyurethane foam, polyester and epoxy parts. GI-1000 is a good electrical insulator where high mechanical stresses are involved. It is a superior product with the following advantages over other RTV silicones:
Extremely high tear strength: GI-1000 is especially good for molds with deep undercuts and for those molds which requite flexing for part removal.
Low shrinkage: Gi-1000 offers exceptional reproduction capability. It is particularly valuable in the production of many-sided molds where the exact registrations are required.
Excellent chemical resistance: GI-1000 exhibits extremely long mold life due to unique processing techniques that were developed to meet the rigors of polyester and polyurethane casting.
Excellent shelf aging: GI-1000 retains its dimensional stability and resists embrittlement on aging.
Low viscosity: The low viscosity of GI-1000 allows for easy mixing and de-airing, ensuring smooth, even flow.
Variable cure rate: Several activators are available for special or unusual applications.
Working Time: 1.5 to 2.5 Hours
Cure Time: 16 to 18 Hours
Shelf Life: 6 Months
Hardness, Shore A: 32 +/- 4
