Description
RTV silicone elastomer of the bi-component poly-additive type (base and catalyst) which cures at room temperature. Suitable for duplicating models with fine cavities. The main property of the product is its remarkable fluidity.
The main properties of the vulcanized product are:
- High chemical resistance to aggressive components of certain types of resin;
- Extremely high tensile and tear resistance;
- High accuracy to reproduce very fine details;
- Dimensional stability in high time and mold indeformability;
- Remarkable resistance to temperatures and aging;
- Exceptional anti-adhesive properties.
Application
- Manufacture of molds and models (for its remarkable reproduction accuracy, high dimensional stability and high mechanical strength).
- Main application: indicated for the realization of objects in polyester resins.
