Maximold
MAXIMOLD is a high performance, two component, tin catalysed RTV silicone rubber. It is designed as a 37 Shore A, giving a firmer, medium viscosity rubber providing excellent physical properties. Maximould displays good dimensional stability, low linear shrinkage and features a coloured catalyst to ensure thorough mixing. It is ideal for larger molds where a higher degree of self-support is required. Also recommended for two part or other matrix molds. Ideal for -
- Multi-Purpose Moldmaking
- Two part or matrix molds
- Polyester, Polyurethane & Plaster Casting
- Large Rock & Garden Art Molds
Size: 550gm, 1.1kg, 5.5kg
