Condensation Cured - Silicones

Ultrasil®

Ultrasil is a general purpose, fast set Silicone. It is a two component, tin catalysed RTV silicone rubber, designed as a 25 Shore A Soft grade material with high extensibility & mechanical strength.Ultrasil has a Blue coloured catalyst to make processing easier by showing when the two components are thoroughly mixed.

Good product for taking molds from items with moderate undercuts.

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
