ZA RTV 20-45 YELLOW Addition-Curing Silicone Rubber for Moulds, Shore A 20

ZA RTV 20-45 YELLOW is a pourable, addition-curing, two-component yellow silicone rubber for flexible moulds that vulcanizes at room temperature. Excellent resistance to polyester, epoxy or polyurethane casting resins. Shore A 20 hardness.

Special feature

• Low viscosity
• High tear strenght
• Durability
• Excellent long term stability of the mechanical characteristics of the hardened rubber

Application

• Mold making is especially suitable for all the models with extensive undercuts that are to be reproduced in casting resins. Low viscosity, dimensional stability, precision in reproduction, high mechanical resistance, durability.
• Artificial Stone (good compatibility with concrete formulas).
• Concrete Moulding (good compatibility with concrete formulas).

Processing

Important note: the platinum catalyst is in the component CATALYST.

Catalyst and Base components may only be used together if they have the same batch number.
