High Strength Two-Part RTV Polyurethane Liquid Rubber 45 Shore A
For Making Molds
Description:
Polyurethane rubber consists of A&B component, which, after
mixing, cure at room temperature to flexible, high-strength, mold
rubber. It can make durable molds for casting plasters and waxes,
cement.
Characteristics:
It has excellent processing properties, solid in common
temperature, shorter gel time, and regulating color by adding
pigment. The ware has good properties of abrasive resistance,
hydrolysis resistance, transparent, good resilience, stable
dimension.
Application:
Suitable for making the mould for concrete panel, trims & cultured
artificial stone veneer, resin crafts, etc.
