High strength silicone moldmaking rubber.

• Outstanding release properties
• If required the product cure can be heat accelerated
• Fast thick section cure at room temperature

• Very high elasticity, for easy removal of complex replica parts
• Very low shrinkage and good dimensional stability

SILASTIC S is a two-component material consisting of SILASTIC S Base, which when mixed with the SILASTIC S Curing Agent cures at room temperature by an addition reaction.

A range of materials can be cast into the cured silicone mold:plaster, polyurethane, polyester and other reactive resins are materials typically used.

SILASTIC S can be used for high temperature casting applications or can be made thixotropic (nonflowable) for vertical surface replication

Typical cure time: 7 hours
