SILASTIC™ RTV-4260-V Base and Curing Agent is a high strength silicone rubber featuring medium durometer, low mixed viscosity, suited for the reproduction of architectural, furniture components and prototypes. It is recommended for use with rigid and foam polyurethane and can be used with polyester, cement and plaster.
Features and Benefits:- Outstanding release properties, high mold life for casting of polyurethane (both foam and rigid)
- Very low shrinkage and good dimensional stability
- Very high tear resistance
- High elasticity, for easy removal of complex replica parts
- Medium mixed viscosity and medium hardness
- If required the product cure can be heat accelerated
- Can be made thixotropic (nonflowable) for vertical surface replication
