SILASTIC™ RTV-4251-S2 Kit
Silicone Rubber(硅橡胶)
陶氏化学(Dow Chemical)
产品描述
High strength silicone moldmaking rubber
Features & Benefits
• Outstanding release properties • Low viscosity allowing easy mixing and degassing • Fast thick section cure at room temperature • If required the product cure can be heat accelerated • Medium hardness • High tear resistance • Very high elasticity, for easy removal of complex replica parts • Very low shrinkage and good dimensional stability • Can be used for high temperature casting applications • Can be made thixotropic (nonflowable) for vertical surface replication
Applications
• SILASTIC™ RTV-4251-S2 Kit is suited for detailed reproduction of surfaces and objects, particularly suited for reproductions in plaster, polyurethane and concrete.
