DOWSIL 7

DOWSIL 7 also known as Dow Corning 7 is a polydimethylsiloxane polymer. 

Applications: Rubber industry: Lubricant and preservative for tight fitting parts: They slide into place quickly and easily, for difficult release jobs, e.g. battery cases. Plastic industry: Release agent for epoxy resins, polystyrenes, PVC, polyesters and other plastic materials. Foundry and smelting industries: Breaking-in of new or freshly cleaned shells, for core molds. Other industries: Release agent for TNT, rocket propellants, ram heads and other parts of extruders, Release agent in forming integral seals for clay tiles. 

Features: Heat stable; Withstand molding temperatures up to +200°C; Minimizes build up on molds due to heat stability and resistance to oxidation; Efficient low quantities required; Inert to metals and most plastic and organic materials; Insoluble in water, methanol, ethanol, glycerol, and mineral oil. 

Composition: Silicone oil; Inorganic thickener.
 
Temperature Range: From -40 to +200°C
