Silway 680 is a long-chain alkylaralkylpolysiloxane. Compared to the traditional polydimethylsiloxane, Silway 680 has many excellent properties. Used as release agent, Silway 680 is suitable for soft metal (aluminum, zinc, magnesium, etc.) on die casting. The surface of the product is bright, and Silway 680 is not carbonated on the mold surface. Silway 680 does not affect the secondary printing and finishing.
