Chemical Structural Formula

Product Overview

The polydimethylsiloxane compound with hydroxymethyl as the terminal functional group can be used as a modifying component in various resin systems such as polyester and epoxy. The hydroxyl groups in its molecular structure can participate in the resin cross-linking reaction, introducing organic silicon components into the resin system (especially the surface area), thereby significantly enhancing the key performance of the paint film, such as weather resistance, long-lasting feel, stain resistance, and low-temperature resistance.
