Dow Corning® 3055 resin reportedly allows manufacturers of high-performance coatings to formulate low-VOC, next-generation polysiloxane coatings with urethane, epoxy, polyester, alkyd, amine and acrylic systems utilizing amine functionality. Unlike moisture-cured polysiloxanes, the resin does not require titanate/tin catalysts or ambient moisture to cure. As a result, it does not contribute to volatile byproducts that can cause film stress and adhesion loss.

Polysiloxane hybrid coatings formulated with the resin reportedly exhibited long-term flexibility and improved chemical, thermal, UV, corrosion, and moisture resistance compared to epoxy and two-component polyurethane systems. In addition, adding the resin can improve the chemical resistance and flexibility of polysiloxane coatings beyond that of a traditional epoxy topcoat.
