Dow Corning offers 3055 resin for low VOC polysiloxane coatings

October 10, 2012

With Dow Corning 3055 Resin, manufacturers of high-performance paints and coatings can formulate low-VOC, next-generation polysiloxane coatings with urethane, epoxy, polyester, alkyd, amine and acrylic systems utilizing amine functionality, according to the company. Unlike moisture-cured polysiloxanes, Dow Corning 3055 Resin does not require titanate/tin catalysts or ambient moisture to cure. As a result, Dow Corning 3055 Resin does not contribute to volatile by-products that can cause film stress and adhesion loss. Polysiloxane hybrid coatings formulated with The company reports that Dow Corning 3055 Resin have exhibited long-term flexibility and improved chemical, thermal, UV, corrosion and moisture resistance compared to epoxy and two-component polyurethane systems. Most notably, adding Dow Corning 3055 Resin improves the chemical resistance and flexibility of polysiloxane coatings beyond that of a traditional epoxy topcoat. Compared to two-component polyurethane coatings, polysiloxane coatings with Dow Corning 3055 Resin have similar physical properties - but with better corrosion resistance.
