Siloxane Resin optimizes chemical resistance of coatings.

Press Release Summary:

With Dow Corning® 3055 Resin, manufacturers can formulate low-VOC polysiloxane coatings with urethane, epoxy, polyester, alkyd, amine, and acrylic systems utilizing amine functionality. Liquid crosslinking resin does not require titanate/tin catalysts or ambient moisture to cure, and does not contribute to volatile by-products that can cause film stress and adhesion loss. Coatings formulated with Dow Corning® 3055 exhibit optimized chemical, thermal, UV, corrosion, and moisture resistance.

New Amine-Functional Siloxane Resin for Next-Generation Polysiloxane Coatings

Low-VOC, liquid crosslinking resin improves the thermal, weather, chemical and corrosion resistance of high-performance paints and coatings

MIDLAND, MICHIGAN, USA: 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.

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 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, demonstrating true synergy.

Furthermore, compared to two-component polyurethane coatings, polysiloxane coatings with Dow Corning® 3055 Resin have similar physical properties – but with better corrosion resistance. With such improved performance, there is the potential to use a two-coat polysiloxane system instead of the three-coat system needed with a two-component polyurethane topcoat, which means reduced labor costs and faster return-to-service.

“We are excited about Dow Corning® 3055 Resin because it can be used in a wide variety of protective coating applications,” said Jim Stange, Dow Corning’s North America Market Manager, Coatings. “What makes Dow Corning® 3055 Resin especially intriguing is the potential utility for performance improvement in applications outside of traditional protective coatings, such as fire-resistant and intumescent coatings, composite polymers, industrial adhesives, and high-temperature coatings.”
