Dow Corning® Offers 3055 Resin to Help Formulate Low VOC Polysiloxane Coatings

Published on 2012-09-27. Author : SpecialChem

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."

Dow Corning offers a comprehensive selection of innovative silicon-based additives, resins and binders for the coatings industry. In addition to materials, the company provides supportive services and solutions tailored to the specific business needs of the global coatings industry.
