Novel Non-Isocyanate Siloxane-Polyurethane Coatings (RFT-517)

Invention Summary

Glycidyl carbamate (GC) functional resins are used due to their high mechanical strength, toughness and abrasion and chemical resistance associated with polyurethanes as well as the convenience of epoxy-amine chemistry. Webster et al have combined these resins with polydimethylsiloxane to develop self-stratified coatings that yield coatings having low surface energy as well as reduce the hazards of isocyanates.

Benefits

Combines properties of polyurethanes with ease of epoxy-amine chemistry
Decreased hazards associated with isocyanates in current coatings
Excellent strength and adhesion with low surface energy
Improved durability and adhesion over silicone elastomers
Applications in marine ship hull coatings, anti-graffiti coatings, and anti-ice coatings

Technology

The technology is a siloxane-modified glycidyl carbamate resin and a coating composition utilizing amine crosslinkers.
