Chemtura leads formulation innovation with Trixene and Witcobond products at ACS

Chemtura Corporation will be exhibiting its latest Witcobond aqueous polyurethane dispersions and Trixene Aqua blocked isocyanates product innovations for surface coatings at the American Coatings Show, Stand 1049, at the World Congress Center in Atlanta, GA on April 8-10 2014.

The new Trixene® Aqua range of crosslinkers and adhesion promoters for waterborne coating formulations will be highlighted. These products are blocked isocyanate dispersions, for use in 1-K and 2-K systems with complementary aqueous resins, e.g. hydroxyl-functional acrylics, polyesters and urethanes. They augment the current portfolio of Trixene® solvent-based blocked isocyanates for OEM oven-cure coatings (eg automotive, coil, electrodeposition), textile coating & finishing and various heat-bonding applications. Trixene® technology focuses on blocked isocyanates containing 3,5-dimethylpyrazole (DMP) as a lower energy crosslinking system that helps reduce curing temperatures and/or improve throughput.

The latest innovations In Witcobond® polyurethane dispersions will also be featured. The Witcobond® range embraces anionic, cationic and nonionic chemistry, so aqueous polyurethane film formers covering the full pH range are available to the formulator. The extensive list includes high-solids content (60%) products, dispersions no cosolvent (including NMP-free) and grades without APEO/NPEO or other surfactants. Recent developments include cationic dispersions for stain-blocking primers and dye lock-down, and cosolvent-free, hydroxyl-functional products for use in 2-K ambient cure and 1K heat cure coatings on diverse substrates.

The American Coatings CONFERENCE 2014, organised in conjunction with the Exhibition will take place from April 7-9 2014 at the same venue. Ms Kirstie Rawlinson, Chemtura’s Urethane Surface Coatings Section leader, will be presenting a paper entitled ‘Latent Polyisocyanate Crosslinkers for Aqueous Functional Resins’ during Session 10: Polyurethanes II, on Tuesday afternoon, April 8, 2014.
