Baxenden at ECS: Exhibits Witcobond® PUDs, Trixene® Aqua Range of Crosslinkers and much more

Published on 2013-03-19. Author : SpecialChem

Baxenden Chemicals Ltd, a Chemtura Company, is a leading specialist in polyurethanes, urethane intermediates and polyurethane dispersion technology. It is exhibiting its latest Trixene® Aqua and Witcobond® product innovations for surface coatings from Stand 1-353 Hall 1 at the Nuremberg Exhibition Center, Germany, 19 - 21 March 2013.

The new Trixene® Aqua range of cross-linkers and adhesion promoters for waterborne coating formulations are 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 (e.g. 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.

Materials for field-applied coatings, membranes, sealants and adhesives, which are primarily used in the building and construction industries, for maintenance contracts etc. will be covered in a new Baxenden brochure for Trixene® and Quasilan® prepolymers, polyols and additives. They include aromatic and aliphatic prepolymers, flexibilizers for epoxies, moisture scavengers and bisoxazolidine curatives. Low monomer systems to meet current regulatory requirements on free isocyanate content will also be showcased.

The latest innovations in Witcobond® polyurethane dispersions (PUDs) are also featured. These materials are utilized in a multitude of waterborne coatings and finishes for hard and flexible substrates. The Witcobond® product range embraces anionic, cationic and nonionic chemistry, so binders covering the full pH range are available to the formulator. The extensive list includes high-solids content (60%) products, dispersions with low or no co-solvent (including NMP-free) and grades without APEO/NPEO or other surfactants. Recent developments include cationic PUDs for stain-blocking primers and dye lock-down, and co-solvent-free, hydroxyl-functional products for use in 2-K protective coatings on diverse surfaces.

The European Coatings Congress, organized in conjunction with the Exhibition is taking place from 18 - 19 March 2013 at the same venue. Dr. Jordana Todd, a Baxenden Research Associate, is presenting a paper entitled "Practical applications for heterocyclic ring-opening reactions in polyurethane technology" during Session 20: Construction Chemicals on Tuesday afternoon, 19 March 2013.
