Accrington, UK -- Baxenden says that at the European Coatings Show in Nuremberg next week, its bold new exhibition stand will present the latest developments in Trixene blocked isocyanates from its Urethane Surface Coatings Division. These products include new water-based blocked crosslinkers for applications such as OEM-type, heat-cure coatings and adhesion treatments for industrial processes, for example fibre reinforcement.
Another emphasis at Baxenden's stand will be on conventional PU systems with very low levels of MDI (methylene diphenyl diisocyanate) and TDI (toluene diisocyanate), that the company says are needed to meet new regulatory requirements.
Such low-monomer products are suitable for a broad spectrum of applications, ranging from adhesives to 2-K membrane coatings, Baxenden said
Materials offered for general coatings include a wide range of aromatic and aliphatic prepolymers, moisture scavengers and oxazolidine developments.
Also on display will be the latest developments in the Witcobond range of polyurethane dispersions (PUDs). These materials are used in a multitude of aqueous coatings and finishes for hard and soft substrates, says Baxenden.
According to Baxenden, the extensive range includes high-solids products, dispersions with low or no co-solvent (including ones free of N-methylpyrollidone, NMP), and grades without APEO/NPEO (alkylphenol or nonylphenol ethoxylates) or other surfactants.
PUD chemistries embrace: anionic, nonionic and cationic systems providing for wide pH tolerance; fully-reacted polymers for 1-K formulations; hydroxyl-functional urethanes for 2-K coatings; and latent-curing mechanisms.
Further details of these PUD applications can be seen on a new dedicated website, www.witcobond.com
Baxenden, a Chemtura unit, will be exhibiting on stand 116 in hall 8 at the European Coating Show, which is being held in Nuremberg, Germany, 29- 31 March 2011.
