Another emphasis is on conventional PU systems with very low MDI and TDI contents that meet new regulatory requirements. Low monomer products are suitable for a broad spectrum of applications, ranging from adhesives to 2-K membrane coatings. Materials offered for general coatings include a wide range of aromatic and aliphatic prepolymers, moisture scavengers, and oxazolidine developments. New developments in the Witcobond range of polyurethane dispersions (PUDs) are also highlighted. These materials are used in aqueous coatings and finishes for hard and soft substrates. The range includes high-solids products, dispersions with low or no cosolvent (including NMP-free), and grades without APEO/NPEO 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.
