Bayhydrol UV VP LS 2317 Urethane acrylate Bayer MaterialScience Polyurethane (PU) - Polyurethane dispersions (PUDs) Coatings >> UV / Radiation Curing Coatings >> Waterborne Wood & Furniture Coatings water Bayhydrol UV VP LS 2317 is a cosolvent free urethane acrylate dispersion used in the formulation of physically drying aqueous UV-curing coatings. These are characterized by their good reemulsification properties and high wet film transparency. Form supplied is approximately 37% dispersion in water. Bayhydrol UV VP LS 2317 is used in the formulation of aqueous UV-curing coatings, especially for application on wood/wood materials. Generally speaking, the coated surfaces can be sanded before UV curing. Additions of 1 - 2.5 % by wt. photoinitiator, calculated on the solid binder, have proven to be suitable for initiating the curing reaction. The viscosity is adjusted by the addition of polyurethane thickeners. If antifoams are used, they should be thinned in solvents, especially if application is by curtain coating. Matting agents and additives can be dispersed directly in the product using a dissolver. Bayhydrol UV VP LS 2317 is easily matted using standard matting agents. As a rule, the coatings should be colored using aqueous pigment pastes. Urethane acrylate dispersion. Used for wood coatings. Offers good reemulsification properties and high wet film transparency.
