Laromer LR 8949 Aliphatic polyurethane BASF Polyurethane (PU) - Polyurethane dispersions (PUDs) Coatings >> UV / Radiation Curing Wood & Furniture Coatings Plastic coating water Aqueous radiation-curable polyurethane dispersion with physical-drying properties for the manufacture of varnishes for wood, wood products and plastics Aqueous radiation-curable polyurethane dispersion Laromer LR 8949 is a physically drying radiation-curable aliphatic PUR dispersion for the coating of wood, wood products and plastics. It can be combined with suitable conventional dispersions (eg, the pure acrylic dis-persion Acronal A 846) to improve drying of the coating before UV curing. Curtain coating and spraying are the preferred application techniques for coatings based on Laromer LR 8949. After UV curing, the coatings exhibit excellent resistance to water and chemicals as well as very good scratch resistance and resistance to blocking. Laromer LR 8949’s very good grain-enhancement properties on wood is a distinct advantage. Thickeners and defoamers are often included in the formulation. To pre-vent precipitation or separation, these materials should be predispersed with binder, wetting agent and water before being added. Matting agents can be similarly incorporated. Aqueous physically drying radiation-curable aliphatic PUR dispersion. Used for manufacture of varnishes for wood, wood products and plastics. Can be combined with conventional dispersions such as pure acrylic dispersion to improve drying. Provides very good resistance to water and chemicals, very good scratch resistance, resistance to blocking and very good grain-enhancement properties.
