UNITHANE® 645 WD 57

Product overview
UNITHANE® 645 WD 57 is an urethane alkyd designed for use in clear and pigmented finishes. It can be used as the sole medium or in combination with long oil alkyds.UNITHANE® 645 WD 57 can be used in pigmented decorative gloss or eggshell finishes and should comprise between 20-50% of the media, the balance being a suitable long oil alkyd. UNITHANE® 645 WD 57 increases both hardness and abrasion resistance while maintaining excellent gloss retention. In thixotropic decorative gloss and eggshell finishes, similar percentages can be used. Abrasion resistant and rapid drying finishes are obtained, with the durability, pigment wetting and non-chalking characteristics of the alkyd resin being retained.For interior floor varnishes and related finishes, it is recommended that UNITHAN® 645 WD 57 be used as the sole binder.The low aromatic solvent in UNITHANE® 645 WD 57 allows coatings to be formulated which are exempt from European environmental labelling requirements.
