Reacted with polyisocyanate, water based hydroxyl acrylic dispersion can produce the same hardness, impact resistance and solvent resistance as solvent based polyurethane coating. PU coating made of WL-153 is recommended to use in topcoat of metal or wood due to its paint film has excellent gloss, the construction method can be brushing, roll coating or spraying.
This two component PU resin WL-153 is recommended to be used in place of Bayer A145 due to its similar properties with Bayer A145.
