AIR DRYING COATING COMPOSITION OF AN ACRYLIC AND ALKYD POLYMER BLEND AND A POLYISOCYANATE

摘要

TITLE Improved Air Drying Coating Composition of an Acrylic and Alkyd Polymer Blend and a Polyisocyanate A coating composition that contains as the film-forming binder an acrylic vinyl oxazoline polymer, an alkyd resin and an additive of a polyisocyanate of the formula < IMG > where R7 is a hydrocarbon group having six carbon atoms; ultraviolet light stabilizers, an organic solvent and optionally a plasticizer; this composition cures rapidly at ambient temperatures to a tough, durable, weatherable, scratch resistant and gasoline resistant finish particularly useful for repairing finishes of automobiles or trucks.
