Product Description

Hydroxyl-modified vinyl chloride/vinyl acetate copolymers are noted particularly for compatibility with other film-forming resins, such as alkyds, urethane elastomers, isocyanate resins, epoxy polymers, and urea and melamine resins.Hydroxyl-modified vinyls are, therefore, often formulated with these and other film-forming materials to improve coating properties, such as adhesion, flexibility, toughness, hardness, and chemical resistance. Hydroxyl-modified resins are often used to impart snap-dry properties to a coating. The hydroxyl functionality permits crosslinking reactions for thermoset coating systems that exhibit outstanding chemical and water resistance. Coatings based on these resins also have good adhesion to wash primers, metals, wood, and many plastic substrates. VAH Solution Vinyl Resin A high molecular weight, partially hydrolyzed vinyl chloride/vinyl acetate resin having a composition of approximately *0 percent vinyl chloride, 4 percent vinyl acetate, with a hydroxyl content of approximately 2.3 percent; VAH solution vinyl resin can be dissolved in relatively strong solvent/diluent combinations, such as *0 percent ketone/*0 percent aromatic hydrocarbon, to produce resin solutions of *0 percent solids. VAH solution vinyl resin can be used for a wide range of coatings applications, including industrial maintenance and marine finishes, wood finishes, paper coatings, metal decorative and container coatings, and as a binder in magnetic tape.
