Product Information Sheet

Characteristics

Vinisol OH03 is a ter-polymer resin of vinyl

chloride, vinyl acetate, and hydroxy-proply acrylate

(HPA), produced using a solution polymerization

process. The resin is intended for use in a solvent or

mixture of solvents. The resin is treated using a

proprietary process to remove all low molecular

agents following polymerization, so a solution of the

resin is free of the insoluble particles (“seeds”) .

Vinisol OH03 is a cost effective alternative to OH

functional vinyl resins produced via a solution

polymerization process, and can be used in most

applications with little or no modification of the

solution formula. Vinisol OH03 resin has medium

molecular weight, fine particle size, and high bulk

density. Vinisol OH03 can be formulated with

components that will react with the available –OH on

the polymer, to form solvent resistant films and

coatings. Cross-linked films also display improved

toughness and tensile strength; typical improvements

in tensile strength are 10% to 20% compared to noncross-

linked films. The polymer reacts at room

temperature with urethane (isocyanate) prepolymers,

and reacts at elevated temperatures (baked cure) with

urea or melamine pre-polymers. The curing of baked

systems is accelerated by an acid catalysts such as

n-butyl phosphoric acid. The resin has excellent

solubility in conventional ketone/toluene and

ketone/xylene solvent mixtures, and improved

tolerance for alcohols due to it’s –OH functionality.

Vinisol OH03 produces films that are more resistant

to light and weathering than conventional vinyl

resins. Other physical properties (color, heat

stability, solution viscosity, etc.) are similar to

conventional vinyl solution resins.
