    Features & Benefits

    Features
    • Low odor and excellent stability.
    • Soluble in esters, petroleum benzine, mineral spirit, benzene, ethyl acetate, acetone aliphatic and chlorinated solvents. Insoluble in ethanol and water. Compatible with NR, SBR, EVA210 and EVA420. Its polymer compatibility allows it to be used as a tackifier/plasticizer in many adhesive systems, particularly where better wetting or low temperature tack is required.

    Applications & Uses

    Suggested Applications
    • A tackifier for adhesive. It is also used as plasticizer or modifier for hot melt adhesive.
    • When mixed with non-crystallization rosin Fintac2331, Winlex4270 can be used in water-based flooring adhesives.
    • Itis readily emulsifiable for use in water-based systems.
