4040

Winlex4040 is a semi-solid rosin ester with good stability and mild odor. It is easily emulsified in water by conventional means. 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. The principal uses for this resin are in the formulation of oil varnish, lacquer, hot-melt, heat-sealing, and pressure-sensitive adhesives. It has a suitable FDA status for use in food packaging applications covered by 175.105.

FEATURES

Soluble in Aromatic and aliphatic hydrocarbon solvents, esters, ketones and chlorinated solvents.  Insoluble in alcohol and water.

Compatible with Ethylene Vinyl Acetate (EVA) polymers, Ethylene Ethyl Acrylate, Styrene-Isoprene-Styrene (SIS), Styrene-Butadiene-Styrene (SBS), SBR, natural rubber, butyl rubber, neoprene, acrylic polymers, amorphous polypropylene, alkyds, hydrocarbon resins and terpene resins. 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.

SUGGESTED APPLICATIONS

Winlex4040 is recommended for a variety of pressure sensitive and hot melt applications, especially where its low glass transition temperature contributes more aggressive tack and better low temperature properties. It is readily emulsifiable for use in water-based systems. Its low solution viscosity and low volatility suggest uses as a plasticizer or coupling agent in lacquers and high solids coatings.
