Material Notes:
Description: Epolene C-18P is a branched low density polyethylene powder modified with maleic anhydride. It is useful as a base polymer for adhesives and coatings, color concentrate dispersion, and applications requiring compatibility with polyamide. Coatings produced with Epolene C-18P exhibit high gloss, low moisture vapor transmission rates, grease resistance, and good heat seal ability. In hot melt adhesives, the maleic anhydride modification allows for improved adhesion, greater filler tolerance, broader capabilities, and improved aging properties. Key Attributes: Enhances paraffin wax coating properties like gloss, grease resistance, and MVTRExcellent thermal stabilityMaleic anhydride grafted PE provides functionalityMedium molecular weightUseful in color concentrates Application/Uses: Automotive OEMmotive refinishmotiveBuilding and ConstructionHot Melt AdhesivesPackagingSolvent borne AdhesivesInformation provided by Westlake Chemical
