Westlake Epolene® C-19 Coating Grade - Highly Branched Medium Molecular Weight Polyethylene Polymer, Maleation Processed (discontinued **)
Categories:	Polymer; Thermoplastic; Polyethylene (PE)
Material Notes:	Product Description: Epolene C-19 is a branched low density polyethylene 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-19 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 MVTR Excellent thermal stability Maleic anhydride grafted PE provides functionality Medium molecular weight Application/Uses: Automotive OEM Building and Construction Hot Melt Adhesives Packaging Solvent borne Adhesives Color concentrates
