Polyfunctional alcohol modified carboxylic acid esterified polyolefin

Polyfunctional carboxylic acid esterified polyolefins used as adhesion promoters in coatings, inks, and adhesives

The subject polyolefins used as adhesion promoters in solvent-borne and aqueous primer compositions and adhesive formulations contain polyolefins esterified with ≥1 carboxylic acid (polyolefins with a heat of fusion of 0 to 10 cal/g The reaction product formed with ≥1 polyfunctional alcohol. For example, a reaction product formed of 138.9 parts of maleic acid Eastoflex E 1200 (propylene mono ethylene copolymer) and 1.7 parts of trimethylol ethane is spray-coated on a thermoplastic olefin decorative board and then cured with Durethane 802 (OEM melamine) The primers) and UCC 1001 (varnish) are applied to form a coating with good gasoline resistance, moisture resistance, and adhesion.
