Foam adhesion promotion

A method for forming a thermoplastic elastomer (TPE)-skinned composite comprising the steps of:

• a) forming a skin layer having at least one surface comprising:
• (i) a thermoplastic elastomer wherein the thermoplastic elastomer has at least one glass transition temperature below 25° C., has an elongation of at least 50% as measured according to ISO 37, and has a tensile strength of at least 4 MPa as measured according to ASTM D412;
• and
• (ii) an adhesive promoting agent wherein said adhesive promoting agent comprises diethanol amine amide (DEAA) having the following structure:
• wherein R is a hydrocarbon chain, saturated or unsaturated, containing 6-18 carbon atoms wherein DEAA is present at a level of 0.5 wt. % to 5.0 wt. % based upon the total weight of the skin layer;
• b) providing a foam layer forming mixture on the at least one surface of the skin layer;
• c) forming a foam layer on the at least one surface of the skin layer to form the TPE-skinned composite.
