Abstract: A hot melt adhesive (HMA), which is solid at room temperature, comprises the reaction product of 5 to 25% by weight of an isocyanate component having an NCO content of from about 20 to about 50% by weight, 75 to 85% by weight of a polyester, and 1 to 10% by weight of a hydroxy-polymer having an OH number of from about 40 to about 50. A method of forming the adhesive comprises the step of combining the isocyanate component, polyester, and hydroxy-polymer to form the adhesive. The adhesive can be used for various purposes, such as for forming an adhesive layer which adhesively couples surfaces together.
