METHOD OF IMPROVING BLOCK RESISTANCE OF ADHESIVE COMPOSITIONS

摘要

A method is disclosed for improving the block resistance of adhesive compositions containing at least one polyamide resin including the steps of: (1) forming an adhesive composition containing a polyamide resin which is the reaction product of: (a) an acid component of from: (i) about 10 to about 80 equivalent % of a polymeric fatty acid; and (ii) about 10 to about 95 equivalent % of a dicarboxylic acid; and (b) a substantially equivalent amount of an amine component of from: (i) about 60 to about 95 equivalent % of a cycloaliphatic diamine; and (ii) greater than about 0 to less than about 20 equivalent % of ethylenediamine; and (2) applying said adhesive composition to a first substrate; and (3) adhering said first substrate to a second substrate at a heat seal temperature less than about 300 ~F.
