摘要：Crosslinkable thermoplastic adhesive composition exhibiting, inter alia, theadvantage of being oil-permeable, permitting its use in many fields, in particular in thefield of adhesive bonding to greasy sheet metal. The adhesive composition according tothe invention is based on hydroxytelechelic polybutadiene and a mixture of diisocyanatecompounds. It contains, per 100 parts by weight of hydroxytelechelic polybutadiene, aquantity of tolylene diisocyanate and a quantity of isophorone diisocyanate such that theratio of the total number of isocyanate functional groups of the composition to the totalnumber of hydroxyl functional groups of the composition is between 0.90 and 1.30. Theratio of the number of the isocyanate functional groups contributed by tolylenediisocyanate to the number of isocyanate functional groups contributed by isophoronediisocyanate is between 0.1 and 2. The catalyst employed is chosen from the groupconsisting of tertiary amines and organic lead or tin salts and is introduced into thecomposition of the mixture in a proportion of 0.1 to 1% by weight in the case of a tertiaryamine and in a proportion of 0.01 to 0.1% by weight in the case of a metal salt.
