An adhesive composition based on resorcinol novolac or resorcinol-phenolic novolac contains 35-75% by weight of novolac, less than 25% by weight of water, and 10-40% by weight of an aliphatic divalent, trivalent alcohol. The adhesive composition may also contain up to 20% by weight of filter, based on the amount of novolac, water and alcohol. In a method for preparing the adhesive composition based on resorcinol novolac or resorcinol-phenolic novolac, the novolac is produced by conventional condensation, whereupon an aliphatic divalent, trivalent or tetravalent alcohol is added and water in the novolac is distilled off, resulting in an adhesive composition as defined above. Alternatively, the amount of water can be reduced in the condensation of the novolac to be replaced with an aliphatic divalent, trivalent or tetravalent alcohol.

Adhesive composition based on novolac

An adhesive composition based on resorcinol novolac or resorcinol-phenolic novolac consisting essentially of 35-75% by weight of novolac, less than 25% by weight of water, and 10-40% by weight of an aliphatic divalent, trivalent or tetravalent alcohol. The adhesive composition may also contain up to 20% by weight of filler, based on the amount of novolac, water and alcohol.

Alternatively, the amount of water can be reduced in the condensation of the novolac to be replaced with an aliphatic divalent, trivalant or tetravalent alcohol.
