PURPOSE:To obtain a one-pack chloroprene adhesive having excellent adhesive power and heat resistance, by mixing a chloroprene rubber modified with an isocyanatosilane with a tackifier resin and an organic solvent. CONSTITUTION:The title adhesive consists of a chloroprene rubber modified with an isocyanatosilane, a tackifier resin, and an organic solvent. Examples of the isocyanatosilane include gamma-isocyanatopropyldimethylchlorosilane and gamma-isocyanatopropyltriethoxysilane. An isocyanatosilane can also be obtained by the reaction of a polyisocyanate with a silane having functional groups active to an isocyanate group (e.g., an aminosilane, mercaptosilane or epoxysilane). As the tackifier resin, a chelation product made from an alkyl phenolic resin and a metallic oxide is preferably used.
