Disclosed is a plasticizer for an adhesive composition, a coating composition, and a sealant composition that is applied or stuck to asphalt. In the present specification, an asphalt-containing substrate having an adhesive composition, a coating composition, or a sealing composition applied or pasted on the surface of the substrate, and an adhesive composition, a coating composition, or a sealing composition. Is disclosed. The composition suppresses softening of the asphalt compound of the asphalt-containing substrate at a high temperature, and includes one or more bases and one or more plasticizers. The plasticizer is a low molecular weight compound and preferably comprises an ester-containing reaction product of one or more glycerol and one or more carboxylic acids or an ester-containing reaction product of a glycol and an aryl carboxylic acid. The base of the above composition is preferably a polymer or copolymer such as polyurethane, silylated polyurethane, silylated polyether, copolymers thereof, and blends thereof. In addition, the present specification also discloses a product including the above composition and a method of applying or sticking the above composition to a substrate. [Selection figure] None |
