Abstract
(EN)
This resin composition for a sealant contains: a resin (A) which is an ethylene(meth)acrylic acid ester copolymer containing 10-25 mass% of a (meth)acrylic acid ester unit; and an adhesiveness-imparting resin (B). The content of the resin (A) exceeds 45 mass% with respect to the total amount of the resin component of the resin composition for a sealant, and the content of the adhesiveness-imparting resin (B) is 0.1-10 mass% with respect to the total amount of the resin component of the resin composition for a sealant.
(FR)
L’invention concerne une composition de résine destinée à un agent d'étanchéité contenant : une résine (A) qui est un copolymère d'ester d'acide (méth)acrylique d'éthylène contenant de 10 à 25 % en masse d’un motif ester d'acide (méth)acrylique ; et une résine conférant une propriété adhésive (B). La teneur en résine (A) dépasse les 45 % en masse par rapport à la quantité totale du constituant de résine de la composition de résine destinée à un agent d'étanchéité, et la teneur en résine conférant une propriété adhésive (B) est de 0,1 à 10 % en masse par rapport à la quantité totale du constituant de résine de la composition de résine destinée à un agent d'étanchéité.
