Abstract
(EN)
The present invention provides a moisture-curable polyurethane hot melt resin composition which contains a urethane prepolymer (i) that has an isocyanate group and uses a polyol (A) and a polyisocyanate (B) as starting materials, and which is characterized in that: the polyol (A) contains an aliphatic or alicyclic polyester polyol (a1) that uses adipic acid as a starting material, and an aromatic polyester polyol (a2); and the used amount of the polyester polyol (a1) is larger than the used amount of the aromatic polyester polyol (a2). It is preferable that the amount of urethane bonds in the urethane prepolymer (i) is within the range of from 0.5 mol/kg to 3 mol/kg.
(FR)
La présente invention concerne une composition de résine thermofusible de polyuréthane durcissable à l'humidité qui contient un prépolymère d'uréthane (i) qui présente un groupe isocyanate et utilise un polyol (A) et un polyisocyanate (B) en tant que matières premières et qui est caractérisée en ce que : le polyol (A) contient un polyester-polyol aliphatique ou alicyclique (a1) qui utilise de l'acide adipique en tant que matière première et un polyester-polyol aromatique (a2) ; et la quantité utilisée du polyester-polyol (a1) est supérieure à la quantité utilisée du polyester-polyol aromatique (a2). Il est préférable que la quantité de liaisons uréthane dans le prépolymère d'uréthane (i) soit située dans la plage de 0,5 mole/kg à 3 moles/kg.
