| description | Provided is a two-pack type clear coating composition capable of forming a clear coating film that is easily sanded while being superior in scratch resistance. A two-pack type clear coating composition including a base agent (A) and a curing agent (B), wherein the base agent (A) includes a first hydroxy group-containing acrylic resin having a hydroxyl value of 120 mg KOH/g or less and a second hydroxy group-containing acrylic resin having a hydroxyl value of more than 120 mg KOH/g, the curing agent (B) includes an isocyanate compound, and a coefficient of dynamic friction of a surface of a coating film obtained from the two-pack type clear coating composition is 0.35 or more under a load of 50 g.
L'invention concerne une composition de revêtement transparent à deux composants, capable de former un film de revêtement transparent qui présente une excellente résistance aux rayures mais qui est facilement poli. L'invention porte sur une composition de revêtement transparent à deux composants contenant un agent principal (A) et un agent de durcissement (B), l'agent principal (A) contenant une première résine acrylique à teneur en groupe hydroxyle ayant un indice d'hydroxyle de 120 mg KOH/g ou moins et une seconde résine acrylique à teneur en groupe hydroxyle ayant un indice d'hydroxyle de plus de 120 mg KOH/g, l'agent de durcissement (B) contenant un composé isocyanate, et le coefficient de frottement dynamique d'une surface de film de revêtement obtenue à partir de la composition de revêtement transparent à deux composants étant de 0,35 ou plus à une charge de 50 g. |
