Title (EN) COATING COMPOSITION BASED ON A HYDROXY GROUP-CONTAINING FILM FORMING POLYMER, A POLYISOCYANATE COMPOUND, AND A DIOL
(FR) COMPOSITION DE REVETEMENT COMPORTANT UN POLYMERE FILMOGENE CONTENANT UN GROUPE HYDROXY, UN COMPOSE POLYISOCYANATE, ET UN DIOL
Abstract:
(EN) The invention relates to a coating composition comprising a hydroxy group-containing film forming polymer with a hydroxy value between 75 and 300 mg KOH/g solid resin, a polyisocyanate compound, and a diol of the general formula HO-CH2-CR(C2H5)-CH2-OH, wherein R is an alkyl group having 3-6 carbon atoms. The invention further relates to a method of coating which comprises said coating composition being applied to a substrate, and to a coated substrate, in particular cars and large transport vehicles.
(FR) L'invention concerne une composition de revêtement comprenant un polymère filmogène contenant un groupe hydroxy avec une résine solide dont l'indice hydroxy se situe entre 75 et 300 mg de KOH/g, un composé polyisocyanate et un diol dont la formule générale est HO-CH2-CR(C2H5)-CH2-OH. Dans cette dernière, R représente un groupe alkyle comportant 3 à 6 atomes de carbone. L'invention a aussi pour objet un procédé de revêtement qui consiste à appliquer cette composition de revêtement à un substrat. L'invention traite également d'un substrat ainsi recouvert, en particulier, des voitures et des véhicules de grande taille.
