Title (EN) AQUEOUS COATING COMPOSITION AND COATING FILM
(FR) COMPOSITION AQUEUSE DE REVÊTEMENT ET FILM DE REVÊTEMENT
(JA) 水性被覆組成物及び塗膜
Abstract:
(EN) Provided are an aqueous coating composition and a coating film that are capable of achieving an even higher level of both contamination resistance and weathering resistance. The aqueous coating composition includes a polymer emulsion (α) and an aqueous polymer (β), namely: (α) a polymer emulsion which includes an organosiloxane polymer block (I) having a specific organosiloxane unit and a polymer block (II) of an ethylenically unsaturated monomer; and (β) an aqueous polymer which is a copolymer formed from 40 mol% to less than 100 mol% of one type of ethylenically unsaturated monomer having an amide group and/or an amino group and more than 0 mol% to 60 mol% of at least one type of other ethylenically unsaturated monomer, a homopolymer formed from one type of ethylenically unsaturated monomer having an amide group and/or an amino group, or a copolymer formed from at least two types of ethylenically unsaturated monomers having an amide group and/or an amino group. In addition, the coating film includes a binder component and inorganic particles having an average particle size of 100 nm or smaller, the area occupied by the inorganic particles in the coating film surface being no larger than 49.9% and the average domain size of the inorganic particles being at least 500 square nanometers.
(FR) La présente invention concerne une composition aqueuse de revêtement et un film de revêtement dont la résistance à la contamination et la résistance aux intempéries sont élevées. La composition aqueuse de revêtement comprend une émulsion de polymère (α) et un polymère aqueux (β), à savoir : (α) une émulsion de polymère qui comprend une séquence polymère d'organosiloxane (I) contenant un motif d'organosiloxane spécifique et une séquence polymère (II) d'un monomère à insaturation éthylénique; et (β) un polymère aqueux qui est un copolymère formé de 40 % en mole à moins de 100 % en mole d'un type de monomère à insaturation éthylénique contenant un groupe amide et/ou un groupe amino et plus de 0 % en mole à 60 % en mole d'au moins un type de monomère à insaturation éthylénique différent, un homopolymère formé à partir d'un type de monomère à insaturation éthylénique contenant un groupe amide et/ou un groupe amino, ou un copolymère formé à partir d'au moins deux types de monomères à insaturation éthylénique contenant un groupe amide et/ou un groupe amino. De plus, le film de revêtement comprend un composant liant et des particules inorganiques ayant une taille moyenne de particule inférieure ou égale à 100 nm, la zone occupée par les particules inorganiques dans la surface du film de revêtement n'étant pas supérieure à 49,9 % et la taille moyenne de domaine des particules inorganiques étant au moins de 500 nanomètres carrés.
