Title (EN) METALLIC COATING COMPOSITIONS
(FR) COMPOSITIONS MÉTALLIQUES DE REVÊTEMENT
Abstract:
(EN) A pigment-containing coating formulation combines (i) polymeric wetting and dispersing additives that absorb onto pigment particles to surround pigment particles to prevent or limit sedimentation; (ii) a self-crosslinking acrylic dispersion with low surfactants and long open time, allowing the pigment to lay flat instead of migrating and agglomerating at the surface; and (3) rheology modification facilitating good Newtonian flow behavior and balanced thixotropic thickening of the coating for improved brushability, flow and leveling for improved appearance with keener light reflection and more uniform pearlescent and metallic effect appearance.
(FR) La présente invention concerne une formulation de revêtement contenant un pigment dans laquelle sont combinés (i) des additifs polymères de mouillage et de dispersion qui sont absorbés sur des particules de pigment pour entourer les particules de pigment afin de prévenir ou de limiter la sédimentation; (ii) une dispersion acrylique d'auto-réticulation ayant une faible teneur en tensioactifs et un long temps d'ouverture, permettant au pigment de rester à plat au lieu de migrer et de s'agglomérer sur la surface; et (3) la modification de rhéologie facilitant un bon comportement d'écoulement newtonien et un épaississement thixotrope équilibré du revêtement pour une aptitude améliorée à l'application au pinceau, à l'écoulement et au nivellement, ce qui permet d'obtenir une apparence améliorée avec une réflexion de lumière plus intense et une apparence à effet nacré et métallique plus uniforme.
