Abstract | Disclosed is an aqueous primer composition essentially containing a water-dispersible polyisocyanate (A) and an aqueous acrylic resin dispersion (B). The weight average molecular weight of the acrylic resin in the aqueous acrylic resin dispersion (B) in terms of polystyrene, which is determined by gel permeation chromatography, is not less than 350,000, and the glass transition temperature of the acrylic resin determined by differential scanning calorimetry is 15-130°C. The weight ratio between the water-dispersible polyisocyanate (A) and the aqueous acrylic resin dispersion (B) is from 70:30 to 50:50 in terms of solid content.
Il est divulgué une composition de primaire aqueux contenant essentiellement un polyisocyanate hydrodispersable (A) et une dispersion de résine acrylique aqueuse (B). Le poids moléculaire moyen de la résine acrylique dans la dispersion de résine acrylique (B) en termes de polystyrène qui est déterminé par chromatographie par perméation de gel n'est pas inférieur à 350,000, et la température de transition vitreuse de la résine acrylique déterminée par la calorimétrie différentielle à balayage est comprise entre 15 et 130°C. Le rapport pondéral entre le polyisocyanate hydrodispersable (A) et la dispersion de résine acrylique aqueuse (B) est compris entre 70:30 et 50:50 en termes de contenu solide. |
