Abstract

PURPOSE: The titled paint that is composed of a specific polyester copolymer and an amino resin, thus being suitably used as a precoating paint for steel plates primed with an epoxy paint, because of its giving good balance between hardness and processability.
CONSTITUTION: The objective paint comprises (A) 55W95wt% of copolyester which is made from (i) the acid component composed of terephthalic acid (70W 95mol%), 6W36C aliphatic carboxylic acid (30W5mol%) and other mono- or dicarboxylic acids (0W10mol%) and (ii) the polyol component composed of ethylene glycol (30W70mol%) and neopentyl glycol (70W30mol%), having 0.3W 1.0dl/g reduced viscosity (ηsp/C) and containing more than 50% equivalent of hydroxyls based on the total equivalent of carboxyl and hydroxyl groups and (B) 45W10wt% of an amino resin. The resultant paint is used as a precoating paint for steel plates primed with an epoxy resin.
