Viscosity modifier for plastisol composition, plastisol composition, and product and molded article each obtained therefrom
View Patent ↗A viscosity modifier for plastisol compositions which contains at least one selected from the group consisting of: (A) a compound having at least one of a carboxy group or a salt thereof, an alkoxy group, and a glycidyl group; (B) amine compounds; and (C) metal chelate compounds. A plastisol composition containing the viscosity modifier and a polymer. A product having a coating layer obtained from the composition. A molded product obtained by using the composition. This viscosity modifier has an excellent effect of decreasing viscosity of a plastisol composition, thus enabling acquisition of a plastisol composition which allows an excellent cured product to be obtained at a low cost.
