PURPOSE: To prepare the titled composition having excellent weather resistance and chemical resistance, and high durability owing to the moderate strength and flexibility, by compounding an acrylic acid ester, a specific polymer, a plasticizer, a compound containing polymerizable double bond, a paraffin, etc. at specific ratios.
CONSTITUTION: The objective composition is prepared by compounding (A) 100pts.wt. of a mixture of (i) 51W85wt% of a (meth)acrylic acid ester, (ii) 10W 24wt% of a polymer or copolymer soluble in the component (i), and (iii) 5W25% of a plasticizer soluble in the component (i) (e.g. dibutyl phthalate) with (B) 0.1W10pts.wt. of a compound having two or more polymerizable double bonds in one molecule [e.g. ethylene glycol di(meth)acrylate] and (C) 0.1W5pts.wt. of a paraffin and/or a wax having a melting point of ≥40°C.
EFFECT: It has moderate curing time and no deteriorating effect to the workability in the application. It has excellent curability and workability even at a temperature of as low as ≤5°C.
USE: Floor coating, wall coating and road marking.
