A water-borne, low-temperature curable polyacrylate (PA) coating was developed by introducing crosslinkages in polymer chains with a polyfunctional comonomer. The effect was investigated of amount of comonomer on the properties of coating latex, such as mechanical properties, solvent resistance, Tg, and surface morphology of polymer. The particle size, size distribution, and the dispersion stability were also measured. Comparisons of the product were carried out with some coatings available from the market.
