(Meth)acrylic plastisols having storage stability at 40°C for at least 3 days and plasticizability at a temperature below 120°C in 5 minutes comprisingn (1) a poly(meth)acrylate in particle form, (2) a liquid plasticizer member of the group consisting of (b) the reaction product of one mole of a polyester or polyether diol, two moles of a diacyl halide and two moles of a monoalcohol; and (d) mixtures of (b) with (a) and/or (c) where (a) is the reaction product of one mole of a polyether or polyester diol, two moles of a diisocyanate and two moles of a hydroxylalkyl (meth)acrylate; and where (c) is the reaction product of one mole of a polyester or polyether diol, one mole of a diisocyanate, one mole of a hydroxyalkyl (meth)acrylate and one mole of an acyl halide; and, optionally, eithern (3) a free radical thermal initiator, or (4) a photoinitiator. n The plastisol dispersion after fluxing can form a sealant, coating or adhesive after the curing reaction. |
