<p>This invention is directed to (meth)acrylic plastisols having storage stability at 40 DEG C for at least 3 days and plasticizability at a temperature below l20 DEG C in 5 minutes comprising
(l) a poly(meth)acrylate in particle form,
(2) a liquid plasticizer member of the group consisting of:
(a) the reaction product of one mole of a polyether or polyester diol, two moles of a diisocyanate and two moles of a hydroxyalkyl (meth)acrylate;
(b) the reaction product of one mole of a polyester or polyether diol, two moles of a diacyl halide and two moles of a mono-alcohol;
(c) the reaction product of one mole of a polyester or polyether diol, one mole of a diisocyanate, one mole of hydroxyalkyl (meth)acrylate and one mole of an acyl halide; and
(d) mixtures of (a), (b) and (c); and, optionally, either
(3) a free radical thermal initiator, or
(4) a photoinitiator.
<??>The plastisol dispersion after fluxing can form a sealant, coating or adhesive after the curing reaction. </p> |
