ranging from approximately 1000-4500; a polydispersity ranging
from 1.05-2.5; wherein the copolymer is polymerized from a
monomer mixture comprised of one or more non-functional acrylate monomers and one or more functional methacrylate monomers
provided with the crosslinkable groups; wherein the functional
methacrylate monomers are present in an effective amount for producing the copolymer having on an average 2- 25 crosslinkable
groups and having the weight average molecular weight; wherein
the copolymer is produced by free radical polymerization of the
monomer mixture at a polymerization temperature ranging
from120°- 300° C; and wherein the crosslinking component for the
crosslinkable groups is selected from the group consisting of poly-isocyanate, polyamine, ketimine, melamine and a combination
thereof; and wherein the monomer mixture includes 100- 80% of
the total amount of the non-functional acrylate monomers and the
functional methacrylate monomers, percentage is in weight percentage based on the weight of the monomer mixture.
Rohm & Haas high PVC fast-drying aqueous
binder composition
U.S. 2,011,136,936
High PVC fast-drying aqueous binder compositions with small
particle binders and traffic markings made therewith (provides
fast dry binder compositions comprising one or more anionically
stabilized emulsion polymer having a weight average particle size
of from 100 to 165 nm, one or more polyamine, one or more
volatile base and one or more filler, extender and/or pigment in
a composition having a %PVC of from 63 to 80. The invention
provides surprisingly stable fast dry binder compositions for such
a high extender or filler loading and the compositions dry far
faster than binders made with waterborne polymers having a
larger particle size. The invention provides high performance
traffic paints at a reduced cost in use and coated substrates, such
as traffic markings or exterior insulation finishes.
AkzoNobel Coatings patents stain-blocking
aqueous coating composition
WO 2,011,073,164
Stain-blocking aqueous coating composition (said composition
comprising (a) a styrene acrylic resin and, (b) a substituted styrene
acrylate copolymer, wherein, by weight, said styrene acrylic resin is
provided in excess of said substituted styrene acrylate copolymer. A
method is also disclosed whereby this waterborne coating composition is applied to a substrate comprising water extractable staining agents, such as a tannin-containing open grain natural wood).
PPG patents waterborne coating composition
U.S. 2,011,054,113
Waterborne coating compositions, related methods and coated
substrates (disclosed are coating compositions that include a continuous phase that includes water and a dispersed phase that includes a microgel having a mean particle size of greater than 50
nanometres. The microgel is formed from reactants selected so as
to provide a copolymer having a certain calculated Tg and includes a cycloaliphatic (meth)acrylate). CW
