Valspar Patents Treatment
for Cement Composite
U.S. 8,202,581 B2
Valspar Sourcing, Inc. has been granted
a patent for a method for preparing a
coated article comprised of providing a cement fiberboard substrate having an outer
surface, applying directly to the cement fiberboard substrate an aqueous treatment

Imperial Chemical Patents
Low VOC Coatings
U.S. 8,188,183 B2
Imperial Chemical Industries has been
granted a patent for an autoxidisable
coating comprised of a liquid dispersion
medium and a binder wherein the binder
is comprised of an unsaturated copolymer which is produced by reacting at least
one unsaturated fatty acid drying oil component and an ethylenically unsaturated
monomer, the unsaturated fatty acid reacts
with an oxirane group on the ethylenically unsaturated monomer to yield a first
reaction product and subsequently reacting the first reaction product with one or
more monomers copolymerizable with the
product of the first reaction and selected
from the group consisting of acrylic acid
esters, methacrylic acid esters, acrylic acid,
methacrylic acid, acrylic acid esters of aliphatic alcohols, acrylic acid esters or aromatic alcohols, methacrylic acid esters of
aliphatic alcohols, methacrylic acid esters
of aromatic alcohols, styrene, substituted
styrenes, vinyl carboxylate esters and vinyl
carboxylate olefins selected from ethylene,
propylene or butene-1 and styrene or its
homologues and at least 15% by weight
of the binder is present as microgel, which
is the result of the two reaction steps and
which is insoluble in tetrahydrofuran.
United Technologies
Patents Thermal Barrier
Coating
U.S. 8,216,687 B2
United Technologies Corporation has
been granted a patent for an article comprised of a metallic substrate; a coating
system atop the substrate and comprised
of an alumina-chromia layer having a
thickness at least 50% of a total thickness
of the system; and a bondcoat between
the substrate and the alumina-chromia
layer.
Omnitech Environmental
Patents Coating Additive
U.S. 8,188,184 B2
Omnitech Environmental has been
awarded a patent for a vehicle system
comprised of by weight relative to the
vehicle system, 4%-45% of a first component, the first component comprised
of at least one material selected from
the group consisting of an acrylic resin
solution, a latex dispersion, a urethane
solution, a microcrystalline wax solution, and a vegetable oil; 50%-90% of
a second component, the second component comprised of at least one material
selected from the group consisting of a
fumaric resin solution and an acrylic resin emulsion; and 0.5%-10% of an aqueous solution of an additive comprised of
the reaction product of a first reagent
comprised of a carboxylic acid; and
a second reagent comprised of at least
one material selected from the group
consisting of a dialkylaminoalkyl acrylate monomer and a dialkylaminoalkyl
methacrylate monomer.
Polyguard Products Patents
Mold Inhibiting Coating
U.S. 8,202,919 B2
Polyguard Products, Inc. has been granted a patent for a composition for application to provide a water barrier coating
on a construction surface comprised of
at least one of wood, cement, masonry,
plaster, stone, clay and brick. The composition is comprised of an aromatic
hydrocarbon solvent; styrene-based
polymer; and an antimicrobial effective
amount of triclosan.
Sun Chemical Patents Multi-
Color Pearlescent Pigments
U.S. 8,211,224 B2
Sun Chemical Corp. has been granted a
process for making a pearlescent pigment
comprised of reducing a metal oxide
coated substrate with a hydrogen source
in the presence of a particulate noble metal catalyst in a liquid medium.
Rockwood Patents Process
to Produce Red Iron Oxide
U.S. 8,206,681 B2
Rockwood Italia SpA has been granted
a patent for a process for producing red
iron oxide comprised of providing a ferrous chloride feedstock, precipitating
high surface area lepidocrocite seeds having a BET surface area of greater than
175 m2/g by mixing the ferrous chloride
feedstock with an alkali and oxidizing the
obtained mixture and growing the lepidocrocite seeds at an overall acidic pH,
wherein the growing of the lepidocrocite
seeds is carried out by adding further ferrous chloride feedstock and alkali to the
mixture, whereby the lepidocrocite converts into hematite. CW
