U.S. 8,623,460 B2
Valspar has been granted a patent for a
method for making an article comprised
of providing a substrate comprised of at
least one of ceramic, glass and polymeric materials; contacting a surface of tbe
substrate with a solution comprised of
at least one of a Ga, W, Al, Mn, Mo, Sb
or Te metal ion or mixtures thereof at a
concentration of approximately 0.01 to 3
mmol/l and pH of approximately 4.0 to
6.0 to form an activated surface on the
substrate; and applying a metal coating
on the activated surface of the substrate,
wherein the solution does not contain
Pd(II) ions, and wherein the article is
copper-free.
Method For Restoring
Antimicrobial Hydrophilic
Coatings
U.S. 8,623,453 B2
Hamilton Sundstrand Space Systems
International has obtained a patent for a
method for restoring a silver oxide-con-taining hydrophilic coating. The method is
comprised of heating the coating to a first
temperature between approximately 260°
C and about 540° C in a chamber during a
heating step; adding ozone to the chamber;
maintaining the coating at a second temperature between 260° C and 540° C in an
environment containing oxygen and ozone
for less than 24 hours during a contaminant
removal step; and reducing the temperature
of the coating to a third temperature lower
than the second temperature and maintaining the coating at the third temperature for
between about 15 minutes and about 4
hours during a silver oxide restoration step.
Metal Components
With Silicon-Containing
Protective Coatings Free Of
Chromium
U.S. 8,623,461 B2
MT Coatings LLC has obtained a patent
for a coating process for protecting a sur-
face of a substantially chromium-free metal
component, the coating process is comprised
of combining a substantially chromium-free
silicon-containing fluid composition com-
prised of a silane liquid with a dopant that is
dissolvable in the silane liquid and is selected
from the group consisting of yttrium, haf-
nium, and combinations thereof; applying a
layer of the substantially chromium-free, sil-
icon-containing fluid composition to at least
a portion of the surface; curing the substan-
tially chromium-fee, silicon-containing fluid
composition after the layer is applied to the
surface; placing the cured substantially chro-
mium-free, silicon-containing fluid composi-
tion in layer in a non-oxidizing atmosphere
before heating; and heating the cured sub-
stantially chromium-free, silicon-containing
fluid composition in layer to a temperature
of approximately 70 percent of the melting
temperature of the substantially chromium-
free component or to the eutectic tempera-
ture of silicon and the metal constituting the
substantially chromium-free metal compo-
nent to form a substantially chromium-free,
silicon-containing protective coating on the
surface that includes silicon from the cured
silicon-containing fluid composition and
metal from the metal component.
AkzoNobel Patents
Redispersible Polymer
Powder
U.S. 8,623,462 B2
AkzoNobel has been granted a patent for a
water-redispersible polymer powder composition containing at least one modified natural latex obtained by mixing and reacting
natural latex with at least one radical initiator and/or with at least one oxidizing agent,
wherein the natural latex and the at least one
radical initiator and/or at least one oxidizing agent are mixed in an aqueous phase
and subsequently drying of the obtained
mixture, wherein the drying is selected from
spray drying, pulse combustion spray drying, freeze drying, fluidized bed drying, drum
drying and flash drying, said water-redispersible polymer powder composition further containing at least one water insoluble,
synthetic polymer prepared by means of
emulsion, suspension, microemulsion and/or
inverse emulsion polymerization.
H.B. Fuller Patents Hot
Melt Adhesive
U.S. 8,623,480 B2
H.B. Fuller has been granted a patent for a
hot melt adhesive composition comprised of
at least 55 percent by weight of a first polymer
consisting of a non functionalized amorphous
poly alpha olefin polymer comprising greater
than approximately 50 percent by weight
polypropylene; a second polymer selected
from the group consisting of polypropylene
homopolymers, propylene copolymers, and
combinations thereof; functionalized polypropylene wax; and polyethylene wax; the
adhesive composition has a viscosity of no
greater than 2000 centipoise at 176.7° C.
Polysaccharide-Based
Pigments And Fillers
U.S. 8,623,504 B2
Teknologian Tutkimuskeskus VTT has
been granted a patent for particles of a
polysaccharide derivative, having at least
one substituent with conjugated unsaturated bonds and exhibiting an index of
refraction in excess of 1.50, comprised of
a polysaccharide derivative selected from
the group of esters or ethers of starch, cellulose, dextrin or a hemicellulose, wherein
the substituent is selected from aromatic
radicals having 6 to 18 carbon atoms, alicyclic groups having 6 to 12 carbon atoms
and at least two conjugated unsaturated
bonds, and linear or branched aliphatic
hydrocarbyls having at least two conjugated unsaturated bonds, and mixtures of
two or more, and wherein the polysaccharide is comprised, in addition to a first substituent comprised of the substituent with
conjugated unsaturated bonds, a second
substituent bonded by ester or ether bonds
to the polysaccharide, wherein the second
substituent is comprised of a hydrocar-byl radical derived from a C2-20 aliphatic
group. CW
