BASF patents coating composition
Patent No. U.S. 7,989,070 B2
BASF Coatings GmbH has received a
patent for a coating composition comprised of a crosslinkable carbamate-func-tional resin; and an aminoplast comprised
of the reaction product of an aldehyde
and a melamine; wherein the aminoplast
has a content of imino groups of less than
or equal to approximately 10%, a content
of alkylol groups of at least 15%, and a
remainder of groups being alkoxyalkyl
groups, all based on a total number of reactive sites present in the melamine prior
to reaction.
NDSU patents thermoset
siloxane-urethane fouling
release coating
Patent No. U.S. 7,989,074 B2
North Dakota State University Research
Foundation has obtained a patent for a sub-
strate having a surface capable of being ex-
posed to aquatic conditions; wherein the
surface has a fouling release coating thereon;
and the coating is comprised of a polymeric
material prepared by reacting a mixture
comprised of an amino functional poly-
organosiloxane comprised of aminoalkyl
terminated polydimethylsiloxane; polyiso-
cyanate; and polyol, which is comprised of
hydroxy-functional poly(meth)acrylate;
wherein the polyisocyanate is comprised of
hexamethylene diisocyanate trimer,
isophorone diisocyanate trimer or a mixture
thereof; and the hydroxy-functional
poly(meth)acrylate is formed from a
monomer mixture comprised of hydrox-
yalkyl acrylate and alkyl acrylate; and the
fouling release coating has an initial water
contact angle of at least about 90°.
Bayer MaterialScience patents
ethylenically unsaturated
polyisocyanate addition
compounds
Patent No. U.S. 7,759,447 B2
Bayer MaterialScience LLC has been
granted a patent for polyisocyanate addi-
tion compounds, which are substantially
free from isocyanate groups and are prepared from one or more polyisocyanate
adducts containing uretdione, allophanate,
carbodiimide and/or oxadiazinetrione
groups and/or NCO prepolymers, contain
urethane groups, contain fluorine (
calculated as F, AW 19) in an amount of 0.01%
to 50% by weight, and contain ethylenically unsaturated groups (calculated as
C;C, MW 24) in an amount of 2% to
40% by weight, wherein at least a portion
of the ethylenically unsaturated groups are
incorporated by reacting an isocyanate
group with the reaction product of
(meth)acrylic acid with ;-caprolactone and
wherein the preceding percentages are
based on the solids content of the polyisocyanate addition compounds and wherein
fluorine is incorporated by reacting an isocyanate group with a compound containing two or more carbon atoms, one or
more hydroxyl groups and one or more
fluorine atoms to form urethane groups
and optionally allophanate groups, provided that more than 50 mole percent of
the groups that chemically incorporate fluorine into the polyisocyanate addition
compounds are urethane groups.
Bunge Fertulizantes patens
aluminum phospate pigments
Patent No. U.S. 7,763,359 B2
Bunge Fertilizantes S.A., São Paulo Brazil
and Universidade Estadual de Campinas,
Campinas, Brazil have received a patent
for a method of making a coating compo-
sition comprised of a binding polymer and
an opacifying pigment, the method is com-
prised of the following steps: forming an
opacifying pigment by combining phos-
phoric acid, aluminum sulfate and sodium
hydroxide simultaneously, and allowing
the combined materials to react with one
another for approximately 30 minutes to
form a precipitate; drying the precipitate
at a temperature of below approximately
130° C to form amorphous aluminum or-
thophosphate particles comprised of one
or more closed voids per particle, wherein
the particles are substantially free of open
pores; and combining a volume of the
amorphous aluminum orthophosphate
with a binding polymer to form the opacifying coating composition.
PPG patents method for
selectively coating substrates
Patent No. U.S. 7,824,735 B2
PPG Industries has been granted a patent
for a method for selectively coating a sub-
strate comprised of applying an acid to a
portion of the substrate, wherein the acid
is comprised of R—C(O)—OH, where R
represents a C1-C10 group, formic acid,
carbonic acid, sulfonic acids, and/or phos-
phoric acids; coating the substrate with a
coating comprised of a component that
reacts with the acid; and removing the
coating from the portion of the substrate
to which the acid has been applied.
Boeing patents spectrally
selective coatings
Patent No. U.S. 2010304044
Spectrally selective coatings and associated
methods for minimising the effects of light-
ing strikes (discloses a method for reducing
structural damage to a substrate resulting
from interaction between the substrate and
a plasma, the method including the steps of
identifying a wavelength at which a spec-
tral radiance of the plasma is at a peak, the
wavelength being a function of a tempera-
ture of the plasma, preparing a coating ca-
pable of imparting to the substrate a
threshold electromagnetic reflectivity over
a spectral band about the wavelength, and
applying the coating to the substrate. In em-
bodiments the coating includes a binder
and a plurality of pigment particles, said
pigment particles of said plurality including
a quarter wave stack including silicon diox-
ide and titanium dioxide).
