Massachusetts Institute of
Technology patents hydrophilic
coating
Patent No. US2010304163
Coatings (a hydrophilic coating can be
applied to virtually any surface to pro-
duce a long lasting, durable antifog effect.
The coating includes a molecular-level
blend of hydrophilic polymers. The coat-
ing can be assembled using a layer-by-
layer assembly process).
PPG patents epoxy coatings
compositions
Patent No. US2010297357

tions (disclosed are high solids, one-com-
ponent, storage stable coating
compositions that include an epoxy resin
comprising more than one 1,2-epoxy
groups per molecule, a hydrocarbon com-
pound having a softening point of from
50 ° C to 140 ° C, an alkoxy-functional
and/or silanol-functional silicone, and a
ketimine curing agent comprising a reac-
tion product of reactants comprising a
polyalkyldiamine component and a ke-
tone component. Also disclosed are sub-
strates at least partially coated with a
coating deposited from such composition
and methods for coating substrates with
such compositions).
Valspar patents high-gloss,
polyvinylidene fluoride-based
coating systems
Patent No. US2010310880
High-gloss, polyvinylidene fluoride-based
coating systems and methods (discloses
solutions of polyvinylidene resins with
very high vinylidene difluoride content in
lactam solvent systems and their uses to
form high gloss coatings, especially high
gloss clear coatings. The invention also
provides coated articles incorporating
these coatings. Advantageously,
polyvinylidene fluoride (PVDF) resins
with sufficiently high vinylidene difluoride
content, as well as a wide variety of ther-
moplastic and thermosetting resins useful
in the practice of the present invention,
can be easily dissolved in and then stay
dissolved in lactam solvents. Conve-
niently, these solutions may be prepared
at room temperature. The ability to coat
such PVDF resins from solution, rather
than from dispersions, is a key factor leading to the high gloss characteristics provided by many embodiments of the
present invention).
Wacker patents compositions
for textile coatings
Patent No. WO2010127977
Compositions for textile coatings (relates to
compositions containing (A)
organopolysiloxanes, which have Si-bound
hydroxy groups, (B) organopolysiloxanes,
which have Si-bound hydrogen atoms, (C)
platinum catalysts, (D) reinforcing fillers,
(E) optionally non-reinforcing fillers, and
(F) optionally inhibitors, which delay a
platinum-catalysed reaction of Si-bound
hydroxy groups and Si-bound hydrogen
atoms at room temperature, with the pro-
viso that the organopolysiloxanes (A) have
viscosities of 500 to 100,000,000 mPa.s at
25 ° C, that the platinum catalysts (C) are
free of phosphoric acid trisamide ligands,
that the reinforcing fillers (D) are present in
amounts of at least 3% by weight, relative
to the total mass of the compositions, that
the non-reinforcing fillers (F) are present in
lower amounts than the reinforcing fillers
(D), that the use of reactive silanes as bond-
ing agents and the use of additional con-
densation catalysts, which accelerate the
condensation reaction of Si-bound hydroxy
groups and/or alkoxy groups, are ex-
cluded).
