U.S. 8,257,796 B2
The Sherwin-Williams Company has
been awarded a patent for a process for
providing a polymer coating to a substrate. The process is comprised of applying the coating to the substrate and
broadcasting solid decorative or protective materials onto the liquid surface of
the coating before it completely cures or
dries, and then subsequently allowing the
coating to cure or dry, the improvement
which is comprised of utilizing as the
coating a multi-component curable composition that is reactive upon admixing of
the components and wherein the composition is comprised of: A: a first component which is comprised of a first amine
functional adduct which is comprised of
the reaction product of a stoichiometric
excess of a diamine and a compound having an epoxide group and an alpha, beta
unsaturated carbonyl group; B: a second
component which is comprised of at least
one compound having an average of
more than 2.0 groups per molecule which
are reactive with amines.

Conductive Powder and
Adhesive
U.S. 8,262,940 B2
Nippon Chemical Industrial Co. has obtained a patent for a coated conductive
powder obtained by coating the surfaces
of conductive particles with insulating
inorganic fine particles, wherein the volume resistivity value of the coated conductive powder is 1 Ω·cm or less, the
specific gravity of the insulating inorganic fine particles is 5.0 g/ml or less, the
particle diameter ratio of the insulating
inorganic fine particles to the conductive
particles is 1/100 or less, and the insulating inorganic fine particles adhere to
the surfaces of the conductive particles,
wherein the coated conductive powder
satisfies n= 4× 104 to 3×1010, in the following formula: the amount of the insulating inorganic fine particles added (g)
with respect to 1 g of the conductive particles n×(r23×d2)/(r13×d1) where n is a
constant; r1 is a radius of the conductive
particles; d1 is a specific gravity of the
conductive particles; r2 is a radius of the
insulating inorganic fine particles; and
d2 is a specific gravity of the insulating
inorganic fine particles.
PPG Patents Antimicrobial
Coating
U.S. 8,258,202 B2
PPG Industries Ohio, Inc. has been granted a patent for a coating composition
comprised of (a) a film-forming resin;
(b) a porous solid comprised of an ion-exchange ceramic comprised of pores
having antimicrobial metal ions disposed
therein; and (c) a halogen ion-containing
onium compound having a minimum molecular diameter according to the equation: D=2*((0.75*V)π)1/3 where D is
the minimum molecular diameter and V
is the van der Waals volume of the molecule, and the minimum molecular diameter is greater than the size of the pores
having antimicrobial metal ions disposed
therein, wherein (b) and (c) are present
in amounts such that the composition,
when applied onto a substrate and cured,
provides a cured coating that exhibits
UV color stability comparable to the
UV color stability exhibited by the same
composition that does not include (b) and
(c), and wherein the halogen counterion-containing onium compound is a monomeric quaternary ammonium salt having
the formula: R4N+X−, where each R is a
hydrocarbon and each may be the same
or different and X is a halogen atom.

amount of each filler present or wherein
the two or more different types of fillers
each have a different crushed DBP and
the blend has a crushed DBP that is lower
than any crushed DBP of each individual
filler present.
