Coating

U.S. 8,586,697 B2

BASF has obtained a patent for a method
of self-healing cured coatings, which is
comprised of heating a coating of a cured
coating composition for a period of at

contains at least 12 carbon atoms and
(A2) at least one polyol having at least
three hydroxyl groups; (B)at least one
nonblocked or blocked di- or polyisocy-
anate and (C) at least one polyhydroxy
compound selected from the group con-
sisting of polyacrylate polyols, polyester
polyols, polyurethane polyols; polyurea
polyols; polyester polyacrylate polyols;
polyester polyurethane polyols; polyure-
thane polyacrylate polyols, polyurethane-
modified alkyd resins; fatty acid-modified
polyester polyurethane polyols, copoly-
mers with allyl ethers, graft copolymers
from the stated groups of compounds
and mixtures of the stated binders.

Self-Stick Paint Swatch For
Testing Samples on a Wall
U.S. 8,597,752 B1

Myra Hersh has been granted a patent for a removable swatch sheet for temporary attachment to a surface for viewing a paint color painted on the swatch sheet, the swatch sheet is comprised of a multilayer construction comprised of a paint-able paper layer having a top and bottom, the paper preventing paint absorption therethrough and comprised of latex impregnated saturated paper, the paint color being painted on the top covering at least a portion of the swatch sheet, an adhesive surface comprised of a layer of adhesive applied to the bottom of the paper layer, wherein the adhesive is comprised of microsphere adhesive, a release layer attached to the bottom of the paper layer through the adhesive surface, wherein the release layer is comprised of a stay flat liner, the swatch sheet being thin and pliable to be attachable to non-flat and flat surfaces, the swatch sheet attaching flush to a flat surface, the painted swatch sheet being removable and repositionable on the surface.

based on the pigment preparation.

Moisute-Resistant Coating
from Biosphere Industries
U.S. 8,563,140 B2

Biosphere Industries has been granted a patent for a coating comprised of a cellulose ester; a wax comprised of oleamide or N,N’-ethylene-bis-oleamide; a plasticizer; and a solvent.

Bio-Based Coating

U.S. 8,617,304 B2

Ben Wen has been granted a patent for a a bio-based coating comprised of polymerized oil made from oil comprised of triglycerides with unsaturated fatty acid chains, wherein the oil is free of petroleum; and, a catalyst mixed with the oil before it is polymerized, the catalyst is comprised of a thermochromic material comprised of one or more properties that: reduces the temperature for polymerization of the oil to create a suspension that forms a hardened mixture when cooled below approximately 100˚ C and switch-es the hardened mixture from transparent to reflective of infrared light when the temperature rises above a switching temperature in an approximate range of 18˚ - 35 ˚C.
