An adhesive composition that includes: one or more polyester polyether copolymers of formula I: wherein Nu is a predominately cyclic nucleus and Ris randomly selected from either a Calkylene or an amorphous, long-chain polyether subunit including a polyoxyalkylene group; one or more polyisocyanate prepolymers that includes the reaction product of: one or more polyols; and a polyfunctional isocyanate having a functionality of more than about 2; polymeric MDI; and a first aromatic or aromatic-aliphatic polymer tackifying resin having a softening point of equal to or greater than about 100&#xb0; C.

Hot melt moisture cure adhesive composition

A hot melt pressure sensitive adhesive composition includes ABA block copolymer(s), a midblock resin, a plasticizer, and optionally, an endblock resin. The A block is derived from styrene and B block is derived from butadiene or its hydrogenated version. The block copolymer(s) has an average styrene content of from about 15% to about 35%, an average diblock content of no less than about 20%, and an average solution viscosity of less than about 1,000 cps.

High shear pressure sensitive adhesive composition

The invention is directed to a low gloss powder coating composition comprising a first component (a) and a second component (b). The first component (a) comprises a mixture of (i) at least one glycidyl group-containing acrylic resin having epoxide equivalent weight of from about 250 to about 1500 and glass transition temperature of from about 30&#xb0; C. to about 80&#xb0; C.; and (ii) a curing agent. The second component (b) comprises at least one carboxyl-group containing material having acid number of from about 10 to about 300 and is not substantially compatible with the first component (a). The two components are dry-blended to obtain the powder coating composition.

Low gloss powder coating compositions

Powder coating of cooh acrylic resin, polyepoxide and low t catalyst

A thermosetting weatherable powder coating composition applyable to a temperature sensitive substrate by means of electrostatic spray or fluidized bed, and curable at low temperature to form a textured surface to hide irregularities on the surface of the underlying substrate. The powder coating composition includes a hardener with a functionality of 2 or greater capable of reacting with an acid or anhydride functional group, a polymeric coreactant with a functionality of 2 or greater capable of reacting with the hardener, a carboxylic acid functional polyester and optionally, a catalyst, but no texturing agent. The polymeric coreactant is made by polymerizing an ethylenically unsaturated monomer and at least one carboxyl acid functional ethylenically unsaturated monomer or anhydride functional ethylenically unsaturated monomer, and mixtures thereof.
