The curable polyester resin can be dispersed in water or a solvent and is suitable for waterborne or solventborne coating compositions and powder coating applications. Phenolic based crosslinking coating compositions that contain these curable polyester resins are curable at elevated temperatures.

Abstract: There is now provided a variety of curable polyester resins that cure well with phenolic crosslinking agents. The curable polyester resins include polyester resins that have both carboxyl and hydroxyl functionalities and a high ratio of carboxyl functionalities to hydroxyl functionalities; unsaturated curable polyester having residues of an ?,?-unsaturated polycarboxylic acid compound with at least one unsaturation in a position that is ?,? relative to a carbonyl group and not located on an aromatic ring; and a curable polyester resin containing beta-ketoacetate moieties without vinyl unsaturation. The curable polyester resin can be dispersed in water or dissolved in a solvent and is suitable for waterborne or solventborne coating compositions. Phenolic based crosslinking coating compositions that contain these curable polyester resins cure well with phenolic resin crosslinking compounds with a wide variety of reactive curable polyester resins or other kinds of polyester resins.

Abstract: This invention relates to a resole phenolic resin comprising the residues of (a) from about 50 to 100 mole % of a meta-substituted phenol [phenolic component (a)], (b) from 0 to about 50 mole % of at least one phenolic component [phenolic component (b)] other than said meta-substituted phenol, and (c) from about 150 to about 300 mole % of at least one aldehyde, wherein the mole percentages of said phenolic components (a) and (b) are based on the total moles of phenolic components (a) and (b); wherein the mole percentages of said aldehyde component is based on the total moles of said phenolic components (a) and (b), and wherein said resole phenolic resin is soluble in an organic solvent and curable with a functional polyester.

Abstract: A thermosetting composition having: I) an unsaturated curable polyester comprising the residues of an ?,?-unsaturated polycarboxylic acid compound, said ?,?-unsaturated polycarboxylic acid compound having at least two carboxylic acid groups or at least one anhydride group, and having at least one unsaturation in a position that is ?,? relative to a carbonyl group and not located on an aromatic ring; and II) a phenolic resin having at least one methylol group. The unsaturated curable polyester resin can be dispersed in water or dissolved in a solvent and is suitable for waterborne or solventborne coating compositions. Phenolic based crosslinking coating compositions that contain these unsaturated curable polyester resins are curable at elevated temperatures.

Abstract: Waterborne coating compositions are disclosed that include a latex emulsion polymer, and, as a coalescent, a diester of hydroxypivalyl hydroxypivalate. The coating compositions of the invention have a reduced VOC content and provide satisfactory coalescing activity.

Abstract: A computing device accessory is provided. The computing device accessory includes a first cover segment that has an inner surface and an exterior surface. The interior surface includes a recessed region to receive a base of a tablet computing device. The computing device accessory also includes a magnetic component provided with the first cover segment, where the magnetic component is positioned to actively retain the tablet computing device when the base of the tablet computing device is received in the recessed region.

Abstract: A sulfopolyester containing residues of 2,2,4,4-tetralkylcyclobutane-1,3-diol such as 2,2,4,4-tetramethylcyclobutane-1,3-diol is highly dispersible in water. This allows one to reduce the content of sulfonate groups or reduce the amount of ethylene glycol or other hydrophilic glycols to retain good water resistance in cured coatings. The sulfopolyester may also be a reaction product of a 2,2,4,4-tetralkylcyclobutane-1,3-diol along with 1,4-cyclohexanedimethanol, neopentyl glycol, or a mixture thereof with an acid component. Coating compositions may also contain these sulfopolyesters along with water and a polymer resin.

Abstract: A combination chain and strap tie-down apparatus and system. An elongated shaft is attached to an automobile transport platform. A ratchet gear wheel having engagement teeth and a ratchet wrench socket wheel having a plurality of wrench apertures can be located on one side of the shaft together or on opposite sides of the shaft. A strap spool is slidably connected to the shaft. The spool generally includes two side plates connected by a strap attachment bracket. A quick release pawl is connected to the platform adjacent the ratchet gear wheel for engagement with the engagement teeth. The pawl is connected to an elongated rod that is connected to the platform generally parallel with the shaft. The rod partially protrudes adjacent the ratchet wrench wheel. A spring is connected to the shaft adjacent the pawl. A shaft extension is included on one end of the shaft for receiving a chain.
