Patent number: 6900276Abstract: A low viscosity (and therefore low VOC) resin can be produced by limiting the molar ratio of the reactants, especially the dicarboxylic acid compound, used in the reaction. Specifically, reacting a reaction mixture comprising (i) one mole of a diepoxide having at least two glycidyl ether type epoxy groups; (ii) 0.5 to 2.0 moles of an unsaturated monocarboxylic acid; (iii) 0.1 to 0.5, preferably 0.1 to 0.3, moles of maleic anhydride; and, (iv) water, until substantially all of the epoxy groups disappear leads to the formation of a resin with a high shear (at least 500 s?1) viscosity of less than 1200 cP when measured in a 70% NVM (non-volatile matter) styrene solution. The resin may be used in barrier coatings, gel coatings, skin coatings and as a laminate resin.Type: GrantFiled: February 1, 2002Date of Patent: May 31, 2005Assignee: Cook Composites & Polymers Co.Inventors: L.
