Abstract: An embodiment of the invention provides an anionic/non-ionic water based polymer comprising polyurethane and polyurea. The polymer is approximately 30 to 40 weight percent non-volatile and has a viscosity of between approximately 1400 and 1500 cps. Also provided is a method for producing an anion/non-ionic water based polyurethane/polyurea polymer, the method comprising heating dimethylolpropionic acid; combining the dimethylolproprionic acid with heated PEG to create a slurry; adding isophorone diisocyanate (IPDI) to the slurry to create a mixture; and heating the mixture in the presence of a catalyst. The prepolymer is then salted out after catalyst is added and reaction complete. This salted prepolymer is then added to ethylene diamine in water to chain extend and promote water solubility. Also provided is a film comprising the polymer.

Abstract: A water-reducible polyester resin for use in producing urethane coatings comprises the reaction product of: a) hexahydrophthalic anhydride, trimellitic anhydride or phthalic anhydride; b) 1,4-cyclohexane dimethanol or trimethylol propane or mixtures thereof; and c) a polyethylene glycol selected from the group consisting of polyethylene glycols, methoxy polyethylene glycols and trifunctional polyethylene glycols having a molecular weight no greater than approximately 1050; the reaction product having a functionality between approximately 2 and 2.6. Another water-reducible polyester resin comprises the same components and a specified nonionic surfactant. Urethane coatings containing such polyester resins and a diisocyanate are also disclosed.

Abstract: A water-reducible binder for coatings comprises the reaction products of a) a phenolic resin comprising the reaction product of bisphenol A, t-butyl phenol and formaldehyde; b) an alkylene carbonate alkoxylating agent; c) a diol selected form the group consisting of 1,4-cyclohexanedimethanol, 3,5,5-trimethylpentane diol and neopentyl glycol; and d) trimellitic anhydride. Methods for preparing such a water-reducible binder and coating systems comprising such a binder are also disclosed.
