AMINE-IMINO DIALCOHOL NEUTRALIZING AGENTS FOR LOW VOLATILE COMPOUND AQUEOUS ORGANIC COATING COMPOSITIONS AND METHODS FOR USING SAME

Paint, clear coat, stain, adhesive, or other aqueous formulations that contain at least one [(dimethylamino)alkyl]-imino-dialcohol and a alkyd emulsion, polymer latex or polyurethane dispersion binder. Also disclosed are methods for manufacture and use of these formulations. The [(dimethylamino)alkyl]-imino-dialcohols provide aqueous formulations having low odor and reduced volatile organic compounds (VOC). The [(dimethylamino)alkyl]-imino-dialcohols also aid in dispersing pigment and other solids so less co-dispersant is needed for aqueous paint or coating formulations.
