  • Patent number: 10836856
    Abstract: 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.

  • Patent number: 10259987
    Abstract: An amine adduct is made by (1) forming an addition intermediate by heating a mixture comprising at least one diene and at least one unsaturated fatty acyl compound, and reacting the addition intermediate with a diamine to form the amine adduct, or by (2) reacting at least one unsaturated fatty acyl compound with at least one diamine to form an amine intermediate, and heating a mixture of the amidoamine intermediate and at least one diene to form the amine adduct, or by (3) reacting at least one unsaturated fatty tertiary amine compound with at least at least one diene to form the amine adduct.
