  • Low VOC, high solid deck membranes
    Patent number: 11866607
    Abstract: A basecoat coating composition includes an aromatic polyurethane pre-polymer having isocyanate terminal end groups, a first solvent and optionally a second VOC-exempt solvent, in which the total composition formulation has a VOC content of less than 97 g/L. A topcoat coating composition includes an aliphatic polyurethane pre-polymer having isocyanate terminal end groups, a first solvent and optionally a second VOC-exempt solvent, in which the total composition formulation has a VOC content of less than or equal to 95 g/L. The total composition formulations of the basecoat and/or topcoat may have a VOC content of less than 50 g/L. A membrane system may include an optional primer coating, and the above described basecoat and topcoat coating compositions.
