  • Patent number: 10723889
    Abstract: The present invention provides substantially isocyanate-free multicomponent compositions useful in making rapid dry automotive primer compositions and coatings, the compositions having a % PVC of from 20 to 60, or preferably, from 25 to 50, and comprising one or more pigment, extender or filler, one or more a) polycarbamates from alkyd polyol or acrylic polyol and one or more b) a polyaldehydes or the acetal or hemiacetal thereof as a second component. The multicomponent compositions cure quickly at a temperature of from 0° C. to less than 80° C. to form a crosslinked polyurethane which dries to enable sanding after only 15 to 45 minutes.
