1. A method of coating a fiber/polymer composite with a primer surfacer, comprising applying to the composite a composition curable below 40° C. and comprising
a. 1%-50% by mass of at least one hydroxy-functional binder selected from the group consisting of poly(meth)acrylates, polyesters, and polyurethanes, b.
i. 0.01%-5% by mass of at least one electrically conductive pigment selected from the group consisting of conductive carbon blacks, graphene, fullerenes, doped pearlescent pigments and conductive barium sulfate,orii. 0.001%-5% by mass of at least one electrically conductive pigment selected from carbon nanotubes and conductive polymers, c. 5%-80% by mass of at least one electrically nonconductive pigment selected from the group consisting of titanium dioxide, lime, silicon dioxide, talc and silicas, d. 0.001%-25% by mass of at least one compound selected from the group consisting of polyethers, oligoethers, polysiloxanes, and aliphatic ethynols, as flow control agent, e. 0.05%-20% by mass of at least one nonblocked polyisocyanate, f. 10%-60% by mass of water, and g. 0%-20% by mass of organic solvents,so as to produce a coating, and wherein the percent by mass figures are based on the total mass of the composition. |
