  • Patent number: 7544413
    Abstract: Disclosed is a film-forming composition comprising a binder and a pigment mixture present in a pigment to binder ratio of at least 0.8. The pigment mixture consists of at least 80% of titanium dioxide by weight and no more than 20% by weight of non-titanium dioxide pigments, based on the total weight of the pigment mixture, said non-titanium dioxide pigments being selected from the group consisting of carbon black, talc, barium sulfate, magnesium silicate, and combinations comprising two or more of the foregoing. The composition has an adjusted VOC of no more than 100 g/L, is free of all pigments other than those in the pigment mixture, has a viscosity of no more than 200 cps at 384 sec?1, and provides a cured film having an elasticity of at least 20%. The composition provides multilayer coating systems having improved chip performance.

  • Patent number: 7485336
    Abstract: Disclosed is a method for evaluating chip performance of a cured coating system. In one embodiment, the method includes providing a coated substrate comprising a substrate and a cured film of a first coating composition thereon, measuring elastic work energy (We/Wtot) of the cured film, and calculating a % C.P. of the cured film via the formula: % C.P.=7.61636?0.225473 (We/Wtot) wherein a % C.P. of equal to or less than about 3.5% correlates to a total paint loss of equal to or less than 5% of a coating system comprising the first coating composition. The disclosed method predicts the gravelometer chip performance of a cured multilayer coating system comprising a first coating composition and a topcoat by measuring the measuring elastic work energy (We/Wtot) of the cured first coating system alone. In one embodiment, chip performance can be predicted without topcoat application and independent of topcoat composition.
