Low-gloss, two-component clear coats include a base resin including a urethane resin, an isocyanate resin that combines with the base resin immediately prior to application of the low -gloss, two-component clear coat to form a two-component base resin mixture, wherein the two-component base resin mixture comprises from about 20 weight percent to about 40 weight percent urethane resin and from about 20 weight percent to about 40 weight percent isocyanate resin, and a silica-based flattener, wherein the silica-based flattener comprises from about 5 parts by weight per 100 parts by weight of the two-component base resin mixture to about 20 parts by weight per 100 parts by weight of the two-component base resin mixture, wherein the low-gloss, two-component clear coat has a 60&#xb0; gloss finish from 22 gloss units to 34 gloss units when cured.

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, and provides a cured film having an elasticity of at least 20%. The composition provides multilayer coating systems having improved chip performance.

Coatings and coating systems having optimized chip performance and methods of obtaining the same

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 (W/W) of the cured film, and calculating a % C.P. of the cured film via the formula: % C.P.=7.61636&#x2212;0.225473 (W/W) 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 (W/W) of the cured first coating system alone. In one embodiment, chip performance can be predicted without topcoat application and independent of topcoat composition.

The silylated polyurethane polymer includes a polyurethane prepolymer having between greater than about 50 to about 95% of NCO groups terminated with silane capping agents. The polymer has an improved mechanical properties. The polymer can also have between about 5% to less than about 50% of the NCO groups terminated with low molecular weight terminators.

Silylated polyurethanes for adhesives and sealants with improved mechanical properties

The cure-through rate of one-part silylated polymer adhesive/sealant compositions is improved by the addition of a small but effective amount of an alcohol-free hydrophilic solvent. The composition is particularly suitable for packaging in aluminum or aluminum-lined cartridges.
