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&#xb0; C. to less than 80&#xb0; C. to form a crosslinked polyurethane which dries to enable sanding after only 15 to 45 minutes.

Ambient cure, fast dry automotive refinish primer surfacer compositions and methods of use

The present invention provides substantially isocyanate-free multicomponent compositions useful in making rapid dry primer compositions and coatings, the compositions comprising one or more carboxylic acid compounds that contain one of a benzothiazole, benzoxazole, or benzimidazole group, preferably, that contain a benzothiazole group, one or more hydrophobic sulfonic acid catalyst, 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&#xb0; C. to less than 80&#xb0; C. to form a crosslinked polyurethane coating having improved humidity and corrosion resistance.

Ambient cure compositions for making coatings having humidity and corrosion resistance and methods of use

The present invention provides a multicomponent composition that is substantially isocyanate-free and comprises a polycarbamate as a first component having a filler, pigment, extender or matting agent and a second component containing an acidic catalyst an alkanol having one OH group, a polyaldehyde and an acetal or hemiacetal of the polyaldehyde. The compositions are shelf stable and useful as two components and avoid problems caused by combining the catalyst with any filler, pigment, extender or matting agent.

Ambient temperature curable isocyanate-free compositions for preparing crosslinked polyurethanes

The present invention provides personal care formulations containing silicone modified polyolefins and having improved sensory feel, as well as being non-tacky and easily spreadable. The present invention also provides a method for treating body surfaces such as skin, hair, nails, etc., by applying the aforesaid personal care formulations externally to such a surface. The present invention also provides a method for improving the sensory feel of personal care formulations by including one or more silicone modified polyolefins in the formulations.

Silicone modified polyolefins in personal care applications

An organophosphorus compound useful in a phosphorus containing flame retardant and a flame retardant polyurethane foam, where the organophosphorus compound is shown in Formula (I) where Y is selected from the group consisting of an &#x2014;OH group, an &#x2014;NHgroup, an &#x2014;NHRgroup, and an &#x2014;SH group, where Ris a monovalent hydrocarbyl group having 1 to 10 carbon atoms; R is a divalent hydrocarbyl group; X is a heteroatom group; and Rand Rare each independently a substituted or unsubstituted hydrocarbyl group, wherein Rand Rcan be optionally joined to form a ring.
