  • Patent number: 6827983
    Abstract: The present invention relates to a storage-stable, waterborne, one-component, coating composition, which can be cured at temperatures below 100° C. to provide a stone chip resistant and sandable coating, containing as the binder a polyurethane dispersion A, which after physical drying results in a coating having a pendulum hardness according to DIN 53 157 of >90 s; a polyurethane dispersion B, which after physical drying results in a coating having a pendulum hardness (DIN 53 157) of <90 s; and a melamine resin C, which is preferably highly reactive. The present invention also relates to a process for coating substrates with these coating compositions and to the resulting substrates.

  • Patent number: 6753386
    Abstract: The present invention relates to a film forming composition, a method of forming the composition, and application of the composition to coating formulations which provide a cured coating having acid rain resistance. A film-forming polyurethane polyol composition comprises a reaction product of an n-functional isocyanate (wherein n is a number ranging from about 2 to about 5) with at least one diol or triol or mixtures thereof and a compound containing isocyanate-reactive functional groups, preferably a monofunctional alcohol or thiol. The low viscosity polyurethane polyol of the present invention is typically crosslinked/cured using a melamine to produce a cured coating which is highly acid etch resistant as well as having other desirable physical-mechanical properties. The coating compositions have improved flow characteristics compared to compositions containing polyurethane polyols prepared without the monofunctional alcohols or thiols.
