A coating composition comprising a film forming binder of a. at least
one polymer that has pendant groups, such as, hydroxyl, carboxyl,
glycidyl, amine, amide, silane and mixtures thereof that are reactive
with a crosslinking component and the polymer has a glass transition
temperature (Tg) of 10 to 80.degree. C.; b. a polytrimethylene ether diol
having a Mn (number average molecular weight) of 500 to 5,000; and c. a
crosslinking component, such as, organic polyisocyanates, melamine
formaldehydes, alkylated melamine formaldehydes, benzoquanamine
formaldehyde, urea formaldehyde, polyepoxides, silane resin and any
mixtures thereof; wherein the coating composition can be used as a clear
coating composition and can contain pigments and may be used as a
pigmented top coating, a pigmented base coating, a primer or primer
surfacer coating and is useful for coating automobile and truck bodies
and parts, industrial equipment, appliances and exterior structures.
