The present invention provides for a rheology control agent that includes
a following compound represented by the following formula: ##STR00001##
wherein A, B, C and D equal CH.sub.2, CHR, NH, or O, and A, B, C and D
may be the same or different and at least one of A and B equals NH and at
least one of C and D equals NH; and wherein R.sub.1, R.sub.2, and R.sub.3
may be the same or different and represent a linear, branched,
hyper-branched, or dendritic ether, polyether or hydrocarbon based chain,
optionally forming at least one carbon-based ring, being saturated or
unsaturated and R.sub.2 represents linear or branched alkylenes, ethers,
polyethers, or polyester linkages and at least one of R.sub.1, R.sub.2,
and R.sub.3 comprises an ester group or an amide group which is branched
off from the main chain; excluded from Formula (1) is a compound wherein
R.sub.2 is CH.sub.2--CH.sub.2--CH.sub.2--CH.sub.2--CH(C(O)OCH.sub.3), A,
B, C, and D are equal to NH and R.sub.1 and R.sub.3 are both equal to a
linear octyl hydrocarbon chain; the rheology control agent is suitable
for solvent-borne and water-borne coating composition having improved
rheology control useful for OEM refinishing or repainting the exterior of
automobile and truck bodies and parts thereof.
