PCT No. PCT/EP94/00015 Sec. 371 Date Aug. 28, 1995 Sec. 102(e) Date Aug. 28, 1995 PCT Filed Jan. 4, 1994 PCT Pub. No. WO94/15974 PCT Pub. Date Jul. 21, 1994The present invention relates to coating compositions including a particular class of oligomeric sterically hindered polyamines as replacements for traditional blocked and unblocked polyamine crosslinkers. The use of these oligomeric sterically hindered polyamine crosslinkers resultss in a desirable pot life/cure speed relationship not generally available with traditional unblocked polyamine crosslinkers, as well as a lower VOC and often better appearance characteristics than generally available with the traditional blocked varieties.
