Abstract:
A coating composition comprising:(a) a bicyclic oxazolidine compound of the structure: ##STR7##whereinz is from 0 to 9;m and p are independently selected from 1 and 2;R.sub.3, R.sub.4, R.sub.5 and R.sub.6 may be the same or different and are selected from the group of hydrogen, linear or branched (cyclo)alkyl, and linear or branched aryl, optionally substituted;R.sub.3 and R.sub.4, and R.sub.5 and R.sub.6 may be joined together to form a 5 or 6 carbon ring with the attached carbon atom of the ring in the formula, i.e. R.sub.3 and R.sub.4, and R.sub.5 and R.sub.6 collectively represent a tetramethylene or a pentamethylene group; andR.sub.7 is a mono- or multivalent aliphatic, aromatic, arylaliphatic or cycloaliphatic moiety which may optionally contain oxygen, nitrogen, sulphur, and silica; and R.sub.7 may be H when z=0;(b) a monocyclic oxazolidine compound of the structure: ##STR8##whereinz is from 0 to 9;n is 2 or 3;R.sub.1 and R.sub.2 may be the same or different and are selected from the group of hydrogen, linear or branched (cyclo)alkyl, and linear or branched aryl, optionally substituted;R.sub.1 and R.sub.2 may be joined together to form a 5 or 6 carbon ring with the attached carbon atom of the ring in the formula, i.e. R.sub.1 and R.sub.2 collectively represent a tetramethylene or a pentamethylene group; andR.sub.7 is a mono- or multivalent aliphatic, aromatic, arylaliphatic or cycloaliphatic moiety which may optionally contain oxygen, nitrogen, sulphur, and silica; and R.sub.7 may be H when z=0; and(c) an isocyanate functional compound.
