Alkoxysilane terminated resin and methods of making and using same

A water-curable resin composition containing less than about 1 wt-% of a solvent and having a viscosity of no greater than about 500 Pa-s under ambient conditions, said resin composition comprising:

• (a) a water-reactive alkoxysilane terminated nitrogen-containing prepolymer of the formula:
• ##STR6## wherein:
• (i) Q is a polyol residue;
• (ii) W is --NH--C(O)--X(R.sup.2.sub.2-n-q)- or --X--C(O)--NH--;
• (iii) X is --N--, --O--, or --S--;
• (iv) Y is --N--, --O--, --S--, carbamylthio (--S--C(O)--NH--), carbamate (--O--C(O)--NH--), or unsubstituted or N-substituted ureido (--N(C(O)--NH--)-);
• (v) R.sup.1 is a substituted or unsubstituted divalent bridging C.sub.1 -C.sub.200 hydrocarbon group, optionally interrupted in the backbone by 1-50 nonperoxide --O--, --C(O)--, --S--, --SO.sub.2 --, --NR.sup.6 --, amide (--C(O)--NH--), ureido (--NH--C(O)--NH--), carbamate (--O--C(O)--NH--), carbamylthio (--S--C(O)--NH--), unsubstituted or N-substituted allophonate (--NH--C(O)--N(C(O)--O--)-), unsubstituted or N-substituted biuret (--NH--C(O)--N(C(O)--NH--)-), and N-substituted isocyanurate groups;
• (vi) R.sup.2 can be present or absent, and is selected from the group consisting of a H and a substituted or unsubstituted C.sub.1 -C.sub.20 hydrocarbon group, optionally interrupted in the backbone by 1-10 nonperoxide --O--, --C(O)--, --S--, --SO.sub.2 --, or --NR.sup.6 -groups;
• (vii) R.sup.3 is a substituted or unsubstituted divalent bridging C.sub.1 -C.sub.20 hydrocarbon group, optionally interrupted in the backbone by 1-5 nonperoxide --O--, --C(O)--, --S--, --SO.sub.2 --, or --NR.sup.6 -groups;
• (viii) R.sup.4 is a C.sub.1 -C.sub.6 hydrocarbon group or --N.dbd.C(R.sup.7).sub.2 ;
• (ix) each R.sup.5 and R.sup.7 is independently a C.sub.1 -C.sub.6 hydrocarbon group;
• (x) R.sup.6 is a H or a C.sub.1 -C.sub.6 hydrocarbon group;
• (xi) n=1-2 and q=0-1, with the proviso that when X is N, n+q=1, and when X is S or O, n+q=2;
• (xii) m=2-3;
• (xiii) z=1-3;
• and
• (xiv) u=the functionality of the polyol residue =0-6, with the proviso that when u=0, the water-reactive alkoxysilane terminated prepolymer is of the formula ##STR7## wherein R.sup.1, W, R.sup.3, R.sup.4, R.sup.5, m, n, and z are as defined above.
