There is provided a two-pack composition for making urethane-containing structures, said composition comprising (a) a first pack comprising at least one reaction product of at least one polyisocyanate and at least one polyol, wherein said first pack has %NCO of 6% or greater, and (b) a second pack comprising at least one polyol and at least one amine catalyst, wherein the reactive mixture formed by admixing said first pack and said second pack is capable of curing in the absence of water; and wherein said reactive mixture comprises less than 3% solvent by weight based on the weight of said reactive mixture. Also provided are methods of making such urethane-containing structures, and the urethane structures made thereby.

I claim: 1. A two-pack composition for making urethane-containing structures, said composition comprising (a) a first pack comprising at least one reaction product of at least one polyisocyanate selected from the group consisting of aliphatic polyisocyanates, 4,4′-diphenylmethane diisocyanat
I claim: 1. A two-pack composition for making urethane-containing structures, said composition comprising (a) a first pack comprising at least one reaction product of at least one polyisocyanate selected from the group consisting of aliphatic polyisocyanates, 4,4′-diphenylmethane diisocyanate, 2,4′-diphenylmethane diisocyanate, and mixtures thereof, and at least one first compound with plural active hydrogens, wherein said first pack has %NCO of 1% or greater, and (b) a second pack comprising at least one second compound with plural active hydrogens; at least one amine catalyst that is a diazabicyclo compound; optionally one or more additional catalyst that is an organometallic compound; and optionally one or more ingredient that is not an isocyanate, not a compound with plural active hydrogens, and not a catalyst; wherein compounds with plural active hydrogens in said second pack are all chosen from polyester polyols, polyether polyols, monoether polvols, alkane diols, and mixtures thereof; wherein the reactive mixture formed by admixing said first pack and said second pack is capable of curing in the absence of water; and wherein said reactive mixture comprises less than 3% solvent by weight based on the weight of said reactive mixture. 2. The composition of claim 1 wherein said reactive mixture, after curing, has density of 0.9 g/cm3 or greater. 3. The composition of claim 1 wherein said reactive mixture comprises less than 1% solvent by weight based on the weight of said reactive mixture. 4. The composition of claim 1, wherein the sole polyisocyanate used in forming the reaction product in said first pack is 4,4′-diphenylmethane diisocyanate. 5. The composition of claim 1, wherein said first pack has % NCO of 3% or higher. 6. The composition of claim 1, wherein said second pack additionally comprises one or more organometallic catalyst. 7. The composition of claim 6, wherein said organometallic catalyst in said second pack is one or more catalyst of the structure wherein M1 is a metal and wherein R2 is an alkyl group with more than 6 carbon atoms. 8. The composition of claim 6, wherein said organometallic catalyst in said second pack is zinc neodecanoate, bismuth 2-ethylhexanoate, bismuth neodecanoate, or a mixture thereof. 9. The composition of claim 1, wherein said second pack consists of at least one second compound with plural active hydrogens; at least one amine catalyst that is a diazabicyclo compound; and optionally one or more additional catalyst that is an organometallic compound.
