1. A non-aqueous crosslinkable composition comprising: a polyurea having a functionality of equal to or greater than 2;an aldehyde or acetal or hemiacetal thereof; andone or more organic solvents;wherein the aldehyde is a polyaldehyde,wherein the polyurea is polyetherurea,wherein the composition, pr
1. A non-aqueous crosslinkable composition comprising: a polyurea having a functionality of equal to or greater than 2;an aldehyde or acetal or hemiacetal thereof; andone or more organic solvents;wherein the aldehyde is a polyaldehyde,wherein the polyurea is polyetherurea,wherein the composition, prior to crosslinking, has an aldehyde group to urea group molar ratio from 2:1 to 0.5:1; andwherein the non-aqueous crosslinkable composition means a crosslinkable composition in which a polymer is not dispersed in a continuous aqueous phase. 2. The non-aqueous crosslinkable composition according to claim 1, wherein the polyaldehyde comprises one or more cyclic, nonaromatic polyaldehydes having from 3 to 20 ring carbon atoms. 3. The non-aqueous crosslinkable composition according to claim 2, wherein the polyaldehyde is cyclohexanedicarboxaldehyde. 4. The non-aqueous crosslinkable composition according to any one of the preceding claims, further comprising a curing inhibitor. 5. The non-aqueous crosslinkable composition according to claim 4, wherein the curing inhibitor is chosen from water, an alcohol or a mixture thereof in an amount from 0.5 wt % to 20 wt %, based on the total weight of solids in the composition. 6. The non-aqueous crosslinkable composition according to claim 1, further comprising an acid catalyst having a pKa of less than 7. 7. The crosslinkable composition according to claim 1, wherein the crosslinkable composition is capable of reacting to cure at a temperature of equal to or less than 80° C. to form a crosslinked composition. 8. The crosslinkable composition according to claim 1, wherein the composition further comprises one or more additives selected from the group consisting of rheology modifiers, wetting agents, leveling agents, flow additives, stabilizers, surfactants, pigments, dispersants, and waxes. 9. A crosslinked composition comprising the crosslinking product of the crosslinkable composition according to claim 1. 10. A coating comprising the crosslinked composition according to claim 9. 11. The coating according to claim 10, wherein the coating is a concrete coating, composite coating, wood coating or a metal coating. 12. An article comprising a substrate and one or more coatings according to claim 10 associated at least with one or more surface of said substrate. 13. A process for producing a crosslinkable composition comprising: selecting a polyurea having a functionality of at least 2;selecting an aldehyde or acetal or hemiacetal thereof; andoptionally selecting one or more solvents;admixing the polyurea, aldehyde, and if present, the one or more solvents, thereby producing said crosslinkable composition;wherein the aldehyde is a polyaldehyde comprising one or more cyclic, nonaromatic polyaldehydes or one or more aromatic polyaldehydes,wherein the polyurea is polyetherurea,wherein the composition, prior to crosslinking, has an aldehyde group to urea group molar ratio from 2:1 to 0.5:1 andwherein the non-aqueous crosslinkable composition means a crosslinkable composition in which a polymer is not dispersed in a continuous aqueous phase. 14. The process for producing a crosslinkable composition according to claim 13, further comprising admixing an acid catalyst having a pKa of less than 7 with the polyurea, aldehyde and if present, the one or more solvents.
