Cross linking chemically links together what ever molecules are present, in the typical case a low molecular weight (smaller length) polymer. The result is an insoluble material (might soften it with solvent but never dissolve it), and typically a harder material, and maybe a tougher material........ for reasons of more entanglement, and other reasons that are too complicated to readily explain with my pedestrian typing skills. Cross linking makes the resultant structure more rigid.

Often this linking chemistry uses the formation of urethane bonds, or in the case of epoxy, bonds generated by the epoxy molecules in the clear component. The naming is Byzantine. In the case of "urethane" the name says what kind of chemical bond forms. In the case of "epoxy" the name says what kind of chemical is used to make the bond. The bottom line is that names in finishes and adhesives are near useless for any predictive purpose.
