International. A set of multifunctional thiol-ene polymer resins cured with UV was prepared from monomers containing thiolactone and different amine compounds. By applying the derived polymers to steel, the researchers found four beneficial properties.
The aminolysis of thiolactone allowed the introduction of different side chains and cross-linking agents into the polymers.
The transition temperature of the polymer glass varied between 22 and 90 ◦ C, depending on the type and molar proportion of amine-containing compounds relative to the monomer. The properties of UV-cured thin films were screened using standardized coating assays, including pencil hardness, impact resistance, and cross-weft adhesion.
Thiolactone-derived polymer films exhibited high transparency of 90%, pencil hardness in the range of 3B-HB, high impact resistance of> 2 kg m, and good adhesion to steel in dry conditions.
