Polymers can be hardened by a process known as vulcanization (curing of elastomers), a chemical process that involves a curing agent and heat.
According to Wikipedia, for the vulcanization of rubber, sulfur is used, whilst for neoprene (polychloroprene) metal oxides are used (MgO, ZnO and somtimes Pb3O4).
I wonder if a polymer coating (assumed neoprene) that was altered by cleaning alcohol (isopropanol) and became tacky/sticky, can be hardened again by applying a suitable hardening agent and heating with a simple temperature controlled hot air station. If yes, which the temperature ranges and which precautions?
Envisaged application: restoring the coating of a laptop palmrest that became tacky/sticky.
