Thermoplastic polymers

Thermoplastic glues including hot-melt adhesives cure reversibly as they cool, like the gelatin and keratin glues listed above. They frequently don't emit volatiles unless overheated. * Styrene acrylic copolymer – e.g. "No More Nails"

Thermosetting polymers

Thermosetting glues or thermosets cure irreversibly by polymerization. The polymerization can be triggered by heat or other radiation, or high pressure or a
