Strippable coatings are widely used for radiological surface decontamination owing to their high removal efficiency, 

simple application, and reduced secondary waste generation. Conventional strippable coatings generally rely on solvent 

evaporation and long drying times to form peelable polymer films, which limits their applicability in emergency response 

and low-temperature environments. Recent studies have focused on overcoming these limitations by developing advanced 

strippable coatings with rapid film formation and alternative crosslinking mechanisms. These include self-stripping brittle 

coatings, photo-crosslinkable systems, non-drying hydrogel-based coatings utilizing reversible chemical bonds, and formulations

designed for sub-zero operation. Such approaches enable faster immobilization and removal of radioactive contaminants

while improving field applicability. This review summarizes the recent progress in strippable coating technologies 

for radiological surface decontamination, with emphasis on film-formation mechanisms, decontamination principles, and 

application conditions. Unlike previous reviews that primarily categorize coatings by material type, this work provides a 

mechanism-oriented framework linking formulation strategies with film formation behavior and field applicability. Key 

challenges and future directions toward rapid, non-drying, and environmentally compatible decontamination coatings are 

also discussed.
