Based on the previously discussed storage and usage requirements for various categories of anti-fouling raw materials, shelf lives vary significantly depending on the type. Details are as follows:
Textile anti-fouling raw materials: Conventional fluorocarbon-based "three-proof" (water, oil, and soil repellent) finishing agents typically have a shelf life of 6 months whereas some high-end easy-clean finishing agents can last up to 2 years when stored in sealed containers in a cool place.
Marine anti-fouling paint raw materials: Materials such as zinc-acrylate self-polishing resins and finished marine anti-fouling paints have a shelf life of 12 months under standard sealed storage conditions.
Leather anti-fouling raw materials: Perfluoro-hydroxy-carbosilicon copolymer-based water and oil repellents have a shelf life of 1 year when stored in sealed containers in a cool place.
Cement-based anti-fouling raw materials: Some auxiliary cement-based anti-fouling products have a standard shelf life of only 3 months; if this period is exceeded, they must pass inspection before use.
