Standard liquid anti-fouling additives (e.g., water and stain repellents): When stored in a sealed container in a cool, well-ventilated area, the shelf life is typically one year. Once opened, the product should be used as soon as possible and resealed properly to prevent moisture exposure.
Raw materials for anti-fouling coatings: Under compliant storage conditions, anti-fouling performance remains largely unaffected for up to one and a half years, allowing for normal use.
General-purpose chemical anti-fouling raw materials: The shelf life generally ranges from 3 to 10 years; however, some specialized anti-corrosion raw materials may have a shorter shelf life, which should be determined based on specific product characteristics.
For all anti-fouling raw materials, it is recommended to refer to the official product specifications or instructions for the actual shelf life.
