Generally, there are epoxy (two-component), chlorinated rubber (one-component), alkyd (one-component), aliphatic polyurethane (two-component) and Wuxi self-polishing antifouling paint (one-component). The two components of these coatings must be mixed in proportion with component A\B according to the product description, and can only be used after a period of uniform curing. The single component must be stirred evenly with a blender before it can be used.
