Ship coating is a general term for coatings that are used in various parts of ships and marine engineering structures to meet the requirements of preventing seawater, marine atmospheric corrosion, marine organism adhesion, and other special requirements.
The bottom paint of the ship is also the paint used for the underwater parts of the ship, including: ship paint antirust paint and ship bottom antifouling paint. Among them, the anti-corrosion paint for ship bottom includes: asphalt anti-rust paint for ship bottom, chlorinated rubber anti-rust paint for ship bottom, epoxy asphalt anti-rust paint for ship bottom; antifouling paint for ship bottom includes: dissolving type-bituminous cuprous oxide antifouling paint; contact Type-chlorinated rubber, ethylene cuprous oxide antifouling paint; diffusion type: organic tin antifouling paint; self-polishing antifouling paint-organic tin polymer antifouling paint.
The ship primer is a kind of paint that is applied below the ship's waterline and is immersed in the bottom of the underwater ship for a long time. The main purpose is to prevent seashells and insects from attaching to the bottom of the ship, reduce the corrosion of the ship's hull by sea water, and prevent rust. These paints are generally red, so the bottom of the ship is mostly red.
