Offshore Paint

Primer is based on high anti-corrosion primer. Commonly used primers include epoxy zinc-rich primer, inorganic zinc silicate primer, and epoxy anti-rust primer. Zinc rich primer is an organic or inorganic coating containing a high proportion of zinc powder as a filler. The zinc rich coatings use high-build epoxy coating with a volume solid content of more than 70%, strong adhesion, and surface tolerance.

The function of the intermediate coat and topcoat is to provide a protective layer for the primer, slow down and limit the penetration of water vapor, oxygen and chemically active ions. Commonly used topcoats in the marine offshore platforms include aliphatic polyurethane paint and polysiloxane coatings. Aliphatic polyurethane coatings are often used in conjunction with zinc-rich primers and high build epoxy intermediate coat. The polysiloxane coating is directly matched with the zinc-rich primer coating. Epoxy polysiloxane coatings have stronger corrosion resistance, and acrylic polysiloxane coatings are better in decoration property.
