Marine Coatings Chemicals
Marine coatings chemicals range from antifouling biocides (zinc pyrithione, cuprous oxide) and rosin-based ablative resins to high-build epoxy intermediate coats and aliphatic polyurethane topcoat resins. Our portfolio serves shipyard coating formulations, offshore structure protection, and leisure marine refinish products.

Frequently Asked Questions — Marine Coatings Chemicals
What are the main types of antifouling chemistry?
Self-polishing copolymer (SPC) antifoulings use acrylic or silyl methacrylate copolymers that hydrolyze in seawater, releasing biocides at a controlled rate. Hard antifoulings use a non-ablating binder with high biocide loading for longer service intervals. Biocide-free silicone fouling release coatings are the premium eco-alternative.
Which epoxy resins are preferred for marine corrosion protection?
Liquid bisphenol A/F epoxies with polyamide or amine hardeners are standard for marine anticorrosion primers and intermediate coats. High-build formulations at 200–400 µm DFT are applied in two to three coats. Epoxy mastic variants with higher PVC offer surface-tolerant properties for maintenance over existing coatings.
What topcoat systems provide long-term gloss retention on marine superstructures?
Two-component aliphatic polyurethane (2K PU) topcoats based on acrylic polyol + HDI isocyanate give the best UV and chemical resistance for above-water marine applications. High-solids formulations are preferred to minimize VOC. Waterborne PU dispersions are gaining adoption as regulations tighten in shipyards.
What pigments and biocides drive modern antifouling formulations?
Cuprous oxide remains the dominant biocide at 30–50% by weight in copper-based antifoulings. Co-biocides (zinc pyrithione, copper pyrithione, tralopyril) add efficacy against soft-fouling. Zinc oxide acts as a buffer to control hydrolysis rate in self-polishing copolymer (SPC) systems. Copper-free antifoulings rely on organic booster biocides (DCOIT, medetomidine) for environmentally sensitive markets.
What does IMO PSPC require for ballast tank coatings?
The IMO Performance Standard for Protective Coatings (PSPC) requires a two-coat epoxy system at 320 µm nominal DFT with stripe coats on edges and welds, applied to Sa 2.5 surface preparation, in a light color for inspection visibility. Type approval testing per IMO MSC.215(82) confirms 15-year service through accelerated aging, condensation, and salt-spray testing on full-scale panels.
What anti-fouling certifications and regulations apply globally?
IMO MEPC.207(62) Anti-Fouling Systems Convention prohibits TBT-based antifoulings worldwide since 2008. EU Biocidal Products Regulation (BPR 528/2012) registers all biocides for marine use. China requires GB/T 31412 compliance. US EPA registers each booster biocide under FIFRA. Antifouling formulations must therefore use approved biocide combinations that pass leach-rate, efficacy, and ecotoxicity testing for each market.
