marine & protective coatings
Marine & protective coatings are applied to metal and concrete substrates to provide corrosion resistance and fire protection and to secure metal structures, particularly from salt water and other environmental impacts. Durability is also a high priority. Marine vessels, offshore supplies, yachts, and containers ships are a few application areas.

Researchers at Evonik are working on a variety of alternatives for traditional biocide-containing coatings: from a new silicone epoxy hybrid resin system, whose anti-adhesive properties make it difficult for micro-organisms to stay attached to the hull, to amphiphilic polymers that “hide” the hull’s surface and prevent attachment/settlement, to a hydrophilic structurally modified AEROSIL® that interacts with copper oxide to create a tougher and more resistant coating film.
Jane Goh, senior chemist at Evonik’s research hub in Singapore, discusses the challenges associated with formulating environmentally friendly, high-performance industrial coatings.
