High Build Coatings for Marine Corrosion Protection | HEGGEL
Solvent-free high build epoxy for marine corrosion protection in immersed splash and atmospheric zones
To combat the corrosion mechanisms observed in the offshore and marine environment, HEGGEL offers a coating pair for resistance against saltwater and UV exposure, HEGGEL Coat111 and Coat195. HEGGEL Coat 111 is a high-solids two-component epoxy applied direct to metal without a primer, coupled with Coat 195, a polyurethane topcoat used where UV and weather exposure would otherwise degrade an epoxy finish. This system builds a high film epoxy barrier for aggressive marine exposure while ensuring colour and gloss retention and UV resistance in the exposed zones so the system stays protective and fit for service across the different marine corrosion zones.
Key Advantages:
Direct-to-metal epoxy without primer: Reduces system complexity while still achieving exceptional adhesion on abrasive blasted steel to Sa 2.5 which supports reliable corrosion protection in aggressive offshore exposure.
Solvent-free, high build performance: HEGGEL Coat 111 is described as solvent-free with enhanced film build and it was applied to achieve about 700 microns DFT in a single layer, helping with durability and faster coating progress on fabrication scopes.
Resistance aligned to marine duty: HEGGEL Coat 111 is noted for resistance to seawater and high abrasion and erosion resistance, which matters in splash and tidal zones where wetting, drying and mechanical wear drive coating fatigue and underfilm corrosion.
UV and weather stability: Epoxies can discolour and degrade under UV, as such HEGGEL Coat 195 is used to protect the underlying epoxy and maintain colour and gloss retention in safety-critical areas.
Defined application windows for build quality: HEGGEL Coat 195 was applied at 80 to 120 microns DFT after Coat 111 reached touch dry cure, typically within 6 hours at 23degC, supporting controlled overcoating in workshop or yard conditions.
