Anticorrosive primer for harsh environments
Around 500 ships, operated by Solvang ASA , BW Fleet Management (Bergesen dy ASA), Høegh Fleet Services AS., Frontline Ltd., V-Ships Norway, Golar LNG, Klaveness Group, Fred Olsen Marine, Kr. Gerh. Jebsen Skipsrederi AS, Westfal-Larsen Management AS, Seatrans ANS, Solstad Offshsore, Singapore have tested and subsequently become regular users of Active Rust Primer 662 SG.
Where? In ballast tanks, in various wet rooms, on demanding outside surfaces and so forth. More and more ships are incorporating this metal primer into their maintenance systems.
Adhesive primer to use on wet surfaces
“Active Rust Primer 662 SG” (under label of the ENVIRO-COAT 2000 products) has proven its quality as an outstanding base coat within existing paint systems. New polymer technology has produced highly reactive binders which ensure good penetration and adhesion properties.
The primer offers a remarkable combination of hardness and elasticity, but its two most important characteristics are that it works well in wet environments (the curing process effectively removes moisture from the steel), and that it reacts chemically with surface rust to render it inactive.
Metal primer with enhanced salt tolerance
Paint coats can normally handle up to 20 mg of salt per square meter. It is when salt concentrations exceed this level that the greater problems occur. Tests show that even after hosing down with fresh water, concentrations significantly higher than this are common on rough surfaces.
When a highly-fluid water-based primer penetrates surface cavities, it is presumed that water-soluble salts are reduced and rust formation is inhibited. Test panels with moisture and salts applied and then placed in a condensation chamber display conspicuous differences with and without primer in the system.
