Coatings manufacturer Hempel has rolled out Hempatop Repel 800, a new flexible two-coat water repellent coating for offshore assets and installations that is designed to offer enhanced corrosion protection by actively repelling water from the coated surface.
The first volumetric water repellent topcoat on the market, Hempatop Repel 800 (used in combination with Hempel's patented Avantguard technology activated zinc primer Avantguard 770 as the first coat) delivers improved flexibility and crack resistance, increased adhesion retention and minimizes corrosion, according to Hempel, who said the two products work together to create a robust anti-corrosive system.
The manufacturer noted that this two-coat system requires one coat less than standard protective coatings solutions for offshore installations and lasts significantly longer, simplifying the construction and maintenance processes of offshore assets, and reducing costs for owners.
Oriol Osso, Head of Energy, Group Product Management, Hempel, explained, "We have found that traditional three-coat systems used for offshore structures regularly show signs of early coating failure. This is primarily due to water ingress through the coating system, stress induced micro-cracking and/or mechanical damage. This leaves asset owners with unsustainable maintenance costs. Our new Hempatop Repel 800, used in combination with our innovative activated zinc primer Avantguard 770, simplifies the process and addresses all these challenges. Assets can now be protected for longer, reducing the frequency and cost of ongoing maintenance."
The Hempatop Repel 800 system is designed to be easily applied with conventional or airless application equipment and can be applied in one day, reducing the man-hours required for applicators offshore, Hempel said.
Hempel said Hempatop Repel 800 is available now through its technical representatives worldwide.
