Coatings supplier Hempel has launched Hempaguard, a new hull coating concept for the shipping industry, which offers both resistance to fouling during idle periods and significant fuel savings.
The technology, dubbed ActiGuard, has been five years in development. Hempaguard is available as two separate products: Hempaguard X5 and X7.
ActiGuard
ActiGuard integrates silicone-hydrogel and full diffusion control of biocides in a single
coating. Surface retention of the biocide activates the hydrogel, which effectively holds fouling organisms at bay, cutting friction to a minimum while utilising a minimum amount of biocide.
Fouling Resistance when Idle
Company tests indicate fouling resistance of up to 120 days during idle periods plus fuel savings of six per cent on average. In addition, Hempaguard is said to retain its effectiveness when switching between slow and fast steaming anywhere in the world.
Performance Guarantee
Hempel is convinced of the product’s performance and therefore offers a performance satisfaction guarantee contract for vessels complying with a full Hempaguard X7 specification. If customers are not satisfied, Hempel will pay for the conversion to conventional antifouling.
