Sea~Barrier Altra

Sea~Barrier Altra is a new, patented silyl acrylate polymer based antifouling designed to protect hulls from marine growth through an outstanding controlled self polishing hydrolysis action - the silyl acrylate, cuprous oxide and co-biocide combination provides exceptional multi-season protection. Extensive testing and sea trials show Sea~Barrier Altra to be providing exceptionally cost effective, long term protection for commercial & deep water use. Ideal for work vessels of virtually any description such as fishing fleets, tugs and barges, container ships, passenger and vehicle ferries, and vessels trading in deep sea or coastal waters.

Features & Benefits

  • Suitable for both maintenance docking and new builds
  • Improved performance at lower builds
  • Latest generation controlled hydrolysis Silyl Acrylate Polymer technology
  • Micro fine, engineered cuprous oxide technology
  • Developed & tested over several years, and proven in the most severe marine conditions
  • Highly predictable & stable self polishing hydrolysis action maintains full-time antifouling activity, reducing friction and drag
  • Improved adhesion to primers, build coats and existing antifoulings being repainted and fully compatible when applied over Sea~Barrier 1000 and 3000
  • Very good static exposure performance
  • Superior mechanical strength – avoids cracking & peeling
  • Controls common types of fouling for extended periods* & provides an easy to maintain surface between dockings (film build dependant - *see Disclaimer under Limitations section)
