Description
Epoxy tie coat — compatibility bridge for overcoating systems
Did you know
- Sigma Coatings, a brand with heritage dating back to 1722 through Pieter Schoen & Sons, merged in 1972 to form Sigma Coatings, which was later acquired by PPG in 2008. The Sigma Alphagen 230 is part of the broader Sigma Alphagen series of antifouling coatings.
- The Sigma Alphagen 230 is a low friction linear polishing antifouling coating within PPG's Sigma Coatings range, designed for deep-sea vessels. Other Alphagen products include Alphagen 240 and Alphagen 650, which also offer antifouling properties.
- The Sigma Alphagen 230 is chosen for its TBT-free, self-polishing antifouling properties, which provide effective protection against shell and weed fouling for extended periods. It is suitable for high and medium-activity deep-sea vessels such as tankers, bulkers, general cargo, and container ships.
