Description
Bitumen-modified epoxy — economical anticorrosive for bilge, void spaces, boot top
Did you know
- The Sigma Coatings brand, under which Sigmarine 28 is sold, originated from a merger in 1972, though its heritage traces back to 1722 with Jan Pieterszoon Schoen in the Netherlands. PPG acquired SigmaKalon (which included Sigma Coatings) in 2008. A product data sheet for Sigmarine 28 is dated July 2009, suggesting it was available by then.
- Sigmamarine 28 is positioned as a one-component, quick-drying, high-build, multi-purpose zinc phosphate primer within PPG's marine coatings portfolio, specifically designed for onboard maintenance of above-water areas. It is compatible with various one and two-component topcoats, including PPG Sigmarine One 648.
- This primer is chosen for its ease of application, quick-drying properties, and good anticorrosive performance, making it suitable for efficient onboard maintenance. Its surface tolerance allows for effective use even with less intensive surface preparation.
