Coatings need Ketjenflex®


Axcentive is taking a renewed look at coatings markets. Our products such as Ketjenflex® 8, Ketjenflex® 9, Ketjenflex® 12, Ketjenflex® CP and Ketjenflex® MH are not as universally known by this industry as we may have thought.

An important step during the coating of a substrate is the film formation. The Axcentive® Ketjenflex® range is specifically designed to aid superior film formation to obtain smooth, shiny films with no surface defects. Among the application areas where the Ketjenflex® range performs outstandingly are: ablative antifouling coatings, PVC plastisols, nitrocellulose lacquers and acid cured wood coatings.

Antifouling coatings form an important finish on every ship. Pleasure yachts, cargo boats or cruise ships all need some kind of antifouling coating to prevent microbiological growth. Container vessels coated with proper antifouling are known to be much more fuel efficient. For example, up to 20% less fuel can be consumed when the ship is coated with ablative or erodible antifouling coatings.

Ketjenflex® 8 is typically used in ablative coatings based on polyamide or collophonium resins that include copper oxide as the active biocide species. Ablative antifouling coatings work on the principle that during its service life the coating is slowly eroded releasing a constant stream of antimicrobial copper oxide. Ketjenflex® 8 is an important component as it provides plasticization and adhesion and adds water exclusion properties.

Plastisols are high-build thermoplastic coatings based on polyvinylchloride (PVC) in a plasticizer. PVC plastisols based on Ketjenflex® 12 can be used as coating in various applications. Since Ketjenflex® 12 stands out by its toxicological profile, it is declared safe for use in coatings for children’s toys. For this reason plastisols based on Ketjenflex® 12 are especially suitable for toy coatings and for coatings for medical devices.
