TESLAN® technology provides outstanding performance in extended 67 month immersion and natural outdoor weathering tests
The performance of TESLAN® ZN and TESLAN® AL Primers was demonstrated in extended 67 month immersion and outdoor weathering studies conducted at the US Army Corp of Engineers' Research Center (ERDC CERL) in Champaign, IL. Blasted steel test panels were coated with TESLAN® ZN and TESLAN® AL Primers, topcoated with TESLAN® Epoxy Polyamide Topcoat, and then subjected to long-term immersion in fresh and salt water solutions, as well as outdoor exposure. For control purposes, panels coated with a std. zinc-rich epoxy primer (MIL-P-24441, formula 159) and topcoated with a standard epoxy intermediate (MIL-DTL-24441, formula 152) were also tested. The TESLAN® systems can be seen to offer equal or enhanced scribe line protection versus the standard zinc rich epoxy systems (Note: discoloration of salt-water immersion panels is due to absorbed corrosion products coming from other panels under testing).

TESLAN® ZN Technology Demonstrated by US Army Corp of Engineers In Fort Bragg Storage Tank Coating Project
Through a collaborative partnership with the US Army Corp. or Engineers, the excellent performance of TESLAN® Coatings was demonstrated in a recent storage tank rehabilitation project at Fort Bragg, NC. This project involved the application of a three coat TESLAN® ZN Primer/TESLAN® Epoxy Intermediate/TESLAN® Urethane Topcoat system instead of the standard three-coat mil-spec MIL-DTL-24441 (formulas 159/152) zinc rich epoxy/intermediate epoxy/urethane system.
As reported by the project directors:
"Studies have demonstrated that traditional zinc-rich primer sacrificial coatings can provide the best protection to steel for 20–50 years or more. This demonstration/validation (dem/val) project supports the claim that the CNT/zinc hybrid primer can provide the same level of corrosion protection and be easier to apply when compared to traditional metallic zinc-richprimer systems."
"The project metrics were met or exceeded. This project has shown that the installation method with improved corrosion resistant coatings will provide the DoD with a means to cost effectively rehabilitate the outer metal surfaces of structurally sound fuel tanks and their associated piping. These coatings should extend the service life of all steel fuel and water storage tanks in all environments."
