Product Description
A two-pack, modified epoxy designed as a tie coat or sealer on epoxy anticorrosive systems in order to improve the adhesion of subsequent antifouling systems. It can also be recoated with other Navimar finishing systems, making it a perfect second coat in a keel-to-rail anticorrosive system.

(1) The surface should be dry and free from contaminants prior to overcoating. If the maximum recoating time is exceeded it may be necessary to roughen the surface to ensure intercoat adhesion. When recoating with single-pack products, it is advised to recoat before Navipox TC 206 is fully cured. When in doubt, consult your nearest Navimar office.
Surface Preparation
Steel: Oil and grease should be removed by solvent cleaning according to SSPC-SP1. Remove weld spatter and smooth weld seams and sharp edges as applicable. Abrasive blasting: min. Sa2 – ISO 8501:1. Apply Navipox TC 206 immediately after the steel surface has been blasted and the quality of surface preparation has been approved. Navipox TC 206 may also be applied on suitable Navipox anticorrosive systems. Ensure that primed substrates are dry and free from salts and other contaminants.
Repair: Existing paint systems should be dry and free from salts and other contaminants. Corroded and/or damaged areas should be blast cleaned to ISO-Sa2 or power tool cleaned to ISO-St3 or hydroblasted to DW 3 according to STG-2222.
Recommended Paint System
Navibond 467 (Masterbond Aluminium): 1 x 125–150 µ dft.
Navipox TC 206: 1 x 100–125 µ dft.
Subsequent coating with Navimar finishes or appropriate Navimar antifouling systems.
Worldwide Availability
