Amerlock Series High-solids epoxy coating

1 Product Data/Application Instructions Low VOC High-performance general maintenance coating for new or old steel Cures through wide temperature range Self-priming topcoat over most existing coatings Can be overcoated with wide range of topcoats Compatible with prepared damp surfaces Compatible with adherent rust remaining on prepared surfaces 5 mils or more in a single coat Resists high humidity and moisture Temperature resistance to 450 F on insulated or uninsulated surfaceswhen mixed with amercoat 880 glass flake additive Can be applied to substrates with temperatures up to 250 FAmerlock s low solvent level meets VOC requirements, reducesthe chances for film pinholing and solvent entrapment at thesubstrate- coating interface, often a major cause of coatingfailure with conventional epoxies and lower solids 400 is available in a variety of colors, includingaluminum, and therefore does not require a topcoat.

2 For extendedweatherability or special uses, a topcoat may be UsesAmerlock 400 is used in those areas where blasting is impractical orimpossible. As a maintenance coating , Amerlock 400 protects steelstructures in industrial facilities, bridges, tank exteriors, marineweathering, offshore, oil tanks, piping, roofs, water towers and otherexposures. Amerlock 400 has good chemical resistance tosplash/spillage, fumes and immersion in neutral, fresh and salt water(see resistance table).

Maximum recoating timeis highly dependent upon actual surface temperatures - not simplyambient air temperatures.

6 Surface temperatures should be monitored,especially with sun-exposed or otherwise heated surfaces. Higher surfacetempertures shorten the maximum recoat : If maximum time is exceeded, roughen surface. For topcoats(finish coats) not listed, see Product Data sheet for specific topcoattime PreparationCoating performance is, in general, proportional to the degree ofsurface preparation. Abrasive blasting is usually the most effective andeconomical method. When this is impossible or impractical, Amerlock400 can be applied over mechanically cleaned surfaces. All surfacesmust be clean, dry and free of all contaminants, including salt 400 may be used over most types of properly prepared andtightly adhering coatings. A test patch is recommended for use overexisting Remove all loose rust, dirt, moisture, grease or other contami-nants from surface.

For immersion service dryabrasive blast SSPC-SP10. For high-heat service on uninsulatedsubstrates, abrasive blast per SSPC-SP6. For insulated substrates,abrasive blast per SSPC-SP10.
