This is a two component, high performance Epoxy Polyamide Coating recommended for use as an intermediate / undercoat for WC topcoats. It is designed for application to properly prepared and primed steel, aluminum, or fiberglass and is suitable for interior or exterior surfaces.
EP151 is formulated to provide a hard, durable, chemically resistant, non- porous coating as an intermediate coat, providing additional film build or protection, for subsequent high performance finish coats, such as the WC line of topcoats. This Epoxy Coating meets all current VOC requirements and is lead free. It also meets the requirements of MIL-P-24441/2C.

Good surface preparation is essential to a satisfactory coating system. Surfaces to be coated should be clean and dry. Remove all oil, grease, mildew or other contamination by solvent or detergent cleaning or other effective means.
Apply in good weather when air and surface temperature are above 50�F and surface temperature is at least 5° F above the dew point. For optimum application properties, material should be between 70° to 100°F prior to mixing and application. Maintain unmixed material in closed containers in protected storage at 40° to 100° F.
For best performance, application to abrasive blasted surface is recommended. "Commercial Blast Cleaning" SSPC-SP6 is recommended as the minimum. For immersion service "Near White Blast Cleaning" SSPC-SP10 is considered minimum. Proper blast media and blasting equipment shall be used to produce an average profile depth of 2.5 mils minimum. Do not reuse abrasive media. Remove blasting dust and grit from surfaces before painting. Blasted surfaces should be coated within 8 hours after blasting or before rusting or other contamination of the surface occurs. If blasting is not feasible, remove rust by "Hand or Power Tool Cleaning" (SSPC-SP2 or SP3).
Remove oil and prime with Vinyl Wash Pretreatment Primer.
Clean thoroughly and etch with phosphoric acid based cleaning solution. Rinse well and allow to dry.
Must be clean, dry, properly cured and free from all surface contaminants. "Brush Off Blast" (SSPC-SP7) to provide an etched surface and to remove contaminants and laitance. Remove dust before coating.
Must be clean, dry, properly cured and free from all surface contaminants. Hand or mechanically sand entire surface until smooth and to remove any gloss.
Solvent wipe surface with MAK, MIBK, MEK or Acetone, turning rag continuously to remove all sanding dust. Repeat if necessary to assure a clean dry surface.
This is a two component coating supplied in two containers as a unit.
Always mix a complete unit in the proportions supplied.
(1) Mix the contents of 21EP151 (Component A) thoroughly with a power agitator.
(2) Mix the contents of 21EP151 (Component B) thoroughly with a power agitator.
(3) Combine the entire contents of Component A and Component B and mix
thoroughly with a power agitator.
Allow a 1hour induction time@70� F before using the coating.
Usable pot life depends on the temperature of the material.
Refer to Pot life section on front page. Agitate before use.
Occasional stirring during use is suggested.
Material is supplied at spray viscosity and normally requires no thinning. If thinning is necessary thin with up to 10% with 21AL50 Blended Thinner per gallon.
Spray application is preferred for proper film build and best performance. Brush application is acceptable for touch up. Roller application may require special care to prevent bubbling and may require more than one coat to attain proper film thickness. Apply at 5.2 mils wet film thickness to achieve 3.0 mils dry film thickness, unthinned.
Conventional spray - DeVilbiss MBC gun with E tip and 30 air cap or equal at 40-60 psi atomizing pressure and 10-25 psi pot pressure, 3/8" ID product fluid hose, double regulated pressure pot with oil and moisture separator. Airless spray - Minimum of 30:1 ratio pump,.015 to .019 tip, 3/8 ID Teflon material fluid hose.
During lunch, breaks or any period of work stoppage, material should be removed from hoses and equipment. Release pressure from equipment and flush hoses and equipment with 21AL50 Blended Thinner, MEK, MIBK or Xylene. Do not repressurize equipment until ready to resume work.
Clean all equipment immediately after use with 21AL50 Blended Thinner, MEK, MIBK or Xylene. Completely flush all spray equipment with this solvent. Occasional flushing of spray equipment during the course of the working day helps prevent buildup and possible clogging.
Safe storage, handling and use dictate that adequate health and safety precautions e observed with this product and any recommended thinners. User is specifically directed to consult the current Material Safety Data Sheet for this product as well as precautions contained on product labeling.
