Repair Amercoat 132E may be used to repair itself.

Surface Preparation New steel without pits or depressions should be abrasive blast cleaned in accordance with Sa 2 SIS 05 5900-1967 or ISO 8501-1. Previously painted or pitted steel, blast in accordance with Sa 2 . Note: Blast to achieve a 35 to 65 m profile as determined with Testex Press-O-Film tape or similar instrument. Remove abrasive residues and dust from surface. IMPORTANT - Apply Amercoat 132E as soon as possible after surface preparation to prevent any contamination. Do not leave blasted steel uncoated overnight. In case of contamination, remove contaminants. Spot blast steel if needed.

Application Equipment The following equipment is listed as a guide and suitable equipment from other manufacturers may be used. Adjustments of pressure and change of tip size may be needed to obtain the proper spray characteristics. AIRLESS SPRAY - Standard airless spray equipment, having a 28:1 or higher pump ratio and a fluid tip with a 0.43 to 0.58 mm (0.017 to 0.023 inch) orifice. CONVENTIONAL SPRAY - Industrial equipment With separate air and fluid pressure regulators, mechanical pot agitator and a moisture and oil trap in the main air supply line are recommended. MIXER - Use power mixer powered by an air motor or an explosion proof electric motor.

Overcoating For final use the Amercoat 132E is normally overcoated with PPG epoxy coatings or other suitable topcoats. Before overcoating, ensure surface is clean and free from zinc salts and other contamination.

Amercoat 132E

Application Procedure Amercoat 132E is packaged in the proper mixing proportions of resin and cure. Resin: 8.33 l (2,2 gal) in 10 l can Cure: 1.67 l (0,44 gal) in 2 l can 1. Flush equipment with Amercoat 18 before use. 2. Stir resin (in the larger container) to an even consistency

with a power mixer. 3. Add cure to resin and continue stirring for 5 minutes.

Note: Since the potlife is limited and shortened by high temperatures, do not mix more material than will be used in 8 hours at 20C (68F).

4. Thinning is normally not required for airless spray. For conventional spray, thin only as needed for workability, with up to 10 vol.% of Amercoat 18.

5. Stir during application to maintain uniformity of material. Apply a wet coat even, parallel passes. Overlap each pass 50% to avoid bare areas, pinholes or holidays.

6. Double coat all welds, rough spots, sharp edges and corners, rivets, bolts, etc.

7. Application at 85 m (3,4 mils) wet film thickness will normally provide 50 m (2 mils) dry film, or 125 m (5 mils) wet film for 75 m (3 mils) dry film

8. Check thickness of dry coating with a non- destructive dry film thickness gauge, such as Mikrotest or Elcometer. If less than specified thickness, apply additional material as needed.

9. Small damaged or bare areas and random pinholes or holidays can be touched up by brush. Repair larger areas by spray.

10. In confined areas ventilate with clean air during application and drying until all solvents are removed. Temperature and humidity of ventilating air must be such that moisture condensation will not form on surface.

11. Clean all equipment with Amercoat 18 immediately after use or at least at the end of each working day or shift. When left in spray equipment, Amercoat 132E will cure and cause clogging.

Before using the product, read the label on the can and consult the Material Safety Datasheet.
