Surface Preparation:
Surface must be clean, dry, and in sound condition. Remove all oil, dust grease, dirt, loose rust, and other foreign material to ensure adequate adhesion.

Iron & Steel Substrates:
Remove all oil and grease from surface by solvent cleaning per SSPC-SPI. Minimum surface preparation is commercial blast cleaning per SSPC-SP6. For better performance, use near White Metal Blast Cleaning Per SSPC-SP10. Blast clean all surfaces using a sharp, angular abrasive for optimum surface profile (2 mils). Remove all weld spatter and all round sharp edges by grinding to a minimum " radius. Prime any bare steel the same day as it is cleaned or before flash rusting occurs.

Aluminum Substrates:
Remove all oil, grease dirt, oxide and other foreign material by solvent cleaning per SSPC-SP1.

Application Conditions:
Temperature:             50 F Minimum, 100 F Maximum (Air, Surface and Material) At least 5 F above dew point
Force Drying:             45-60 Minutes @ 140 F For Dry Hard
Relative Humidity:      85% maximum

Application Equipment:
The following is a guide. Changes in pressures and tip sizes may be needed for proper spray characteristics. Always purge spray equipment before use with listed reducer. Any reduction must be compatible with the existing environmental and application conditions.

Conventional Spray:
Unit 30:1 Pump
Pressure 2400-2800 psi
Hose 1/4" ID
Tip 009"-.015"
Filter 60 Mesh
Reduction Not Recommended

Airless Spray:
Gun DeVilbiss MBC510
Fluid Cap FF
Air Cap 797
Atomization Pressure 50-60 psi
Fluid Pressure 10-15 psi
Reduction Not recommended

Reducer/Clean Up: MIL-P-81772, Type-II

Application Procedures:
Mix contents of both Part A & B thoroughly with power agitation. Make certain no pigment remains on the bottom of the can. Then combine three parts by volume of Part-A with one part by volume of Part-B. Thoroughly agitate the mixture with power agitation. After mixing, pour through a 60-mesh screen. Allow the material to sweat-in as indicated below prior to application. Re-stir before using.

Performance Tips:
Stripe coats all crevices, welds and sharp angles to prevent early failure in these areas. When using spray application, use a 50% overlap with each pass of the gun to avoid holidays, bare areas, and pinholes. If necessary, cross spray at right angle.

Spreading rates are calculated on volume solids and do not include an application loss factor due to surface profile, roughness or porosity of the surface, skill and technique of the applicator, method of application, various surface irregularities, material lost during mixing, spillage, over thinning, climatic conditions, and excessive film build.

Excessive reduction of material can affect film build, appearance, and adhesion. Do not apply the material beyond recommended pot life

Do not mix previously catalyzed material with new. In order to avoid blockage of spray equipment, clean equipment before use or before periods of extended downtime with Epoxy Thinner MIL-P-81772, Type-II

Safety Precautions:
(A) Use normal precautions such as gloves, facemasks.
(B) Adequate ventilation must be maintained.
(C) Explosion proof lights & electrical equipment.
(D) Non-Sparking shoes & tools for workers in area.
(E) This product contains flammable materials. Forbid all flames, smoking and welding in work area.
(F) Avoid breathing of vapor, contact with skin or eyes. If product comes in contact with skin or eyes, wash thoroughly with water and obtain medical attention.
