GENERIC TYPE: A two package, amine cured, cold set epoxy

RECOMMENDED USAGE: Heresite CSE-6000 is primarily used for lining tanks, coating process equipment, and as an industrial maintenance material. It is easily applied to metal, concrete, and wood.

Heresite CSE-6000 Series meets the requirements of the U.S. Federal Register, Food & Drug Regulations, Title 21, Chapter 1, Paragraph 175.3000.

CHEMICAL RESISTANCE GUIDE:

Force curing is required when exposure is severe.

COVERAGE: Theoretical Coverage --- 818 square feet per gallon per mil. (At 7 mil DFT average coverage would be 93 square feet per gallon. This includes a 20% loss factor.)

Recommended total dry film thickness is as follows:

Environment	Dry Film Thickness	No. of Coats
Immersion	12-15 Mils	2
Highly Corrosive Fumes	12-15 Mils	2
Mildly Corrosive Fumes	7-10 Mils	2
Maintenance	6-8 Mils	1

SURFACE PREPARATION: Remove all oil, grease, and other contaminants. All seams should be continuously welded, weld splatter removed and all edges radiused. (See Bulletin No. 113. "Fabrication Specifications.")

STEEL:

IMMERSION: A white metal blast is required in accordance with NACE #1 or SSPC-SP-5-63 specifications.

NON-IMMERSION: A commercial blast is acceptable in accordance with NACE #3 or SSPC-SP-6-63 specifications.

Surface profile or anchor pattern should be 20 to 25% of the recommended dry film thickness.

CONCRETE: Remove protrusions by sanding or grinding. Concrete must be cured 28 days at 70°F (21°C) and 50% relative humidity.

IMMERSION: Dry abrasive blast to open all voids. Blow or vacuuil off residue.

NON-IMMERSION: Surfaces must be acid etched or abrasive bl~sted to remove laitance.

EQUIPMENT:

1. All spray equipment shall be thoroughly cleaned and be free of old paint film and other contaminants.
2. Use standard production type spray guns:

   Guns	Fluid	Air
   DeVilbiss JGA-502	E	704
   Binks #62	66-SS	66-SD
   Graco P800	04	02

3. Air supply shall be uncontanlinated.
4. Airless spray equipment: 1500-1800 PSI liquid pressure. Tip size from .015" to .019". Thinning requirements are less than for conventional spray.

MIXING: Stir Part A thoroughly, then stir Part B thoroughly. Add the contents of Part B to the container of Part A. Mix thoroughly and allow the mixed material to age 30 minutes before using. Mixed material must be used within 8 hours.

PRIMER: Self priming on steel. On concrete or wood a primer coat is recommended, consisting of 1 part coating to 2 parts solvent.

THINNING: The type and amount of thinner required is dependent upon temperature, ventilation, humidity, spray equipment used, and desired film thickness. Suggested thinning at 75°F (24°C) is 20-30%. Heresite S-330 solvent is the fastest drying. It is recommended for normal applications. Heresite S-310 solvent can be used when a slower drying solvent is required. Heresite S-3000 solvent is the slowest evaporating. (If immersion service is expected after using S-300 solvent, the coating must be force cured following a schedule listed below.)(Viscosity of 40-45 sec.-- Zahn Cup 2.)

APPLICATION:

1. Do not apply if temperature is less than 5°F (2°C) above dew point.
2. Adjust air pressure to approximately 80 pounds at the gun and provide 15-20 pounds pot pressure. Adjust spray gun by first opening liquid valve and then adjust air valve to give approximately an 8" to 12" fan.
3. Holding gun perpendicular to the surface at a distance of 12", apply a mist bonding pass.
4. Allow to flash off for several minutes, but not long enough to allow film to completely dry.
5. Apply 3-4 criss-cross multi-passes maintaining a wet appearing film.
6. Repeat Step #5 until desired film thickness is obtained.
7. Clean equipment immediately with Heresite S-310 or S-330 solvent.
8. Let first coat air dry with ventilation for approximately 16 hours, but not longer than 72 hours.
9. For second coat, repeat Steps #1 through #7.
10. Coating should be final cured according to following schedule:

    70°F(21°C) -- 7 days
    50°F(10°C) -- 14 days

FORCE CURE:

1. If force curing is required, air dry with ventilation for approximately 2 hours.
2. After the air dry period has elapsed, the temperature should be raised in 40°F (22°C) increments every 30 minutes .
3. Hold at desired curing temperature according to following schedule to effect final cure:

   130°F (55°C) -- 18 hours
   160°F (71°C) -- 4 ½ hours
   200°F (93°C) -- 1 ¾ hours
