P-403L Baking Phenolic CoatingGeneral Description: BakingPhenolicCoating General Chemical Resistance

This coating offers excellent immersion service resistanceto 92-98% sulfuric acid temperatures to 120°F. It has alsoshow excellent resistance to solvents, acids, salts and mildlyalkaline solutions. Please consult the Chemical Resistance

Guide, Sales Representative or Manufacturer for yourspecific requirements. Some examples are:

- Sulfuric Acid-Phenol- Anhydrous Chlorobenzene-Carbon Tetrachloride

Intended Usage: HERESITE P-403L material isa highly chemical resistant baked phenolic coatingdesigned for use in tank cars, railcars, and storagetanks where chemicals with a pH values less than 9are likely to be encountered.

FDA Status: This material meets the

requirements 0/21 CFR 175.300/or direct/oodcontact.

CAUTIO.: CONTAINS FLAMMABLE SOLVENTS. KEEP AWAY FROM SPARKS AND OPEN FLAMES. IN CONFINED AREAS WORKMEN MUST WEARFRESH AIR LINE RESPIRATORS. HYPERSENSITIVE PERSONS SHOULD WEAR GLOVES OR USE PROTECTIVE CREAM. ALL ELECTRICAL

EQUIPMENT AND INSTALLATIONS SHOULD BE MADE AND GROUNDED IN ACCORDANCE WITH THE NATIONAL ELECTRICAL CODE. INAREAS ~nERE EXPLOSION HAZARDS EXIST, WORKMEN SHOULD BE REQUIRED TO USE NONFERROUS TOOLS AND TO WEAR CONDUCTIVEAND NONSPARKING SHOES.

Surface PreparationSteel:

Immersion: A white metal blast in accordance withNACE #1 or SSPC-SP-63 Specifications.Non-immersion: A commercialblast is acceptable inaccordance with NACE #3 or SSPC-SP-6-63Specifications.

Surface proftle or anchor pattern should be 20-25%of the recommended dry ftlm thickness.

Equipment1. All spray equipment shallbe thoroughly cleaned

and free of old paint ftlm an other contaminants.2. Air supply shall be free of oils and water.3. Airlessspray equipment: 1800-2200 PSI liquid

pressure. Tip size from .017" to .021

Primer: Self priming on steel.

Thinning:

Suggested thinning at 77°F (25°C) is 10-15% basedon coating volume using Heresite S-215 solvent.This coating is designed for airless systems andsprays well at viscosities of 45 seconds on a Zahn #4.

Application:

1. Do not apply if the temperature is less than 5of(2°C) above the dew point.

2. Adjust the air pressure to approximately 60-75pounds pot pressure. Adjust spray gun by firstopening liquidvalve and then adjust air valve togive approximately an 8-12 inch fan.

3. Holding gun perpendicular to the surface at adistance of 12 inches, apply a mist bonding pass.

4. Allowto flash off for several minutes, but not'long enough to allowftlm to completely dry.

5. Apply 3 to 4 criss-cross multi passes maintaininga wet appearing ftlm.

6. Repeat Step #5 until desired ftlm thickness isobtained.

7. Allow60 minutes with ventilationprior tointroducing heat.

8. After the air dry period has elapsed, thetemperature should be raised approximately40°F (22°C) in increments of 30 minutes untilthe desired temperature is reached.

Bake ScheduleIntermediate Bake:

Metal Temperature to 175-200°F(93 °C) for 10 to 12 minutes.

Final Bake:

Metal Temperature to 400°F(204 °C) for 1 to 1 Y2hours.

Cleanup Solvent: S-215
