PROUCT USES
Specific areas include structural steel, tanks, pipes, vessels, structural steel, equipment, pipe lines, etc., in chemical processing plants, pulp and paper mills, sewage and waste water treatment facilities, fertilizer plants, petroleum refineries, electric generating stations, coal handling operations, marine installations, etc.
SURFACE PREPARATION
Remove all dirt, grease, oil, soil, chemical contaminants, and other matter before any mechanical preparation. High pressure water cleaning is recommended. Prepare and paint only clean surfaces in accordance with Steel Structures Painting Council (SSPC) or National Association of Corrosion Engineers (N.A.C.E.) specifications.
1. Steel
a. Sand Blast - Best
Sand Blast to a “Commercial” ( SSPC-SP6-63) or “Near White” metal finish. Prime same day.
b. Power Tool Clean
Follow instructions as outlined in SSPC-SP3-63 specification
c. Hand Cleaning
Follow instructions as outlined in SSPC-SP2-63 specification.
2. Galvanized Steel
a. New
Brush blast per SSPC-SP7.
b. Old, Weathered, or Rusty
Remove all oil, grease, dirt, and other foreign matter. Surface should be clean, dry and free
of contaminants. Remove all loose rust, etc., as outlined above under “steel”.
3. Previously Painted Surfaces
Remove all loose, peeling, or blistered paint, and any other surface contaminants. Make sure surface is sound and dry. Apply a test patch of PC-510 over the existing coating to insure compatibility.
4. Concrete
All new concrete must be cured at least 28 days. Do not use form release agents surface hardeners, or curing compounds.
PC-510 Page 3
Surface Preparation
All concrete should be prepared in accordance to the American Concrete Institute (ACI), Steel Structures Painting Council (SSPC), and National Association of Corrosion Engineers (NACE) concrete specifications. Remove all dirt, dust, oil, grease, laitance, efflorescence, loose or unsound concrete, and any chemical contaminants by such methods as high pressure water blast, wet or dry abrasive blast, vacuum shot blast, acid etching and other accepted surface preparation methods. A combination of these methods is normally used.
For on-grade concrete slabs check that a moisture vapor barrier film has been used. Testing may be necessary. Check for the presence of hardeners or residual forming membrane curing agents. Repair all cracks, spalled concrete, voids and expansion joints.
Coating System
The properly sound, cleaned concrete must be primed first with either PC-149, PC-155, or PC-1703 Epoxy Concrete Primer per label instruction.

MIXING INSTRUCTIONS
Stir each component to a uniform consistency, using a slow speed variable speed explosion proof drill with a Jiffy Mixer. Do not mix by hand. Make sure any pigment settled to the bottom is incorporated. Do not vary proportions. PC-510 is prepared by mixing 3 parts base (Part A) to 1 part Hardener (Part B) with a power mixer. PC-510 may be thinned up to 10% by volume for airless spray, and up to 20% by volume for conventional spray. When rolling, thin 10-20% by volume. PC-510 can also be applied by Plural Component Spray Equipment without solvent.
POT LIFE
The Pot life of PC-510 is approximately 40 minutes @ 75°F unthinned and 1-1/2 hours thinned.

3. Plural Component Equipment
When spraying, use a 50% overlapping crosshatch pattern to minimize the occurrence of pinholes. Do
notapply to surfaces below 45F or above 120F. Do not apply over dew or frost. The surface should
be dryand at least 5F above the dew point.

Times may be longer for thickness above 7 dry mils. For safety and proper product curing, good ventilation is necessary when painting indoors or in confined areas. Be sure the batch numbers are all the same to provide uniform color. Epoxy coatings may yellow or darken during application and after final cure. This will affect the color but will have no effect on the performance of the product. Heaters that emit carbon dioxide and carbon monoxide can cause the coating to yellow. For maximum interior gloss and color retention apply 1 topcoat of PC-270 Polyester Epoxy. For maximum exterior gloss and color retention apply a topcoat of CT-370 polyurethane.

CAUTIONS
PC-510 is combustible. Keep away from all sources of ignition during mixing, application and cure. PC-510 Hardener is corrosive. The Hardener and Base can cause eye and skin burns as well as allergic reactions. Use goggles, fresh air masks or NIOSH approved respirators, protective skin cream and protective clothing. This product is sold without warranty as to performance expressed or implied. Users are urged to make their own tests to determine the suitability for their particular conditions.
