DESCRIPTION

CAL-551-001 Industrial Maintenance Coating for Metal, Concrete and similar Substrates

CAL551-001 is a versatile, elastomeric coating that can be used as a:

·          sealant for secondary containment and other concrete structures

·          crack-bridging concrete basecoat to protect less-flexible topcoats

·          topcoat on substrates subject to cracking, high vibration or other movement.

CAL551-001 contains particles of re-cycled rubber that have been surface-treated to cause them to cross-link into the coating system. This cross-linked rubber gives CAL551-001 excellent impact and long-term water resistance as well as UV stability.

CAL551-001 offers respectable chemical resistance and tolerates foot and light vehicular traffic. It has outstanding adhesion, can be applied to a wide variety of surfaces and tolerates less-than-ideal surface conditions.

In secondary containment applications, CAL551-001 can be applied to both asphalt and concrete structures. It has also been successfully applied to plywood floor surfaces.

SURFACE PREPARATION

Note: For optimal coating performance, take considerable care with surface preparation.

Metal: Remove all oil, grease or scale from the surface, then blast with sharp sand or grit to fin­ish. Use a non-spherical blast medium to give a 2 - 3 mil (50 - 75 micron) profile and to achieve the following surface preparation standards or their equivalents:

Non-chemical Service

Intermittent Splash or Wear

Immersion or Abrasive Service

SSPC-SP 6 Commercial Blast (NACE 3)

SSPC-SP 10 Near White Metal Blast (NACE 2)

SSPC-SP 5 White Metal Blast (NACE 1)

Concrete: Concrete should be aged at least 28 days before coating and the surface should be clean, dry and free of form-release agents, silicone water proofers and/or curing agents. Sand blasting or scarification is recommended. Wash down old con­crete to remove all residues and neutralize the pH before blasting or scari­fying.

These products are normally self-priming. However, under certain conditions such as old, porous or poorly finished concrete, CAL551-102 primer/sealer is recommended to avoid bubbling caused by outgassing. If these conditions exist, call Calicorp for assistance as two coats of CAL551-101 may be indicated on air entrained concrete.

MIXING PROCEDURES

Note:  Do not mix partial kits.

1.      Thoroughly mix the resin before adding the hardener. CAL551-001 is 100% solids and contains materials with high specific gravity.

2.      Empty the entire amount of hardener into the resin container.

3.      Mix thoroughly—until uniform in consistency—then continue to mix for an additional 2 - 3 minutes. Pay special attention to the bottom and sides of the container to insure complete mixing. Due to the high viscosity of this product, a mechanical mixer is preferred. Use at low speed and keep the mixing blade down in the product to avoid entrapping air. If mixing by hand, use a square-cornered, flat implement, such as a standard paint stirring stick.

THINNING

If thinning is necessary, especially at temperatures lower than 60° F (16° C), add 4 to 6 fl oz of MEK to the resin and mix thoroughly before adding the hardener. Note: Do not exceed 10% solvent by volume. Read the Material Safety Data Sheet for MEK (flammable liquid) before using it.

Do not keep the blended coating in the original container: exotherm – heat created during the curing process – can considerably shorten the pot life. Pour the coating into a rolling tray or large aluminum basting pan. Try to keep the depth of the coating in the tray below 3/8".

CAUTIONS

1.      If the ambient temperature is 85° F (29° C) or higher, pot life may be as short at 20 minutes. Have the working surfaces ready, and mix no more than one gallon of the coating at a time. To increase the pot life under these conditions, put the tray or pan on ice or in ice water. Do not get water or ice in the tray with the coating.

2.      The substrate temperature must be at least 5° F (3° C) above dew point—the temperature at which moisture will condense on the surface of the substrate—during all blast­ing and coating procedures. To calculate the dew point, consult the chart below.

Example: if the ambient air temperature is 70° F—top row below—and the relative humidity is 65%—left column—the dew point is 57° F. Under these conditions, the substrate temperature would need to be at least 62° F before proceeding with blasting and coating procedures.

APPLICATION

CAL551-001 may be sprayed, brushed, rolled or applied by squeegee. Use a medium bristle brush or a non-shed roller—3/8" nap or shorter—designed for use with epoxies. To spray CAL551-001, use an airless system—such as those available from Binks, DeVilbiss or Graco—with the following specifications a guideline:

MULTIPLE COATS

Second and subsequent coats must be applied before the previous coat has completely cross-linked. Apply additional coats when the previous coat will still string out (pigtail) and hold its shape when touched. If only slight tack remains, allow the product to cure, then brush blast before applying the next coat. Sanding or wire brushing may abrade small areas.

The same requirement applies when overlapping the seams of adjacent coating sections to create a continuous protective film. If the coating surface to be overlapped at the seam cannot be brush blasted, use a non-impact means such as power brushing or sanding to create a mechanical profile.

SPEED CURING

The cure time can be reduced and product performance enhanced by applying heat during the curing pro­cess of the final coat: 150° F (66° C) for 2 hours is recommended before placing the coating into full service.

CLEAN-UP

Use a mixture of MIBK and Xylene (50/50) or MEK for clean-up. Read the Material Safety Data Sheets for any of these products (flammable liquids) before using them. Skin can be cleaned with denatured alcohol, preferably ethanol.
