E275 High Build Polyamide Epoxy Mastic | Chemical Resistant | Excellent Adhesion to Steel

RECOAT TIME

Times may be longer for thickness above 5 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 coat of E270 Polyester Epoxy.  For maximum exterior gloss and color retention apply a top coat of E370 or E398 polyurethane.

SURFACE PREPARATION

Remove all dirt, grease, oil, soil, chemical contaminants, and other matter before any mechanical preparation.  The surface must be free of any salt contamination.  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

Sand Blast – Best

Sand Blast to a “Commercial” (SSPC-SP6) or “Near White” (SSPC-SP10) metal finish.

Power Tool Clean

Follow instructions as outlined in SSPC-SP3 specification.

Hand Cleaning

Follow instructions as outlined in SSPC-SP2 specification.

Note:  Prime the same day.

2. Galvanized Steel/Aluminum: Solvent clean per SSPC-SP1 or steam clean.  Sweep blast to achieve a

minimum 1 mil profile.

3. Previously Painted Surfaces: Solvent clean per SSPC-SP1 and/or power wash.  Remove loose existing

paint by wire brush or other hand tools.  Feather edges.  Make test application to check for compatibility.

4. Concrete

In all cases of surface preparation, the pH should be checked.  A pH reading of 7.0 to 8.5 is acceptable.  Also, a Water Dissipation Test should be made on random areas of the floor to determine if the proper degree of porosity has been achieved.  Before the installation of any Gulf Coat Paint Products, the substrate should be examined for moisture.  Test for moisture vapor transmission using ASTM F-1869 Standard Test Method for Measuring Moisture Vapor Emission Rate of Concrete Subfloor using Anhydrous Calcium Chloride.  The maximum allowable rate is 3 lbs. per 1,000 square feet per 24 hours.  Test for relative humidity in concrete floor slabs using Probes according to ASTM F-2170.  This test measures the presence relative humidity of the slab below the surface.  The maximum relative humidity should be below 80%.

New concrete must be cured at least a minimum of 28 days before applying a coating.  On-grade slabs must have moisture vapor barrier in place.  All laitance, sealers, efflorescence, chemical contaminants, grease, oil and other foreign material must be removed.  The prepared surface must be clean, dry and structurally sound.  We recommend mechanical preparation by means of shot blasting or diamond grinding to achieve a CSP-2 or CSP-3 profile, in accordance with the International Concrete Re- pair Institute (ICRI).  The profile should reflect something similar to a 60-100 grit sandpaper.  If the substrate is not properly prepared and the appropriate profile is not achieved, failure of the product to adhere to the substrate may occur.

Old concrete surfaces must be structurally sound.  Any unsound areas must be repaired prior to proceeding with the resinous installation.  For proper patching and repairing, use E615 and/or E1000 with graded aggregate.  Remove existing paint and loose concrete by rough sanding, sandblasting, high pressure water cleaning, shot blasting or grinding.  In some cases where plant conditions allow, a stripper maybe used to remove excessive build-up of paints or sealers.

Coating System 

The properly sound, cleaned concrete should be primed first with either E149, E155 or E1703 Epoxy Concrete Primer per label instruction. Two coats of E275 Polyamide Epoxy at approximately 5-8 mils dry per coat is recommended for light traffic areas. For heavy forklift and high abrasion areas, E352 Polyester Polyurethane Coating at 2-3 mils dry film thickness is recommended as the top coat over the E275 Polyamide Epoxy.

MIXING INSTRUCTIONS 

Stir each component to a uniform consistency, using a slow speed variable speed drill with a Jiffy Mixer. Do not mix by hand. Make sure any pigment settled to the bottom is incorporated. Do not vary proportions. E275 Polyamide Epoxy is prepared by mixing 1 part base (Part A) to 1 part Hardener (Part B) with a power mixer. E275 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 Allow 15 minutes induction time.

Roller – Use a 3/8” – ½” nap, phenolic core, shed resistant roller cover.  Roll in the same direction always keeping a wet edge.  Do not over roll product.

Brush – Use pure bristle brush.

When spraying, use a 50% overlapping crosshatch pattern to minimize the occurrence of pinholes.  Do not apply to surfaces below 50°F or above 120°F.  Do not apply over dew or frost.  The surface should be dry and at least 5°F above the dew point.

CAUTIONS

E275 is flammable.  Keep away from all sources of ignition during mixing, application and cure.  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.
