NOTE:

1. Dry times due to the colder temperatures and higher DFT are extended significantly.
2. Primer is susceptible to amine blushing at lower temperatures and high humidity.
3. Primer can be recoated in a minimum of 16 hours at 35°F and 48 hours @ 20°F.
4. If you cannot recoat within 7 days, a light sanding with 220-320 grit open coat sandpaper must be done to assure proper topcoat adhesion.

Times will be longer for thickness above 2 mils DFT.  For maximum recoat times contact Gulf Coast Paint Mfg., Inc.   For safety and proper product curing, good ventilation is necessary when painting indoors or in confined areas.  Epoxy coatings may yellow or darken during application and after final cure.  PC-2.8 Hardener will darken with age.  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 primer to yellow.  PC-2.8 is designed as a primer; use appropriate topcoats.

MIXING AND APPLICATION INSTRUCTIONS

SURFACE PREPARATION

1. Steel

a. Sandblast (Recommended) 

Sandblast to a “commercial” (SSPC-SP6) or “Near White” (SSPC-SP10) blast finish. For best results, prime the same day with E-2.8 Epoxy Primer

b. Power Tool Clean

Follow instructions as outlined in SSPC-SP3 specification

c. Hand Cleaning 

Follow instructions as outlined in SSPC-SP2 specification

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 combability.

MIXING INSTRUCTIONS

Stir each component to a uniform consistency, using an explosion proof variable speed drill with an appropriate size Jiffy Mixer®.  Make sure any pigment settled to the bottom is incorporated.   DO NOT vary proportions.  PC-2.8 is prepared by mixing 2 parts Base (Part A) to 1 part Hardener (Part B) with a Jiffy Mixer® Power Mixer.  PC-2.8 may be thinned up to 15% with SA-65 Thinner.

When spraying, use a 50% overlapping crosshatch pattern to maximize hide and minimize the occurrence of pinholes.  Do not apply to surfaces below 35°F or above 120°F.  Do not apply over dew or frost.  The surface temperature should be at least 5°F above the dew point.  Manufacturers listed above are a guide.  Others may be used.  Changes in pressure and tip size may be required to achieve proper application.

CAUTIONS

E2.8 is Flammable.  Keep away from all sources of ignition during mixing, application and cure.  The Hardener (Part B) is corrosive and can cause eye and skin irritation as well as allergic reactions.  The use of goggles, fresh air masks or NIOSH approved respirators, protective skin cream and protective clothing is recommended standard practice when spraying coatings.  Proper ventilation is always required.
