Application Characteristics

Mix Ratio : N/A
Reducer: Apply at package viscosity for spray application. If some reduction is needed for easier spray application, reduce paint with a 4 to 1 volume blend of water to Glycol Ether EB in increments of 4% by volume.
Cleaning Solvent: Tap water is sufficient. A water/Glycol ether EB mix works better.
Pot Life: N/A

Force Cure : 120-140°F heat. with air movement speeds dry to handle to 1 hour.

Recommended Primers
Substrate

Recommended Primer

Aluminum/Galvanized Steel/Stainless Steel

Spot testing prior to production for adhesion of N-8584 should be performed to insure satisfactory results to these substrates. Please note that pre-treatment or use of a product such as a chromate wash primer may be required to achieve satisfactory results.

Ductile or Gray Iron Castings

N-8584 (surface profile should be considered when calculating the desired d.f.t.)

Plastics

Not designed as a primer for plastic.

Previously Painted Surfaces

Surface should be intact and sound. All loose and flaking material removed and bare spots primed with an appropriate primer. An area should be tested with the coating to assure compatibility.

Steel

N-8584 (surface profile should be considered when calculating the desired d.f.t.)

Wood

Not designed for priming wood.

Surface Preparation

Do not apply if the application surface temperature is below 45°F (7°C) or above 110°F (43°C), or if the surface temperature is within 5°F of the dew point. It is highly recommended that sound practices as set forth by SSPC or NACE be followed when preparing a substrate for painting. At a minimum the surface should be clean of all grease, dirt, oil, rust and foreign material that would be detrimental to proper adhesion and desired performance of the coating system being applied.
