FX-408

FX-408 was used in the following case studies:

DESCRIPTION:

FX-408 Epoxy Organic Zinc Rich Primer is a two component epoxy primer which provides both barrier and sacrificial protection against steel corrosion. FX-408 promotes adhesion, dries rapidly, and can be either shop or field applied. Meets SSPC Paint Specification No. 20, Type II.

ADVANTAGES:

Has excellent corrosion resistance; affords galvanic protection to adjacent undercoated areas
Can be shop- or field-applied primer for steel
Can be welded in thin (1/2 to 1 mil) films
Provides superior abrasion resistance
Salt resistant
May be used as a weldable, pre-construction primer

PHYSICAL PROPERTIES:

Color	Gray
Finish	Flat
Tack Free Time	1 hr max @ 72°F
Pot Life	6 hours min @ 72°F
Solids By Weight	88%
Solids By Volume	58%
Percent of Zinc in dry film	90%
VOC	2.95 lbs/gallon
Viscosity	100 Krebs units
Dry Temperature Resistance Untopcoated	Continuous 300°F Non-continuous 400°F

SURFACE PREPARATION:

Steel Surfaces: Prior to abrasive blasting insure all surfaces are clean, dry and contaminant free. Steel surfaces shall be abrasive blasted to a minimum SSPC SP-6 Commercial Blast. Surface profile should be 1.0 to 2.5 mils. All blasted steel shall be coated the same day with FX-408 Zinc Rich Primer.

MIXING:

Power mix Component "A" thoroughly before combining with Component "B". Combine 5 parts by volume Component "A" to 1 part by volume Component "B". Mix for not less than three (3) minutes, using slow speed drill (300 to 600 rpm) and FX-Mixing Paddle.

Please note FX-408 will not cure without the use of Component "B". When mixing is completed cover and protect material and allow to induct for a minimum of 45 minutes prior to application. Re-agitate material prior to application.

APPLICATION:

FX-408 Epoxy may be applied by brush, conventional spray or airless spray. Stir intermittently during application to prevent zinc settlement. All spray equipment must employ traps to prevent water and oil from contaminating coating.
The following spay equipment has been found suitable; Graco, DeVilbiss, and Binks. Keep material under mild agitation during application. If spraying is delayed, re-circulate the remaining material in spray line. If spraying or work is stopped do not leave material in spray lines longer than 10 minutes.

Conventional Spray:
Agitated pressure pot equipped with dual regulators, 3/8” I. D. minimum material hose, with a maximum length of 75", 0.070 fluid tip and appropriate air cap.

Airless Spray:

Pump ratio	30:1
Gallons per minute output	3.0 min
Material hose	3/8" I.D. min
Tip size	0.019 to 0.025
Output psi	2100 to 2500
Filter size	60 mesh
Teflon packings are recommended

Brush:
For touch up of areas less than 2 sq ft only use medium bristle brush and avoid over brushing.

Roller:
Not recommended

Dry Film Thickness:
Recommended dry film thickness is 2.0 to 4.0 mils DFT. Applications in excess of 5.0 mils DFT per coat are not recommended.

When used as a weldable, pre-construction primer the recommended DFT is 0.5 mils to 1.5 mils DFT over the abrasive blasted profile. Please contact a Fox Industries Technical Representative for thinning instruction if used as a weldable primer.

APPLICATION CONDITIONS:

Minimum ambient temperature shall not be below 40°F. Maximum temperature shall not exceed 100°F.
Minumum substrate temperature shall not be below 35°F. Maximum substrate temperature shall not exceed 120°F.

CURE SCHEDULE:

These times are based on a 3.0 mil DFT with 50% relative humidity.

Dry time to handle	8 hrs @ 40°F
Dry time to recoat	24 hrs @ 40°F
Dry time to handle	1 hr @ 75°F
Dry time to recoat	12 hrs @ 75°F

Force curing is acceptable. Please consult Fox Industries Representative for cure schedule information.

COVERAGE:

Theoretical coverage rate of FX-408 is as follows:

450 sq ft/gal	2.0 mils DFT
300 sq ft/gal	3.0 mils DFT
230 sq ft/gal	4.0 mils DFT

CLEAN UP:

Use xylene or FX-Epoxy Cleaner. In case of spills, absorb and dispose of in accordance with applicable guidelines.

SHELF LIFE:

2 years

STORAGE:

Store materials in a protected indoor area. Storage temperature shall be between 50°F to 85°F.

PACKAGING:

One (1) gallon kit - 1 gallon Component "A" and 1 quart Component "B".

CAUTION:

DANGER! FLAMMABLE! Contains xylene. Keep away from heat, sparks, and flame. Avoid breathing vapor. Use with forced air ventilation in confined areas. Avoid contact of resin or hardener with skin or eyes. In case of eye contact, flush immediately with plenty of water and consult a physician. Do not take internally.
