The STEEL IT High Solids,
Low VOC Epoxy System is a high-performance, two-coat barrier coating system that complies
fully with the latest environmental regulations while maintaining the same
high-performance profile and superior application characteristics associated with more
traditional STEEL IT compositions. Free of lead and chromium salt-based pigmentations, the
system has VOC levels substantially less than all current regulated thresholds. Both
the primer and the finish afford optimal physical properties that improve adhesion and
help the system withstand flexing and stretching. The cured film - pigmented with 316L
stainless steel flakes for enhanced performance - is highly durable and resistant to the
corrosive effects of oils, fats, spilled solvents, solvent fumes, alkalis and many dilute
organic and inorganic acids. The system is suitable for use on ferrous and nonferrous
substrates.
Engineered from the latest generation of low molecular weight epoxy, the system
consists of a "high solids, low VOC" barrier primer #4220 and a "high
solids, low VOC" stainless steel pigmented finish #4908. Available in a choice of two
gallon or two quart kits, both the primer and finish are user-friendly coatings with
excellent wetting characteristics and long pot life. They may be applied by a wide variety
of techniques, including brush, roller, conventional airspray, airless and air-assisted
airless applications.
| Protects Steel from: |
|
|
- Solvents and chemical spillage
|
- Moisture (fresh and salt)
|
- Mild acids, and mild and strong alkali
|
|
| System Requirements: |
- 1 Coat - STEEL IT High Solids Epoxy Primer #4220
- 1 or 2 Coats - STEEL IT High Solids Epoxy Finish #4908
|
| Surface Preparation: |
- General Use: Sandblast to an SSPC-SP-6 (commercial) or SSPC-SP-10 (near white) blast
quality.
- Immersion or Chemical Exposure: Sandblast to SSPC-SP-5 (white metal) blast quality.
|
| Film Thickness: |
- Atmospheric Service and Light Chemical Exposure: 3 dry mils of primer followed by 3 dry
mils of finish.
- Immersion and Heavy Duty Chemical Exposure: 5 dry mils of primer followed by two coats of
finish (4 dry mils each).
|
| Mixing: |
- Stir both components separately. Combine equal parts by volume and mix thoroughly. Allow
newly combined paints to stand for 15 minutes prior to use.
|
| Application: |
- Conventional Spray: Use Binks #95 gun with 66SS/66SK fluid tip/air cap or similar
equipment.
- Airless Application: Use a DeVilbiss JBG-501 gun with a fluid tip orifice between 0.015
and 0.021. Pump should be at least 28:1 or other compatible combinations.
|
| Dry Time: |
- #4220 Primer: Dry to touch in 3 hours. Allow to dry 12 hrs. between coats.
- #4908 Finish: Dry to touch in 4 hrs. Allow to dry 12 hrs. between coats. Cure continues
to advance for two weeks until full hardness and chemical resistance is achieved. Lower
temperatures delay curing time.
|
| Coverage: |
- Theoretical Epoxy Primer #4220: At 3 dry mils is 380 sq. ft./gal.
Theoretical Epoxy Finish #4908: At 3 dry mils is 365 sq. ft./gal. In
practice, their values will be reduced by at least 25% by loss factors.
|
| Thinning and Clean Up: |
- Thinning is not normally necessary. If required, up to 5% xylene or aromatic naphtha may be added to facilitate application without exceeding VOC thresholds. Do not
use any other thinners.
|
| Limitations: |
- Apply only when relative humidities are below 85%.
- Apply only when surface temperature is more than 5°F above dewpoint.
- Apply at temperatures above 50°F and less than 100°F.
- The maximum service temperature is 250°F.
