 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. Spraying is the preferred method of application.
| 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.
- Anchor Pattern: Cut and angular, 2-3 mils deep. High
solids/high build systems demand deep anchor profiles for proper
adhesion.
|
| 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.
- Light service in 36 hours.
- 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. We offer our 6811 Epoxy Reducer for all STEEL-IT epoxies..
|
| 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.
