DEVTHANE 349 - PART B - 3.79L (3:1)
Product Code: DC349C0910E-1GL
Description :
A high build, high performance, two-component chemically-cured polyaspartic aliphatic urethane gloss finish.
Intended uses :
For use on properly prepared steel, galvanized, aluminium and properly prepared concrete floors. Ideal for use on exterior or interior structural steel, piping, metal buildings, conveyors, pumps, storage tank exteriors, wind turbine towers, motors, machinery, and transportation vehicles.
Can also be used in the hard service areas of food processing plants, dairies, schools, restaurants, hospitals, correctional facilities, factories, stadiums, arenas, and amusement parks.
Advantages:
- Excellent gloss and colour retention
- Fast dry provides quick return to service
- Low VOC
- Easily applied by brush, roller or spray
- No film gassing
- Excellent resistance to marring, chipping, and scratching
- High build requires less coats
- May be applied direct to metal (refer to surface preparation requirements)
- Low temperature application (down to 2ºC (35°F))
- May be applied directly to organic and reinforced inorganic zinc rich primers
- Ready mixed colours contain no organic HAPS, and bases contain no organic HAPS before
tinting.
For use on properly prepared steel, galvanized, aluminium and properly prepared concrete floors.

hospitals, correctional facilities, factories, stadiums, arenas, and amusement parks.
Surface preparation
Surfaces must be dry, clean, free of oil, grease, form release agents, curing compounds, laitance, other
foreign matter and be structurally sound. Remove all loose paint, mortar spatter, mill scale, and rust.
New Surfaces
Steel:
Abrasive blast to minimum SSPC-SP6 or ISO8501-1:2007 Sa2½ commercial blast. The blast profile
should be jagged rather than “peened” and between 38-62 microns (1.5 to 2.5 mils). After blasting,
vacuum or blow off all abrasive dust and ensure surface remains clean before painting. Prime using:
Cathacoat 302H, Devran 223, Bar-Rust 231 or for a fast recoat system, use Devran 261QC
Please see Systems Compatibility section for approved primers. To ensure optimum appearance, any
primer or undercoat should be smooth and free of any surface defects such as runs, dry spray or heavy
orange peel.
Galvanized Steel and Aluminium
Remove dirt and oils by solvent cleaning or with Devprep 88 Cleaner or other suitable cleaner followed by
a thorough water rinsing. Prime using an approved primer. For direct to metal use, brush blast to a
standard similar to SSPC-SP-7 or ISO 8501-1:2007 Sa1 to create a surface profile. Prime using: Devran
201H, Devran 203 or Devran 205.
Concrete Floors, Poured Concrete:
Cure at least 30 days. Acid etch or abrasive blast slick, glazed concrete or concrete with laitance. Prime
with Bar-Rust 235 or Bar-Rust 231 epoxy primers or Devran 261QC epoxy primer for faster recoat.
Previously Painted Surfaces:
Poorly adhering old coatings should be removed. Wash to remove contaminants. Rinse thoroughly with
water and allow to dry. Dull glossy areas by light sanding. Remove all debris. Prime bare areas with
primer specified under New Surfaces.

Required tools
Airless spray
Recommended
Tip Range 0.38-0.48 mm (15-19 thou)
Total output fluid pressure at spray tip not less than
211 kg/cm² (3000 p.s.i.)
For airless spray application: Ideally, fluid hoses should not be less than 3/8" ID and not longer than
50 feet to obtain optimum results. Longer hose length may require an increase in pump capacity,
pressure, and/or thinning.
Air spray (conventional)
Recommended
For air spray application: Use a professional grade conventional gun with a 1.78mm (0.07") fluid tip
or larger. Adjust fluid and air pressure to achieve a good spray pattern.
Brush & roller
Suitable
Care should be taken that proper and uniform film thicknesses are obtained. Brushing and rolling
may require multiple coats to achieve correct film thickness and/or hiding.
How to use
Mixing
Material is supplied in two containers as a unit. Always mix a complete unit in
the proportions supplied. Once the unit has been mixed it must be used within
the working pot life specified.
(1) Agitate Base (Part A) with a power agitator.
(2) Combine entire contents of Curing Agent (Part B) with Base
(Part A) and mix thoroughly with power agitator.
Thinner : T-5 or T17
Thinning is not normally required. However, depending on local VOC and air quality regulations,
small amounts (5% or less) of T-5 Thinner may be added. Small amounts (5% or less) of T-17
Thinner may improve roller, brush or spray application. If local VOC and/or air quality regulations
are not an issue, and depending on the individual set-up of the spray equipment, additional thinning
may be allowed to obtain the desired individual finish especially at elevated surface temperatures.
Mix ratio
3 part(s) : 1 part(s) by volume
Working pot life
41°F (5°C) 59°F (15°C) 77°F (25°C)
105 minutes 80 minutes 1 heure
Drying time
Work stoppages
Do not allow material to remain in hoses, gun or spray equipment. Thoroughly
flush all equipment with T-5 Thinner. Once units of paint have been mixed they
should not be resealed and it is advised that after prolonged stoppages work
recommences with freshly mixed units.
Clean up
Clean all equipment immediately after use with T-5 or T-9 Thinners. It is good
working practice to periodically clean equipment during the course of the
working day. Frequency of cleaning will depend upon amount sprayed,
temperature and elapsed time, including any delays.
All surplus material and empty containers should be disposed of in accordance
with appropriate regional regulations/legislation.
Warning
* Devthane 349QC reacts with atmospheric moisture, and as such when in the can should remain
covered at all times. Failure to keep tin covered will result in skinning of paint and loss of pot life.
* Note: VOC values are typical and are provided for guidance purpose only. These may be subject
to variation depending on factors such as differences in colour and normal manufacturing
tolerances.
