metal, concrete block, galvanized, aluminium, poured concrete and glazed brick. Ideal for use on
exterior or interior structural steel, piping, metal buildings, control cabinetry, conveyors, pumps,

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. 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.

New Surfaces:

Steel
Apply over surfaces which have been suitably prepared and primed. Consult the relevant primer datasheet for
advice on surface preparation requirements. Prime using: Bar-Rust 231, Bar-Rust 233H or Bar-Rust 235.

Galvanised Steel and Aluminium
Remove dirt, grease, oil or other surface contamination by solvent cleaning or with Devprep 88 cleaner or other
suitable cleaner, followed by a thorough water rinsing. Prime using: Devran 201H or Devran 203

Concrete Block

Remove loose aggregate and repair major voids. Fill with: Devran 220, Bar-Rust 231, Bar-Rust 235, Bar-Rust
233H thinned 25% with recommended thinner, or Tru-Glaze-WB 4015

Concrete Floors, Poured Concrete
Cure at least 30 days. pH must be 10.0 or lower before painting. Acid etch or abrasive blast slick, glazed
concrete or concrete with laitance. Prime using: Devran 220, Bar-Rust 231, Bar-Rust 233H, Bar-Rust 235, Tru-
Glaze-WB 4030 or Pre-Prime 167

Drywall:
Prime with a premium acrylic latex vapor barrier primer sealer.

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.

Fiberglass
Solvent wipe, scuff sand and solvent wipe again. Prime with Devran 201H epoxy.

Required tools
Airless spray
recommended
Tip Range 0.27-0.43 mm (11-17 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

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-9 ou T-17

Thinning is not normally required. However, depending on local VOC and air quality regulations,
small amounts (5% or less) of T-9 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.

Mix ratio
4 part(s) : 1 part(s) by volume

Working pot life
41°F (5°C) 59°F (15°C) 77°F (25°C)
6 hours 5 hours  4 hours 

Drying time



Cure Acceleration: Urethane catalyst 070A0000 may be used to accelerate cure at or below 5ºC
(40°F). The addition of one or two ounces per gallon will decrease the dry hard time approximately
one-third to one-half respectively at 40°F (5°C). The pot life will be reduced one-half to threefourths.

Work stoppages
Do not allow material to remain in hoses, gun or spray equipment. Thoroughly
flush all equipment with T-9 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-9 Thinner. It is good working
practice to periodically flush out spray 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
  • Maximum continuous dry temperature resistance for Devthane 379 is 121ºC (250°F). Exposure to continuous operating temperatures towards the maximum dry temperature resistance of this product may induce some discolouration, though the film will remain intact.
  • Devthane 379 reacts with atmospheric moisture, and as such when in the can should remain covered at all times. Failure to keep the tin covered will result in skinning of unused material and loss of pot life.
  • Devthane 379 may be tinted with industrial colourants; contact International Paint for further information. Add colourants only to the base portion and mix thoroughly before adding the converter portion.
  • 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.
