Warning: The above table provides general guidelines only. Always consult your ICI Paints’ Representative for appropriate recoat windows since the maximum aged recoat time of this product may be significantly shortened or lengthened by a variety of conditions, including, but not limited to humidity, surface temperature, and the use of additives or thinners. The use of accelerators or force curing may shorten the aged recoat of individual coatings. The above recoat windows may not apply if recoating with a product other than those listed above. If the maximum aged recoat window is exceeded, please consult your ICI Paints’ Representative for appropriate recommendations to enhance adhesion. Failure to observe these precautions may result in intercoat delamination.

Shelf Life: Over 24 months at 77°F (25°C) – unopened Mix Ratio By Volume:4(base):1(converter)–see mixing instructions.

Induction: None Pot Life: 4.5 hours @ 77°F (25°C) & 50% R.H.

Advantages:

Limitations of Use: Exterior exposure will cause a color change, early dulling, and loss of gloss, but this does not affect protective properties. Epoxy coatings may yellow during application and cure if exposed to the combustion by-products of improperly vented fossil fuel burning heaters. Commonly finished with DEVTHANE® Urethane Enamel for maximum exterior color & gloss retention. Do not use for fuel or solvent immersion.

GENERAL SURFACE PREPARATION

DIRECTIONS FOR USE

PRECAUTIONS

SHIPPING

Tinting: Tint the appropriate base with CHROMA-CHEM* 844 colorants. (Do not use water based or other colorants.) Add colorants to only the base portion.

Mix thoroughly before adding the converter portion.

Thinning: Thinning is not normally required or desired; however, at extreme environmental conditions, small amounts (15% or less by volume) of T-10 thinner can be added depending on local VOC and air quality regulations. When using BAR-RUST 235 epoxy over aged alkyds, use T-5 thinner. Any solvent addition should be made after the two components are thoroughly mixed.

Mixing: BAR-RUST 235 epoxy is a two component product supplied in 5 gallon and 1 gallon kits that contain the proper ratio of ingredients. The entire contents of each container must be mixed together. Power mix both portions first to obtain a smooth, homogeneous condition. Then add the converter slowly with continued agitation. After the converter add is complete, continue to mix slowly.

Avoid storing or placing containers in direct sunlight.

Application: Spray is preferred for appearance and film build control. For air spray application, use a fluid tip of .070'' or larger, a professional grade conventional gun and an air cap with good break-up. The fluid pressure should

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. All direct to metal coatings provide maximum performance over near white metal blasted surfaces. There are situations and cost limitations which preclude blasting. BAR-RUST® 235 epoxy was designed to provide excellent protection over less than ideal surface prepara-tion. The minimum standard for non-immersion service is SSPC-SP2 or ISO-St2;

for immersion service the minimum standard is SSPC-SP3 or ISO-St3. These minimum surface preparation standards apply to steel that has been previously abrasive blasted, coated and deteriorated. Where very rusty surfaces still remain after cleaning use PRE-PRIME™ 167 Sealer before application of BAR-RUST® 235 epoxy. All direct to metal coatings provide maximum performance over near-white blasted surfaces.

New Surfaces: Steel – Blast to near-white metal surface cleanliness in accordance with SSPC-SP10 or ISO-Sa 2-1/2 for immersion service, or commercial blast cleanliness in accordance with SSPC-SP6 or ISO-Sa2 for non-immersion service.

Blast profile on steel should be 1.5 to 2.5 mils (38-62 microns) in depth and be of a sharp, jagged nature as opposed to a “peen” pattern (from shot blasting).

Surfaces must be free of grit dust. Concrete Block – Remove loose aggregate and repair voids. Fill with this product, TRU-GLAZE® 4010 or TRU-GLAZE-WB™ 4015 blockfillers. Concrete Floors, Poured Concrete – Cure at least 30 days. Acid etch or abrasive blast slick, glazed concrete or concrete with laitance. Prime with PRE- PRIME 167 sealer or this coating. Galvanized Steel – Remove dirt and oils by solvent cleaning or with DEVPREP® 88 Cleaner or other suitable cleaner followed by a thorough water rinsing. Prime with DEVRAN® 203 or DEVRAN 205 epoxy primers for non-immersion. For immersion or severe moisture condition, abrasive blasting is recommended before priming with this product or DEVRAN 201 epoxy primer. Previously Painted Surfaces: Old coatings should be tested for lifting. If lifting occurs, remove the lifted coating. Otherwise scuff sand glossy areas and aged epoxy coatings. Clean aged epoxy or urethane coatings with DEVPREP 88 Cleaner. Remove cracked and peeling paint. Prime bare areas with primer specified under New Surfaces. If thinning is required, thin with T-5 thinner only when used over aged alkyd coatings. Use only products that are in compliance with local VOC regulations.

DANGER! COMBUSTIBLE LIQUID AND VAPOR. CAUSES EYE AND SKIN BURNS. HARMFUL OR FATAL IF SWALLOWED. ASPIRATION HAZARD - CAN ENTER LUNGS AND CAUSE DAMAGE. HARMFUL IF INHALED. MAY CAUSE CENTRAL NERVOUS SYSTEM EFFECTS, INCLUDING DIZZINESS, HEADACHE OR NAUSEA.

CAUSES RESPIRATORY TRACT IRRITATION. MAY CAUSE ALLERGIC SKIN AND RESPIRATORY REACTION. MAY BE HARMFUL IF ABSORBED THROUGH SKIN.

OVEREXPOSURE MAY CAUSE BLOOD, LIVER, KIDNEY DAMAGE. CONTAINS CRYSTALLINE SILICA WHICH CAN CAUSE LUNG CANCER AND OTHER LUNG DAMAGE IF INHALED. CONTAINS MICA WHICH MAY CAUSE PNEUMOCONIOSIS. USE ONLY WITH ADEQUATE VENTILATION. KEEP OUT OF THE REACH OF CHILDREN.

NOTICE: Products in this series contain solvents. Reports have associated repeated and prolonged occupational overexposure to solvents with permanent brain and nervous system damage. Intentional misuse by deliberately concentrating and inhaling the contents may be harmful or fatal. For emergency information call (800) 545-2643. Note: These warnings encompass the product series. Prior to use, read and follow product specific MSDS and label information. Keep away from heat, sparks and flame. Do not smoke. Vapors may ignite. Extinguish all flames, burners, stoves, heaters and pilot lights and disconnect all electrical motors and appliances before use and until all vapors are gone. Prevent build-up of vapors by opening all windows and doors to achieve cross-ventilation. If sanding is done, wear a dust mask to avoid breathing of sanding dust. Do not breathe vapors or spray mist. Ensure fresh air entry during application and drying. Avoid contact with eyes and skin. If you experience eye watering, headaches, or dizziness, leave the area. If properly used, a respirator may offer additional protection. Obtain professional advice before using. Close container after each use. FIRST AID: In case of skin contact, wash thoroughly with soap and water. If any product remains, gently rub petroleum jelly, vegetable or mineral/baby oil onto skin, then wash again with soap and water. Repeated applications may be needed. Remove contaminated clothing. For eye contact, flush immediately with large amounts of water, for at least 15 minutes. Obtain emergency medical treatment. If swallowed, obtain medical treatment immediately. If inhalation causes physical discomfort, remove to fresh air. If discomfort persists or any breathing difficulty occurs, get medical help. KEEP FROM FREEZING. DS238-1003 be kept low, with just enough air pressure to get good break-up of the coating.

Excessive air pressure can cause over-spray problems. Where airless equip-ment is used, an airless spray pump capable of 3,000 psi (207 bars) and .019” to .025” tip size will provide a good spray pattern. 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. BAR-RUST 235 epoxy may also be applied by brush or roller. Care should be taken that proper and uniform thicknesses are obtained. For roller work use a clean synthetic roller with 1/4”-1/2” nap. New rollers should be thoroughly wet with the specified thinner and spun vigorously to remove loose fibers. Brushing and rolling may require multiple coats to achieve correct film thickness and/or hiding.

Spreading Rate: Apply at 130-250 ft2/ gal. (3-6m2/L) depending on surface texture and porosity. Make allowance for any losses due to over-spray or surface irregularities.

Clean-up: Use T-10 Thinner or other appropriate thinner in compliance with local VOC regulations.
