Product Description
Corroseal™ is a water based copolymer latex rust converting primer. Corroseal™ when applied to rusted steel chemically converts the rust into magnetite, and primes the steel for a top coat of paint.

Recommended Uses
Corroseal™ is recommended for use on all steel surfaces as a rust converting paint primer; and as an etch primer or sealer on non ferrous metals such as copper, brass, bronze, and some aluminum.

Application Conditions
Corroseal™ may be applied when surface and air temperatures are between 40° F and rising, and 100° F and falling, 4° C and 38° C. Do not apply within 4 hours of expected rain. Wait until morning dew is off the surface before coating. Corroseal™ will tolerate some moisture. However, this does not include running, dripping, or sweating conditions. In enclosed compartments you must have two way air flow. Apply mechanical air movement of at least 10 to 20 atmosphere changes per hour. If tempera-ture is low add heat.

Application Instructions
1. Remove all millscale, flaking rust, and paint with power sanding tools, needle gun, descaler, wire brush, or water blast to SSPC SP2, SP 3, SP7 or SP12 WJ4. Always use a cleaner or solvent wipe to SSPC SP1 to remove oil, salt, and other chemicals. Always rinse off cleaner with fresh water. Acetone and ordinary dish washing detergents should not be used because they leave behind a residue of sulfonic acids or other unknown chemicals which interfere with primer adhesion. Cold rolled steel, abrade to anchor profile and degrease.

2. Do not thin! Brush or roll Corroseal™ from a plastic or stainless pan, using a synthetic bristle brush or short nap roller. Do not pattern or groove. Deep grooves from poor application will re-rust.

3. If spraying, use a 19 or 21 tip. Airless or Air powered both work. Do not over mist during application. With air unit, work about 10", 25 cm. from surface with 6"-8", 15 to 25 cm., fan. Airless work depends on the equipment. Do not allow work to run. Electrostatic works well with Corroseal™.

4. Apply 8-10 mils, 200 to 250 microns, wet coat, checking with wet film gauge. This will appear as a thick off-white film with no rust showing through. Corroseal™ turns from white to black with rust conversion. If Corroseal™ turns gray upon application, more Corroseal™ needs to be applied.

5. Second coat (if needed), should be applied when first coat is still tacky.

6. Drying time is generally related to air circulation, temperature, film thickness, and number of coats.

Paint Compatibility
Corroseal™ bonds well with enamel, urethane, epoxy, coal tar and most major topcoats. We recommend doing a test patch to ensure compatibility. Do not overthin topcoats as excess solvent creates cohesive failure. A stain blocker or an intermediate coat may be necessary when top coating with a light colored waterborne top coat.

Handling & Toxicity
Refer to MSDS sheet for complete details. Corroseal™contains no chemicals listed in EPA 40 CFR cp 1, Part 433. If swallowed, induce vomiting. Corroseal™ presents no significant vapor hazard but you should not breathe mist during spraying. Non flammable and non corrosive. Wear rubber gloves and protective glasses. In case of eye contact flush with plenty of water. Skin contact takes normal detergent and water. Follow all local, state and federal guidelines and laws for the safe handling of water-borne coatings. Dark stains clean up with 1:4 bleach to water. Normal clean up: detergent and water. Use no mineral spirits. Use lacquer thinner for equipment.

Do Not Use Corroseal With The Following
Zinc, Galvanized steel, Zinc Chromate, Zinc Phosphate, Strontium Chromate, Copper powder, Magnesium borate, Graphite, and Carbon black-this is a problem only in high concentrations such as conductive black primers. Do not use with any lead pigments or chromate pigments. These metals are not normally found in modern coatings. Do not use Corroseal™ on Food Preparation Lines where Corroseal™ is in direct contact with the food or beverage. It can be used when topcoated with an FDA approved topcoat. Check with the top coat supplier to see if an extraction test is required before proceeding. Always prepare a test patch to ensure compatibility with the substrate and follow on coatings.
