CorrosealApplication InstructionsSurface Preparation1. Remove all millscale, flaking rust, and paint with power sanding tools, needle gun, descaler, wire

brush, or water or abrasive blast to SSPC SP2, SP 3, SP7 or SP12 WJ4. Always use a cleaner or sol-

vent wipe to SSPC SP1 to remove oil, and other chemicals and Corroseal-Chlor-Ridto remove

chlorides. 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. On cold rolled steel, abrade to anchor profile and degrease.

2. Ensure surfaces are oil-free by visual examination. Check entire structure with water misted ontosurface. Any beading of water is indication of oil or grease contamination. Clean contaminated surfacin accordance with SSPC SP 1 and recheck for contamination until surfaces are grease and oil-fre. UseCorroseal-Chlor-RidTestkit to confirm surface is free of chlorides contamination.

Prepared surface shall have a neutral pH of 6-8 before CORROSEAL appliction.

Prepared surface shall be eye-visible dry. Do not apply to sweating steel.

Air and steel temperature shall be between 45F (7.2C) and rising or 100F(37.7C)& falling

Check dew point and temperature. Do not apply within 4 hours of expected rain fall. Wait unt morning dew is off the surface before coating.

Application3. Do not thin! Brush or roll Corroseal from a plastic or stainless pan, using a synthetic bristlebrush or short nap roller. Do not pattern or groove. Deep grooves from poor application will re-rust.

4. If spraying, use a 19 or 21 tip. Airless or Air powered both work. Do not over mist during applica

tion. With air unit, work about 10", 25 cm. from surface with 6"-8", 15 to 25 cm., fan. Airless workdepends on the equipment. Electrostatic works well with Corroseal.

Test compressed air system for oil contamination before using.

There shall be no runs, sags, streaks, flashes, laps, pinholing or cratering.

5. Apply 8-10 mils, 200 to 250 microns, wet coat, checking with wet film gauge. Theoretical

spread rate is 1 gallon per 200 sq. ft. 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 uponapplication, more Corroseal needs to be applied. See visual coating guide samples in this publicatio

There shall be no picking up or rolling up of the first coat during application of second pass.

Second coat (if needed) should be applied when first coat is still damp and tacky.

Do not pour un-used CORROSEAL from roller pan or air pot back into original

container to avoid contamination.

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

At 77F CORROSEAL should be dry to touch within 30 minutes. In enclosed compartments you must have two way air flow. Apply mechanical air movemen

of at least 10 to 12 atmosphere changes per hour. If temperature is low add heat.

Clean up with soapy water and rinse well. For hard dry splatter use lacquer thinner.

Topcoat ON STEEL DO NOT TOP COAT BEFORE 2 4 HOURSor re-rusting may occur. (24 h our cure is required by the chemical conversion process w ithin the rust .)The surface shall be free from any contamination prior to applying any topcoat.

Top Coat Recommendations

Acrylic Oil based coatings

Alkyd based enamels Polyurethane

Bituminous coatings Thermoplastic epoxy

Chlorinated rubber Urethane-asphalt

Epoxy/amines Urethane/coal tar

Epoxy/coal tar Urethane-water based

Epoxy/esters Vinyl

Epoxy/polymides Vinyl/tar

Latex

Note: If rust is not present the converter will not turn black and instead will dry clear.

This coating is very effective as etch-primer on aged tight paint. It may be used to cover, seal

and protect painted signs, logos, instructions, etc.

Do not overthin topcoats as excess solvent creates cohesive failure.

Some brands of waterbased viny/acrylic or light colored waterborne topcoats will react with the

tannic acid in Corroseal. Do a test patch of the topcoat over Corroseal and if brownish

stains appear use an oil-based stain blocker as an intermediate coat or use another type topcoat.

Corroseal primer chemistry is water based styrene butadiene copolymer.

Since it contains no pigment it eliminates the pin hole problems of other latex primers created

when latex traps air around pigment particles.

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 waterborne coatings. Dark

stains clean up with 1:4 bleach to water. Normal clean up: detergent and water. Use no mineral spirits.Use lacquer thinner to remove Corroseal from equipment.

Do Not Apply Corroseal Over The Following:

Galvanized steel Any Zinc present as pigment or as Galvanizing cancels the chemical reactioZinc necessary for Corroseal conversion to occur. Once Corroseal is applied

Zinc Chromate rusted steel, zinc coating may be applied over the Corroseal.

Zinc Phosphate

Strontium Chromate, Copper powder, Magnesium borate, Graphite, and Carbon black.

Carbon black 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 found in modern coatings.

Do not use Corroseal on Food Preparation Lines where Corroseal is in direct contact with the food orbeverage. It can be used when topcoated with an FDA approved topcoat. Check with the top coat supplie

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.
