Use POR-15 Cleaner Degreased and POR-15 Metal Prep to properly get your surface ready for the POR-15 Rust Preventive Coating. Applications: Farm, industrial, marine commercial, and construction industries all use POR-15 Rust Preventive Coating to protect expensive and valuable equipment against rust, abrasion, and even graffiti.
Remove grease, oil, and other foreign substances using POR-15 water-based cleaner and prep products per the listed instructions. Stir POR-15 Rust Preventive Coating thoroughly, DO NOT SHAKE, then dispense a quantity of POR-15® Rust Preventive Coating into a separate container to avoid contamination.
POR-15 Rust Preventive Coating may be recoated or top coated when dry to the touch with a slight “finger drag”, typically 2 to 6 hours. Moisture will shorten the life of unused POR-15 Rust Preventive Coating.
POR-15 ® Rust Preventive Coating is easier and less expensive to apply than epoxies, since it doesn't require mixing: and POR-15 ® Rust Preventive Coating dries to a high-gloss or semi-gloss finish just like paint, except that it cannot be scratched or peeled off. Since POR-15 ® Rust Preventive Coating chemically bonds to metal, the underlying surface does not have to be sanded before application.
It dries to a rock-hard, non-porous finish that won't chip, crack, or peel, and it prevents rust from re-occurring by protecting metal from further exposure to moisture. POR-15 ® Rust Preventive Coating is cured and strengthened by exposure to moisture and will dry faster under extreme humidity, but moderate to dry atmospheric conditions are most desirable when applying this product, because extreme humidity may cause an immediate surface cure, trapping carbon dioxide gas below the surface.
Extreme humidity at the time of application may also interfere with proper adhesion of the POR-15 ® Rust Preventive Coating to metal because it's almost impossible to keep metal dry under such conditions. Its consistency is approximately that of paint and it has very good spread ability (one quart covers 96 square feet).
Surface must be dry and free of grease, oil, or other foreign substances. Refrigerate unused portion of POR-15 ® Rust Preventive Coating for longer shelf life.
TO TOPCOAT A FULLY CURED POR-15 SURFACE :Wet sand with 320 grit until gloss is dull, then paint, or use POR-15 ® Self Etch Primer directly on the cured POR-15 ® Rust Preventive Coating surface, then topcoat as desired. Use POR-15 ® Solvent or lacquer thinner for cleanup, which must be done before POR-15 ® Rust Preventive Coating dries.
NOTE: Organic vapor particulate respirators, Nosh/OSHA approved, must be used when spraying POR-15 ® Rust Preventive Coating. Moisture will shorten the life of unused POR-15 ® Rust Preventive Coating.
This process will leave a zinc phosphate coating on the metal and insure perfect adhesion. Use as a primer or finish coat Automobiles: fenders, floorboards, bumpers.
Trunk areas, engine compartments, rockers Trucks, trailers, agricultural equipment, snow removal and highway equipment Storage tanks, bridges, boats, factory machinery Outdoor sign supports, fencing, metal roofs, fire escapes Use to waterproof insulation or wood As a filler for metal Use as a bonding agent on wood or styrofoam Prevents rust in refrigeration units where moisture corrodes metal Use on lawnmower housing to prevent rust ; keep grass from sticking and clumping in wet weather. POR-15 ® Rust Preventive Coating SILVER contains metal filler and should be used on badly rusted steel to fill small holes and pitted areas.
POR-15 ® Rust Preventive Coating CLEAR dries to a perfect satin gloss, used on exterior surfaces before top coating. Better chemical resistance, better adhesion to metals, greater ease of application, strengthened by exposure to moisture.
POR-15 ® Rust Preventive Coating is sensitive to UV light (sun) and must be top coated for prolonged exposure to sunlight. POR-15 ® Rust Preventive Coating was tested for 168 hours at 97 °F in a condensing humidity salt spray (ATM B117).
At the end of the test period, coated steel was free of rust or pitting. The coating showed essentially no undercutting at the ascribed area after 2000 hours in a weatherometer *.
At the end of the test period, no undercutting was observed at the ascribed area. Laboratory tests have shown very good adhesion when applied up to 14 days after application of the first coat.
In an actual Field test, a topcoat was applied 6 weeks after the first coat had been applied, and the intercoat adhesion was excellent as determined by a crosshatch tape test. No visible rusting occurred at the welded areas after a six-month exposure.
The best part of this process is that it yields unusual and fascinating patterns and designs, and is very easy to do. Fabric placed in contact with this rusty surface quickly absorbs the color, and develops a permanent print that is almost impossible to remove.
Then spray a mix of equal parts of vinegar and water on the fabric at regular intervals to keep it moist and speed up the process. Oxidation soon sets in, and the fabric is imprinted with the pattern of the rust that develops on the objects.
The longer you leave the fabric in contact with the rust, the deeper the color becomes. Allow the fabric to stay in contact with the rust until you are satisfied with the pattern and intensity of color that it takes.
Once you’ve achieved the color you want, you can stop the rusting process by “neutralizing” the fabric. While the basic principle is leaving fabric in contact with a rusty surface, you can be as creative as you want with how to do this.
Different objects yield different patterns and the longer you leave it to rust, the more intense the color will be. For illustrations of both of the above techniques, check out this article taking us on a rust dyeing Adventure at the Textile Arts Center Blog.
Something Offset Warehouse’s resident fabric whiz, Jaime, has experimented with in the past (just take a look at the top image and the one below!). This means you can create intentional patterns rather than leaving it to chance with found items.
Printed and dyed fabrics usually take the stain better, as they do not contain anti-stain coatings that prevent the color from intensifying. With a little practice, you can perfect the technique and create more intricate patterns and designer works of art on fabric.
