POR-15® brings the powerful technology of polymeric isocyanate
derivatives to the consumer rust prevention market for the first time, a
technology vastly superior to competing products currently on the market.
POR-15 is easier and less expensive to apply than epoxies, since it doesn’t require mixing: and POR-15 dries to a high-gloss or semi-gloss finish like paint, except that it cannot he scratched or peeled off.

CHARACTERISTICS |
Since POR-15 chemically bonds to metal, the underlying
surface does not have to be sanded before application. As long as loose or
flaking rust are removed from the surface, an application of POR-15
will not only cover up the rust and prevent it from spreading, but will also
strengthen the underlying metal and seal holes by forming its own membranes.
GENERAL INFORMATION
POR 15 is a
paint-like substance which acts as a total rust inhibitor and also very
effective as a metal filler. Its consistency is approximately that of paint
and it has very good spreadability (one quart covers 96 square feet). POR
15 chemically bonds to rusted steel to form a rock-hard, nonporous coating
that won't crack, chip, or peel. It works by isolating metal from moisture;
without moisture present, steel can’t rust. Thin, covering coats are best.
Apply second coat when first coat is dry to touch with slight "finger-drag"
remaining.

APPLICATION OF POR-15 TO
NEW METAL
For proper adhesion to aluminum, galvanized metal, and smooth steel surfaces,
prep with POR-15 METAL-READY™ Rust Remover/PrePrimer. Keep
surface wet for 15 minutes, then rinse off with water and dry thoroughly. This
process will leave a zinc phosphate coating on the metal and insure perfect
adhesion.
ULTRA-VIOLET SENSITIVITY
POR-15 is sensitive to UV light (sun) and must be topcoated for
prolonged exposure to sunlight. Failure to do this may result in long-term
damage to the POR-15® coating. Topcoating is not required for areas not
exposed to sunlight.
WHICH FORMULA TO USE?
|
|
POR-15 SILVER contains metal filler and should be used on badly rusted steel to fill small holes and pitted areas. |
|
|
POR-15® BLACK is used on frames, floorboards. under fenders, engine compartments. trunk areas, etc. |
|
|
POR-15 CLEAR dries to a perfect satin gloss, used on exterior surfaces before painting. Excellent for "touch-up". |
|
|
POR-15 GRAY is ideal for use on concrete. |
Appearance:
Glossy or Semi-gloss (black only) finish.
Application: Brush, roller, spray
Spreadability: 96 sq. ft. per Quart, 384 so. ft. per gallon.
Recommended Temperature Application: 45°F - 95°F
Drying Time: Varies according to humidity; average is 4.5
hours.
Shelf Life: Unopened can - 2 years or more. Opened can - up to 6
months.
Abrasion Resistance: Using Taber Abrasion Test, POR-15®
passes 200 cycles with a 100 gram weight on a CF17 Wheel.
Solubility: POR-15 is readily soluble in esters. ketones,
and aromatic solvents.

Black is used when a high gloss finish is desired and semi gloss when a satin finish is called for. Please note that semi gloss black was not designed as a cosmetic finish and will therefore not always leave a uniform level of finish. Surfaces requiring a perfect semi gloss finish should be top coated with Chassis Coat Black. |
|
|
Gray is used in the industrial market, and also on concrete floors and walls for an indestructible finish far superior to existing specialty paints and products. |
|
|
Silver is the strongest of the colors because of it's metal content and is therefore recommended in cases of extreme corrosion where pinholes may have formed and therefore weakened the metal. It is also used to seal leaking fuel tanks, oil pans, and drums and is far stronger than a typical fiberglass repair when used with our Powermesh Reinforcing Fabric. POR-15 products do not contain styrene and may be safely applied over factory fiberglass. |
|
|
Clear can be used under body filler or where it is not desirable to loose light reflection such as below deck on a boat. The application of POR-15 Clear on wood will result in a 100% waterproof finish, which will offer far superior protection at a much lower cost and higher convenience when compared to marine plywood |
LABORATORY TEST RESULTS
POR-15 was tested for 168 hours
at 97°F in a condensing humidity salt spray (ASTM B117). At the end of the
test period, coated steel was free of rust or
pitting. Acid and alkali resistance test performed found panels coated with
POR-15 to be impervious to gasoline, oil, chromic acid, hydrochloric
acid, phosphoric acid, sodium hydroxide, caustic soda, 50% sulfuric acid,
and 50% hydrofluoric acid.
POR-15 was applied over a rusty substrate as a
finish coat (approximately 23 mils dry film thickness). The coating showed
essentially no undercutting at the scribed area after 2000 hours in a
weatherometer.*A 2 mil thickness of POR-15 was applied
to lightly rusted steel and then exposed for 1000 hours to a salt spray. At
the end of the test period, no undercutting was observed at the scribed
area. Recoatability is excellent. 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. A metal box used as a filter for raw sewage was coated
with POR-15 and placed in service within a few hours after the
interior and exterior were coated. No visible rusting occurred at the welded
areas after a six month exposure.
A POR-15 coating was subjected to 700°F for 10
hours; it remained hard and showed no apparent loss of adhesion. A panel
subjected to elongation was pulled beyond the yield point of the base metal
without affecting the POR-15 coating.
