POR-15 POR PATCH APPLICATION INSTRUCTIONS
PorPatch is a thick, pudding-like substance which acts as a total rust
inhibitor and is also very effective as a metal filler. PorPatch can be easily
brushed, or troweled. It chemically bonds to rusted steel to form a rockhard,non-porous coating that won’t crack, chip, or peel. Because it is actually
POR-15 in a thickened state, it works by isolating metal from moisture;
without moisture present, steel can’t rust..
PorPatch is easier and less
expensive to apply than epoxies because it doesn’t require mixing. Since
PorPatch actually bonds chemically to metal, the underlying surface does
not have to be sanded before application. As long as loose or flaking rust
is removed from the surface, an application of PorPatch will not only cover
up the rust and prevent it from spreading, but will strengthen the underlying
metal and seal holes by forming its own membranes..
PorPatch is a highly concentrated version of world famous POR-15 Rust
Preventive Paint. Through new blending technology, we have added solids,
reduced the solvent carrier, and homogenized the resulting blend into a
thick, workable paste which can be troweled from a can or squeezed from a
tube. A cured mass of PorPatch is virtually indestructible, yet it will remain
flexible and won’t crack or chip. Because it’s non-porous..
PorPatch can
totally seal seams like no other product, and like regular POR-15, it can be
applied directly to rusted surfaces.
PORPATCH is the ultimate filler. It hardens like steel, but won’t chip or
crack. It has the consistency of chocolate pudding and can be used to
repair concrete and cinderblock. It will fill holes in steel, wood, plastic; it
is waterproof and non-porous.
As a moisture barrier, PorPatch is unsurpassed,
and its bonding characteristics to cured concrete far exceed those
of cement and other patching compounds. It will not crack or fracture even
when pounded on with the heaviest mallet! PorPatch is also a heavy-duty
adhesive and can be used to bond plastic to steel or concrete or wood..
Use PorPatch to repair broken, cracked concrete, cement walkways; dock
maintenance: make waterproof patches to repair pre-formed concrete
where moisture has penetrated through cement patches and caused rusting
of rebar and expansion through freezing; waterproof concrete tanks,
repair joints where railings have loosened from their concrete base..
PorPatch is impervious to all fuels and can be used for exterior repairs to
fuel tanks along with standard fuel tank repair. PorPatch dries to the touch
in about 4 hours, but full cure may take 96 hours(4 days) or more, depending
on the thickness applied..

APPLICATION OF POR-15 TO NEW METAL
For proper adhesion to aluminum, galvanized metal, and smooth steel
surfaces, prep first 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..

LABORATORY TEST RESULTS
PorPatch was tested for 168 hours at 97oF(36oC) 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 PorPatch
to be impervious to gasoline, oil, chromic acid, hydrochloric acid,phosphoric acid, sodium hydroxide, caustic soda, 50% sulfuric acid, 50%
hydrofluoric acid..
PorPatch was applied over a rusty substrate as a finish coat (approximately
2-3 mils (50-75um) dry film thickness). The coating showed essentially
no undercutting at the scribed area after 2000 hours in a weatherometer*.
A 2 mil (50um) thickness of PORPATCH 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 hours after application of the first coat. In an
actual field test, a topcoat was applied 2 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 PORPATCH
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 PORPATCH coating was subjected to 500oF(260oC) 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 PORPATCH coating..
*WEATHEROMETER - Dew cycle XWR with corex D fi lter, cycle is:
1. 30 minutes sun, 135oF (57oC), 30% relative humidity.
2. 30 minutes dark, 75-80oF (23-26oC), 100% relative humidity
(achieved with water spray on panel backs) ..
TYPICAL APPLICATIONS
Use as a primer or finish coat..
Automobiles: fenders, floorboards, bumpers, trunk areas, engine compartments, rockers..
Trucks, trailers, storage tanks, agricultural equipment, snow removal and
highway equipment, factory machinery, bridges, boats, all types of marine use.
Outdoor sign supports, fencing, metal roofs, fire escapes.
Use to waterproof insulation or wood.
Use as a filler for metal.
Use as a bonding agent on wood or styrofoam. Prevents rust in refrigeration
units where moisture corrodes metal..
ADVANTAGES OF PORPATCH OVER MOST DUAL-COMPONENT
COATINGS OR SEALERS
Better chemical resistance, better adhesion to metals, greater ease of
application, strengthened by exposure to moisture. Reasonable pot life,
non-shattering, great fl exibility. No catalyst required for curing..
