Hi guys ; POR-15 is truly a great product with many uses other than surface protection. The following is some information about the product.
Por-15 paint is moistured cured. That said, it doesn't mean you can paint over a water soaked surface and have it stick.
Facts about POR-15.
surface MUST be free of oil and grease and dry to the touch.
solids- 74%,
tested at 700 degrees F, no loss of adhesion, or hardness after 10 hrs
pigment used in black is pure carbon, in silver it is aluminum
it is UV sensitive
covers 96 sq.ft. single coat, 2 coats are recomended
it is impervious to gasoline, oil, chromic acid, hydrochloric acid, phosphoric acid, sodium hydroxide, caustic soda, 50% sulfuric and hydrofluoric acids.
DO NOT SPRAY WITHOUT USING ORGANIC VAPOR RESPORATOR OR FRESH AIR SUPPLIED HOOD. Contains polymeric isocyanate derivatives. It is too expensive spray even with HVLP equipment. It is self leveling. A bristle or foam brush will leave a streak free finish.
DO NOT SHAKE THE CAN, stir gently ( like a martini ) Very little stirring is required as pigment stays in suspension really well.
If you sand blast POR with Black Beauty it will bounce off it. Eventually you can wear a hole through it, but you will not be able to get under it and chip off the paint.
Preservation of opened can: 1 drop of water will ruin a whole can of paint. Short term storage---Clean groove really good and put plastic wrap between can and lid. Turn can upside down and store in refrigerator. By inverting the can, if the paint does skim over the skim will be on the bottom when you go to use it. Use as soon as possible.
Long term storage: Transfer unused paint into a smaller container. You are trying to reduce the air space on top of the paint as much as possible. Then follow short term storage.
