POR-15 Rust Preventive Paint Test ResultsWeather Resistance
|Weatherometer - The weatherometer is perhaps the most accurate weather resistance indicator due to the cycling of conditions. The cycle is 30 mins sun at 135 degrees F, 30% relative humidity and 30 mins dark at 75-80 degrees F, 100% relative humidity||1,000 hours of exposure equals 5 years of simulated exposure in the Rocky Mountain region. There was no change in 3 panels coated with POR-15 exposed for 2,000 hours.|
|ASTM B-117 Salt Spray - The oldest and most wildly used weather cabinet test. It introduces a spray in a closed chamber where specimens are exposed at specific locations and angles. It creates a 100% relative humidity condition in the exposure zone.|
Two separate B-117 tests. One with new steel and the other with rusted steel.
Estructural Strength Measures
|ASTM C-580 Flexural Strength - This test method measure flexural strength and modulus of elasticity expressed in pounds per square inch.||5,200 pounds per square inch|
|ASTM C-579 Compressive Strength - This test method measures compressive strength, the capacity of a material to withstand axially directed pushing forces.|
12,500 pounds per square inch - Verified. Not tested to failure.
ASTM C-307 Tensile Strength - This test measures tensile strength of cured chemical-resistant materials..
3,200 pounds per square inch
ASTM D-4541 Bond Strength To Concrete - This test method measures the strength of a coatings bond to concrete.
Concrete fails before POR-15. It far exceeds the tensile strength of concrete
|ASTM C-501 Taber Abraser - This industry standard for the establishment of an abrasive wear by determination of the loss of weight resulting from abrasion.|
In two separate ASTM C-501 Taber Abraser tests, POR-15 had:
|Chemical Bath Test|
After 200 hours of soaking in the following chemical bathes, panels coated with POR-15 experienced no changes: 10% hydrochloric acid, 50% sulphuric acid, 55% chromate, 85% phosphoric acid, 10% sodium hydroxide 98% methanol
|Raw Sewage Test||A metal box that houses a filter for raw sewage in a treatment facility was coated with POR-15. After a year of service no viable undercutting or rusting was present on the housing.|
Impact, Porosity and Temperature Tests
|Mil-D-3134J Impact Resistance||POR-15 exceeds standards in paragraph 3.15|
|ASTM C-413 Water Absorption - This test method covers the determination of the absorption of chemical-resistant mortars, grouts, monolithic surfacings, and polymer concretes.||0.0001 maximum|
|NACE Stand TM0174||0.00 POR-15 is a non-porous coating|
POR-15 is temperature resistant up to 450 degrees. A test showed that no adhesion was lost at 450 degrees F for 10 hours
