POR-15 Rust Preventive Paint Test Results
Weather 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 |
Abrasion Resistance
| 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 Resistance
| 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 |
| Temperature Resistance | POR-15 is temperature resistant up to 450 degrees. A test showed that no adhesion was lost at 450 degrees F for 10 hours |
