SPARTAZERO^®

Test Method:
Paints are applied to black charts. After drying for seven days, the charts are placed in an abrasion testing machine and stopped at the indicated cycle. Complete deterioration occurs when a full line of black background is exposed.

Test Method:
A three mil draw down of the paint being tested is applied to the desired substrate (glossy aged alkyd, chalky latex, metal, etc.) and allowed to dry for 24 hours. After 24 hours, two 100 square sections are cut into the substrate using a Gardner Adhesion Knife. For dry adhesion test, Permacel tape is placed firmly over the cut with a 2" overlap of the test area. The tape is then quickly removed at a 180 degree angle. The amount of paint that is removed from the substrate is evaluated and scored using ASTM 0B – 5B rating (0 meaning complete paint removal from substrate and 5 meaning no paint removal). For wet adhesion, a 1" x 1" damp paper towel is placed over the cut section and allowed to rest there for ten minutes. After ten minutes, the paper towel is removed and the cut area is blotted dry of any excess moisture. Permacel tape is firmly placed over the test area with the same 2" overlap. The tape is then quickly removed at a 180 degree angle and the results are evaluated and scored (ASTM 0B – 5B). The lower the score, the poorer the adhesion is to that substrate. The same test method for wet/dry adhesion can be run again after a 3 day cure and 7 day cure to determine adhesion characteristic of the given paint.

Test Method:
Paints are applied to white charts and allowed to dry for 24 hours. The charts are then folded over each other. A weight is then placed on them to force the painted surfaces together. After 24 hours, the face-to-face charts are pulled apart to see if the dried paint stuck together.
