ACRI-HUES^®

Good adhesion means the paint sticks to the substrate allowing for better protection of the painted surface. ACRI-HUES^® does a better job at sticking to the surface, as the National Brands are more prone to peeling, when exposed to moisture.

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.

When exterior paints are subjected to heat from the sun, they can become soft and tacky, allowing dirt to stick to the film.

Test Method:
Paint is applied to aluminum panels and allowed to dry at room temperature for seven days. A layer of black iron oxide slurry is applied to the bottom half of the panel and allowed to dry at room temperature for two hours. To accelerate testing, the panels are placed in an oven at 120° F for two hours to further dry the slurry on the paint film. The panels are cooled and washed under cold tap water. The amount of slurry that remains on the panel is the dirt pick-up.

When two painted surfaces come into contact, such as a door and door jamb, they can stick together, or block. When that happens, the paint can peel from the surface. ACRI-HUES^® clearly beats the National Brand, as their paint is sticking together and peeling from the surface.

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.
