The reactivity of a thermoset coating powder is evaluated by gel time and inclined plate flow.; How well the coating powder stands up under storage conditions can be inferred using a simple test called blocking or sintering.Blocking is usually is a challenge with . A common test to determine the abrasion resistance of a coating is the Taber test. To perform the Taber test, the coating material being evaluated is applied to a solid, flat plate. After the coating has cured, the plate is then loaded into the test machine. Abrasive wheels are placed onto the coating and are moved around on the plate's surface .
Impact Resistance Test Impact tests signify toughness, or impact strength, of a coating to absorb energy under mechanical load. The drop impact test (or falling-weight impact test) is a commonly used test method to determine the impact resistance. The test standards used for impact resistance testing include:

The thickness of the coating can have a big impact on its efficacy, both during application and over time. Nano-impact test on PVD coatings is an efficient method for investigating film failure mechanisms. During this test, the coating is subjected to repetitive impacts by a diamond indenter, inducing high local deformations and stresses into the film material, which may lead to .
Adhesion is also a measurable result of some hardness tests made by pencil hardness, gravelometer, impact (falling dart, etc.) or mandrel bend. Coating chip-off should be recorded during these tests. Finally, loss of adhesion can be noted during some chemical resistance tests where the coating blisters, bubbles up or even falls off.Impact Resistance (ASTM D2794) measures the resistance of organic coatings to the effects of rapid deformation (Impact). Impact resistance is measured by placing a coated panel in an universal impact tester. A standard weight is dropped a distance to strike an indenter that deforms the coating and the substrate. The
