For example, if a 4-lb weight falls from 12 inches, the impact energy is .
It is an excellent "torture test" for surface prep. If a metal substrate wasn't cleaned properly (oils or rust present), the coating will pop off during the reverse impact test, alerting the QC team to a process failure. astm-d2794
In the world of industrial coatings and paint manufacturing, a coating is only as good as its ability to stick to the substrate. You can have the most corrosion-resistant, chemically inert material in the world, but if it peels off the metal or plastic underneath, it has failed its primary purpose. For example, if a 4-lb weight falls from
If a new batch of paint passes impact testing at 80 in-lbs, but the next batch fails at 20 in-lbs, you have a formulation or mixing issue that needs to be addressed immediately. In the world of industrial coatings and paint
