In industries where strength and performance are critical factors, durability is the key point, and paint and coating that can resist physical forces would be the most needed in such industries. A direct way to test this resistance is through impact resistance tests, which mimic real-world exposures to paints and coatings to force changes and identify weaknesses. Manufacturers can avoid costly defects, improve product quality, and meet industry standards by identifying issues early.
What is Impact Resistance Testing?
Impactors are also a method that is applied in determining resistance to impacts by the effect of how a painted surface bears physical stresses and forces such that there are no indicators of damages, including cracking, chipping, and peelings. The test reflects normal situations when coatings are susceptible to impacts or shocks, typically when slamming the car's door open, or if packaged items are being held and carried around.
Testing Method
Impact resistance testers apply controlled forces to the painted surface, and these come in the form of either falling weight or pendulum impact testers. These enable producers to measure the capacity of any coating to resist direct forces from a sharp object, as well as blunt pressures. Testing is done on an established weight dropped or swung onto the painted surface whereby the amount of damage sustained, or otherwise, will be observed and recorded.
Standards
Impact resistance testing follows industry standards such as ASTM D2794 and ISO 6272. These standards give precise methodologies for measuring the impact resistance of a coating, indicating how durable its coating would be under different impacts.

Common Paint Issues Identified Through Impact Resistance Testing
1. Chipping
Chipping occurs when small paint fragments chip off after some impact, usually due to poor adhesion or a thick coat, allowing moisture and corrosion to penetrate the surface.
2. Peeling or Delamination
When the paint peels, it has separated itself from the surface due to some poor adhesion and insufficient curing process.
3. Cracking
Cracking happens when the paint, because of bad elasticity or weak adhesion, breaks down under stress, rendering the coating brittle and the protective function reduced.
4. Denting or deformation
Denting is surface deformation without breaking, which usually happens on softer or thinner coatings and compromises the finish while offering less protection.
5. Surface Crazing
Crazing will be characterized by fine crack formation, indicating loss of toughness and deterioration of the film's overall integrity. Its susceptibility to further damage is enhanced.
