DuPont Impact
Coating Film Impact Evaluation

The QM700D DuPont impact tester evaluates cracking, spalling and adhesion of coatings, films, plastic sheets or paint under drop-weight impact. A punch of specified radius is placed on the specimen surface and a standard weight is dropped from a fixed height; surface damage is visually inspected to rate coating adhesion and surface impact resistance.

From automotive paint to industrial coatings: whether a coating cracks or spalls on impact directly relates to its protective performance and appearance. Drop heights of 500/1000 mm in two stages adjustable at 50 mm intervals, plus 300/500/1000 g weights in three stages, make impact energy precise and reproducible.

Designed for coating impact evaluation: drop-weight impact plus standard weights; paint-film adhesion impact test.
