Dupont Impact Tester

The Dupont Impact Tester is a standardized testing device used to determine the impact resistance and flexibility of coatings, paints, plastics, and other materials. It simulates the effect of a sudden impact or drop on a coated surface using a falling weight from a fixed height. Widely used in quality control and research laboratories, it ensures coatings can withstand real-world mechanical stress.

Key Features:

Test Method: Falling weight impact (vertical drop)

Drop Height: Adjustable (commonly up to 1000 mm)

Weights: Interchangeable impact weights (e.g., 0.5 kg to 2 kg)

Impact Head (Punch): Rounded tip (standard sizes available – e.g., 1/2", 5/8")

Anvil Support: Hardened steel base for accurate test results

Scale Markings: Graduated scale for precise height setting

Construction: Rigid frame with anti-corrosion coating

Operation: Manual or semi-automatic (depending on model)

Sample Size: Accommodates standard test panels

Repeatability: High repeatability and consistency in results

Standards Compliance: ASTM D2794, ISO 6272

Applications:

Evaluation of impact resistance of paint and powder coatings

Testing plastic films, laminates, and sheet materials

Adhesion and flexibility testing for automotive, appliance, and industrial coatings

R&D and QC in coating, paint, and polymer manufacturing industries
