Marmonix MHC-250 Paint Adhesion Cross-Cut Tester

Marmonix MHC-250 Paint Adhesion Cross-Cut Tester

The Marmonix MHC-250 is a cross hatch cutter for evaluating the adhesion of paint, powder coating, and other applied finishes. A cross-cut test creates a consistent pattern in the coating so the operator can assess how well the finish remains attached to its substrate. This simple method helps quality teams compare results across batches, materials, and production stages.

Use the MHC-250 on a suitable, clean test surface and follow the applicable test method for cut spacing, tape use, inspection, and rating. Consistent pressure, direction, spacing, and lighting make results easier to reproduce. The instrument is intended to support a controlled inspection workflow, so technicians should document the coating system, substrate, test location, environmental conditions, and observed classification.

Typical application

For example, a paint-line inspector can use the MHC-250 on a coated panel after curing to confirm that the finish meets the project adhesion requirement before shipment.

The MHC-250 suits incoming inspection, production checks, and laboratory surface testing. Keep cutting edges protected and clean the tool after use according to the instructions. Do not treat one test as a substitute for the complete specification; select the correct method and acceptance criteria for the coating and substrate being evaluated.

Store the cutter in a dry, protected place and train operators on the selected test standard. Good documentation helps teams trace adhesion results back to the material and process conditions that produced them.
