Scrape & Intercoat Adhesion Tester

The Scrape & Intercoat Adhesion Tester is testing equipment built by DJH Designs to evaluate shear bond strength between layers in a coating system — a failure mode that typical online adhesion checks are not designed to catch. It works equally well as an in-line production instrument monitoring adhesion in real time, or as a laboratory development tool for establishing the quality standards a coating system needs to meet before it goes into production.

Because it tests both substrate-to-paint and interlayer adhesion, the tester identifies weak bonds that standard flexibility and adhesion checks can miss — the kind of weakness that only shows up as paint removal once a part is exposed to real-world shear stress. Built with durable, production-floor-ready construction and a consistent 50 mm/sec travel speed, it’s suited to coil coating production facilities, paint manufacturer quality control, and multi-layer coating system evaluation alike.
