The MEK Rub Test Machine is a semi-automated, pneumatic testing device built by DJH Designs to evaluate coating durability and solvent resistance. A constant-pressure dead weight rubbing block removes the inconsistency that comes with manual double-rub testing, giving repeatable, standardized results from the lab bench to the production line — while keeping setup and operation simple. Because the machine runs entirely on compressed air with no electrics, it’s intrinsically safe and keeps operators away from direct solvent contact during testing.

A 425cc solvent reservoir with automatic shutoff and an adjustable solvent flow metering valve keep consumption to a minimum, while the quick-change solvent pad system speeds up test preparation between runs. A programmable stroke counter (1–9999) tracks double rubs precisely, and front panel mounted controls keep operation straightforward. The machine is ASTM D7835 compliant and CE certified, and optional accessories — a dual reservoir, a variable stroke kit, and a variable weight head — extend it to non-standard panels and both ASTM and EU testing requirements.


Key Features Specifications Applications Options & Accessories Download Documents
✓
Easy to Set Up, Simple to Operate — minimal training required to get consistent, repeatable results from the very first test.
✓
Constant Pressure Dead Weight Rubbing Block — applies uniform force on every stroke, removing operator-to-operator variability from the test.
✓
Front Panel Mounted Controls — all operating controls are accessible from the front of the machine for straightforward day-to-day use.
✓
Adjustable Solvent Flow Metering Valve — fine-tune solvent delivery to the pad, minimizing solvent consumption over repeated tests.
✓
425cc Solvent Reservoir with Automatic Shutoff — shuts off automatically to prevent overfilling and reduce unnecessary solvent exposure.
✓
Quick-Change Solvent Pad System — speeds up test preparation between runs and keeps operators focused on other QC tasks.
✓
Programmable Stroke Counter (1–9999) — precisely tracks double rubs per test, so results are documented exactly to specification.
✓
Intrinsically Safe — All Pneumatic Operation — no electrics on the machine — it runs entirely on compressed air, reducing ignition risk around solvents.
✓
Reduces Operator Exposure to Solvents — automated dosing and dead weight rubbing keep hands and skin away from direct solvent contact.
