About

Dubois Equipment has a dedicated lab facility to provide our customers with positive hands-on test results to maximize coating performance on virtually any substrate. Because the tests are conducted to achieve specific results with given substrates and coatings, it is preferred that customer personnel, and a representative from the coating supplier be present during the lab testing to assist in the evaluation of the results. An alternate function of our lab facility is that it is used for training of operators prior to equipment or system start-up. This allows the operators to receive “hands-on” instruction in an ideal training environment.

Lab Details

Where required for test purposes, variable speed controls are installed. Various roll covers are available to suit specific coating requirements. All laboratory equipment installed is suitable for processing parts having a maximum width of 24″ while part lengths may vary up to 48″, unless otherwise noted in the machine description below. For test purposes, part dimensions within these parameters may be processed, but for convenience in handling 12″ x 18″ maximum substrate sizes are recommended.

Lab Facility Equipment

• Differential Roll Coater: Complete with a sponge covered applicator roll. This machine is normally used for the application of stains, but may also be used for normal differential coating work.
• Combination Coater: Used for combination coating tests, or normal differential coating work with the second head in the raised position. A chrome plated steel roll is available for use in the second head to allow simulation of reverse roll filling operations.
• Curtain Coater: Gravity type, with swiveling head design.
• Vertical Edge Coater: Differential type, conveyor mounted, complete with  UV curing unit and scuff sanding wheel.
