MSK-HRP-MR100DC is a UL/CSA ready electric rolling press with variable speed 24VDC gear motor and UL certified switch power supply, which can be used from 110V- 220VAC under Argon gas glovebox. It has dual rollers of 100 mm Dia. x 100mm width and is an ideal rolling press for preparing electrode sheets for Li-Ion batteries research after coating and drying. (Since 11/29/2016, MR100DC ceramic coated roller option is available.)

|
| Application Notes |
- MSK-MR100DC roller can be used under Ar or N2 gas glove-box
- Must use acetone to clean and dry rollers' surfaces after each use to avoid rusting
- Apply anti-rust lubricant on roller surface if the machine were to be unused for a long period of time
- Never rolls materials with hardness > 50HRC
- Min. thickness for each rolling is dependent on the materials. Here are some results from our test:
- Please refer to this instruction on how to calculate rolling pressure from the roller gap (reference only)

Warnings
![]()
|
- The machine is not designed for thick metallic material. Click pic left for the rolling machine for metal
- In order to prolong the lifespan of the roller bearings, regular lubrication is recommended
- Multi-step thickness calendaring needed: While calendaring the sample sheet, make each calendaring decrement of 0.02mm compared to the sheet original thickness
- Never calendaring decrement over 0.02mm compared to original sheet thickness each calendaring.
- Must clean roller surface after each rolling and lubricate when not in use to avoid corrosion
-
It is not allowed to use any MTI product in any hazardous location, especially prohibited from using in Class I environments (flammable gasses & vapor)
