A. Doctor Blades for Coatings

・Plastic doctor blades → Reduces costs compared to existing blades
・Steel doctor blades are also available.
・Used by battery manufacturers

B. PP Single-Sided Tape for Processing Use

・Available as a thin film
・Products can be customized to customer requirements
・Available cut to thin widths

C. Cathode/Anode Filters

・Significantly boosts slurry filtering quality → Significantly reduces electrode manufacturing defects
・Longer life than existing filters → Lower component replacement costs
・Widely used by major battery manufacturers

D. Pressure Roller/Drive Unit Lubricating Grease

・Excellent heat (200°C), load, and wear resistance compared to standard mineral grease
・Extends lubricating intervals
- →(1) Lower component replacement costs
  - (2) Less frequent maintenance for increased productivity

E. Coiling Machine Lubricating Spray

・Oil-free, low-friction, normal temperature drying
・Reduces winding and drop-out problems to increase productivity → Lower labor costs
・Used by major battery manufacturers

Dry Room (Low Dew Point) Environment Lubricating Grease

・Consistent lubrication, even over extended service in low dew point and vacuum environments
・Chemical resistant (compatible with liquid filling processes)
・Safe and nonflammable (ambient temperature range: -20 to 250°C)
・Extends lubrication intervals.
- →(1) Lower component replacement costs
  - (2) Less frequent maintenance for increased productivity
・Used by major battery manufacturers
