13.5.3 Resistance of OS4 surface treatment to cleaning agents
SEW-EURODRIVE has had the resistance of the base coat and top coat of the OS4
surface coating independently tested and certified for cleaning agents and disinfectants
from leading manufacturers.
Providing these recommended cleaning agents and disinfectants are used and that the
specified cleaning intervals, temperatures and cleaning schedules are complied with,
the best possible results can be achieved with ASEPTIC gearmotors in terms of service
life and performance.
The following prerequisites were applied to the testing cycle:
• The testing cycle (1500 cycles) simulated daily cleaning according to product-
specific instructions for a time period of five years.
• Evaluation took place approximately 7 days after regeneration.
• Evaluation of visual changes (color, degree of lustre) and changes in protective
properties according to DIN EN ISO 4628-1.
• OS4 coating system on steel or aluminum base.
• Cleaning agents supplied by Henkel-ECOLAB
