StayClean-RWater-soluble Additive
Conserving Water While Preventing Corrosion
Prevents Corrosion by DI water
The active component in StayClean-R continuously attaches itself to the surface of the metallic layer (e.g. bonding pads), reducing incidences of corrosion-causing contact between the DI water and the metallic layer.
Can Be Used in Combination with a DI Water Recycling Unit
The molecular size of the active component in StayClean-R is smaller and better optimized for
ion-exchange resin. It also enables ion-exchange and ion-removal, which is necessary for producing DI
water.
Thus, it conserves water while preventing corrosion, and it is also compatible with the DWR series.
Reduced Bonding Pad Defects
StayClean-R exhibits a high corrosion prevention ability, even when diluted up to a maximum of
1:10,000, preventing corrosion during lengthy-processing at a low cost.
StayClean-R also excels in cleaning performance, with no concerns for residue on the wafer.

Optimized for Ion-Exchange Resin
- Adjust the the molecular size of the active constitute in StayClean-R
- Ions Can be exchanged
Like other molecules, The active constitute of StayClean-R is normally adsorbed to the ion exchange resin
Recommended System Configuration
Compared to existing corrosion inhibitors, the environmental load of StayClean-R is very low and it is
able to suppress drainage treatment costs.
Furthermore, using StayClean-R in combination with DWR enables zero-drainage operations.
Only the water is circulated in this system, without any StayClean-R components inside the wastewater.
