Product Description
Coomcool GDW 220 is specially formulated slideway lubricants to provide all-round performance with good stick-slip and load carrying performance. They combine controlled frictional characteristics with high film- strength and high load carrying properties to eliminate ‘stick-slip’.
Advantages
- Good lubricity – prevents stick-slip of slideways.
- High load carrying capacity – prevents wear of highly loaded slideways.
- Good demulsification and cutting fluid compatibility – can be used in the presence of water or water based metalworking fluids.
Applications
Coomcool GDW 220 is formulated for use with heavily loaded slideway applications or where there is a vertical or inclined slideway.
