Types of Slip

Generally, slip can be divided into 2 types:

  • Dry type : Dry type gives a very soft feeling to hand and has fewer tendencies to leave any visible finger print on the panel.
  • Oily type : Oily type generally gives much higher slip at lower dosage but easily leaving a finger mark after been touched.
