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.

Leveling Agent

Most coating systems need good leveling and flow in order to have a nice appearance. Controlling the leveling and flow of a coating is all about controlling the surface tension of the system. A good leveling agent has low surface tension and low surface tension gradient.
