PRODUCT DESCRIPTION

Dicronite® is a tungsten disulfide (WS2), solid lubricant coating. This extremely thin film coating provides friction and sliding wear reduction that improves performance in various applications across industries.

APPLICATION PROCESS DESCRIPTION

Dicronite® is applied at one of many licensed coating facilities. After surface preparation, Dicronite® dry lubricant is impinged onto the substrate surface. The coating process is conducted at room temperatures. The material includes no binders or adhesives and requires no curing. Dicronite® can be re-applied without extensive stripping.
