Dicronite® Dry Lubrication
Quick & Helpful Documents:
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 numerous industries
APPLICATION PROCESS DESCRIPTION
Dicronite® is applied at one of many licensed coating facilities. After surface preparation, Dicronite® dry lubricants impinged onto the substrate surface. The coating process is conducted at ambient conditions. The material includes no binders or adhesives and requires no curing. Dicronite® can be re-applied without extensive stripping.
COATING INFO
