Corrugator Krytox®DuPont™ 226 FG, 227 FGr

 
• High-Temperature Anticorrosion Greases for Corrugator Service
• These greases are the standard lubricant for grease lubricated high temperature bearings in corrugator service. They provide protection from rusting, high temperature corrosion, and wear while maintaining excellent lubricity over a broad temperature range. Corrugator Krytox® 226 FG and 227 FG are nonfl ammable, chemically inert, and provide for signifi cantly easier cleanup at roll change versus most other lubricants. Krytox® allows extended lubrication intervals and longer equipment life. Although normally provided in an NLGI Grade #2, other grades are available upon request. Typical applications include preconditioner rolls, single facers, and double backers.
