DuPont ™ Krytox ® performance lubricants Corrugators User’s Guide Safe Handling For detailed information, refer to MSDS No. DU008134 Krytox ® GPL-22X series fluorinated grease. Highlights are: • When handling, wear any type of impervious rubber gloves. • Wash hands well before smoking cigarettes. Krytox ® transferred to the cigarette wrapper paper, burned (over 343°C [650°F]) and fumes when inhaled, may produce a transient, flu-like condi- tion known as polymer fume fever. • When handling Krytox ® HC Cleaner (MSDS No.10127PP), use adequate ventilation and wear eye protection and any type of impervious rubber gloves. Key Points • Make sure the bearings are clean and free of hydrocarbon oils, greases, and residues before lubricating with Krytox ® ; use Krytox ® HC Cleaner or equivalent. Contaminating Krytox ® with any other lubricant will impair its lubricating value. • If using pails of Krytox ® vs. cartridges, slight pooling of oil on top of the grease can occur, particularly if it has been sitting unused for a while. Simply mix it back in with a clean stirrer. • Use special grease fittings—pin or button head— for Krytox ® to prevent contamination with hydro- carbon or synthetic lubricants. • Use a dedicated grease gun (labeled Krytox ® grease only) with a swivel coupling matched to the special pin or button head grease fittings (bearing inlet ports). Fill the bearings and bearing housings completely to prevent air pockets that can collect water and debris. • Prevent corrugating process materials (e.g., waxes and paper debris) from entering the bearings.

Krytox® transferred to the cigarette wrapper paper,burned (over 343°C [650°F]) and fumes wheninhaled, may produce a transient, flu-like condi-tion known as polymer fume fever.
• When handling Krytox® HC Cleaner (MSDSNo.10127PP), use adequate ventilation and weareye protection and any type of impervious rubbergloves.
Key Points• Make sure the bearings are clean and free of
hydrocarbon oils, greases, and residues beforelubricating with Krytox®; use Krytox® HC Cleaneror equivalent. Contaminating Krytox® with anyother lubricant will impair its lubricating value.
• If using pails of Krytox® vs. cartridges, slightpooling of oil on top of the grease can occur,particularly if it has been sitting unused for awhile. Simply mix it back in with a clean stirrer.
• Use special grease fittings—pin or button head—for Krytox® to prevent contamination with hydro-carbon or synthetic lubricants.
• Use a dedicated grease gun (labeled Krytox®
grease only) with a swivel coupling matched tothe special pin or button head grease fittings(bearing inlet ports). Fill the bearings and bearinghousings completely to prevent air pockets thatcan collect water and debris.
• Prevent corrugating process materials (e.g., waxesand paper debris) from entering the bearings.

Relubrication• Wipe the inlet fittings clean with a clean cloth to
prevent contamination of the Krytox® grease.• Add/replenish Krytox® every three months. Pump
about 1 lb (1/2 cartridge), or whatever is neces-sary, of Krytox® grease into the bearing button orpin head grease fittings to force some existinggrease out through the seals. It is best to rotatebearings while adding grease to prevent “channel-ing” of the new grease through the bearing. A
more conservative approach is to follow thispractice more frequently, say once a month;proportionately less Krytox® would be needed.Pay attention to plant safety procedures whenworking with moving equipment.
• Compare expelled/purged grease with the “ColorGuide” and service as noted. (This guide applies tonormal wear only; contaminates will alter thegrease’s appearance.)
Color Contamination Recommendation
White None Grease in good condition: creamy consistency.
Gray 0.0–0.1% iron Grease in good condition, normal wear in bearing; creamy consistency.
Tan 0.1–0.4% iron Add grease until cavity is full, bearing OK.
Brown 0.4–0.8% iron Flush bearing with grease until color lightens to tan.
Dark Brown Greater than 0.8% iron Check bearing for play and noise. If OK, flush/purge with new Krytox®
grease. If not OK, schedule bearing change.
Black Replace bearing.
• Properly dispose of used Krytox® grease purgedfrom outlet ports, seals, and/or shaft-bearingclearances according to local, state, and federalcodes.
• Wipe off excess Krytox® grease from equipmentsurfaces to prevent buildup of dirt/debris attractedto surface grease.
• Keep all Krytox® grease containers covered toprevent contamination.
