So far for me normal cosmetic vaseline I stole from my girlfriend worked best.
I've put it on few weeks ago and it's still there. Keys are still sliding nice wherever I press them.
DESCRIPTION:Molykote EM-30L Grease is a synthetic hydrocarbon oil / lithium soap light consistency grease containing specially formulated solid lubricants. It has excellent compatibility with plastics such as polycarbonates, polyamides, polyacetals, and polybutylene terephthalates (PBT). It is a high-performance white synthetic grease with solid lubricants for extreme pressure, for use with plastic/plastic, plastic/metal, plastic/rubber and rubber/metal combinations involving slow and medium-fast movements and medium to heavy loads. May also be used for some metal/metal lubrication in electromechanical applications such as automotive actuators.COMPOSITION:Polyalphaolefine Synthetic Hydrocarbon; Lithium soap; PTFE (Teflon or equivalent) and other solid lubricants.APPLICATIONS:Suitable for lubrication points with medium to heavy loads and low to medium speeds.- Switches: Lubrication of plastics and electrical contact.- Actuators: Lubrication at wide temperature and various materials.- Micro Motors: Lubrication at wide temperature and various materials.- Office Equipment: Lubrication of Paper Feeding/Ejection Gears, Paper Adjust Actuators, Plastic Gears, Paper Sorting Unit Gears and other moving plastic parts.FEATURES:- Contains no lead or nickel.- Contains PTFE (Teflon or equivalent)- High load-carrying capacity.- Suitable for long-term lubrication by virtue of low oil evaporation and low tendency towards oxidation.- Low friction coefficient.- Compatible with most plastics and elastomers.- Can be used for plastic-plastic contact, metal-metal contact and plastic-metal contact long service life.- Low seepage, so it can be used in places where cleanliness is required.- Does not contain silicone therby preventing problems with contact point failures.SPECIFICATIONS:COLOR: WhiteNLGI Class: NLGI 1TEMPERATURE RANGE: From -49ºF to 302ºF (-45ºC to +150ºC)WORKED PENETRATION: 310-340 mm/10BASE OIL VISCOSITY @ 40ºC: 90 mm2/sSOLVES THESE LUBRICATION PROBLEMS:Plastic Gear Wheels in Enclosed Gears:- Running-in damage, stick-slip, scuffing, seizure.- High wear and short life owing to high temperatures or heavy loads. Swelling, range shrinking, stress cracks, change in strength characteristics due to inadequate lubricant.Seals and Packings:- Shrinkage, swelling and stress cracking due to lubricant incompatibility.Sliding Contact Bearings Made of Plastic:- Running-in damage, stick-slip, scuffing, seizure.- High wear, stiff operation, stress cracks, swelling, shrinking, effect on hardness due to inadequate lubricant, short life owing to high temperatures or high loads.Linear Sliding Guides:- Scuffing, scoring, high wear, short life due to high load.
