Frequently Asked Questions
These are some of the most common questions that we get asked here at NanoSlick Lubricants
Most processing times for orders are 3-5 business days, large orders can take longer. If you are concerned about meeting a specific delivery time then you should contact us at firstname.lastname@example.org to inquire.
The Tungsten Disulfide (WS2) coating is thermally stable between -460°F to +1200°F.
Sharp objects can remove the coating and in harsh dusty environments the life of the coating is decreased.
Tungsten Disulfide (WS2) is not electrically conductive and in low voltage (mil amps) there can be some resistance. Our experience with gold plated balls used in switches with 1/2 volt power produced enough insulation to enable useful operation of the switch.
Tungsten Disulfide (WS2) is best applied on metal surfaces but can be applied to rubber as well as polyimide plastic retainers which had good success when coated as part of an assembled bearing. Glass and ceramics are not good candites for the coating.
Uniform thickness of Tungsten Disulfide (WS2) can be maintained because the material will not stick to itself which leaves the coating thickness to be determined by the particle size (1/2 micron thick).
Surface roughness is not a factor, a clean and non-oxidized surface is the normal surface. Excellent coating adhesion can be achieved on Ra finishes as fine as 2.
Laser markings will not affect the color or performance.
When Tungsten Disulfide (WS2) is applied to head tooling, gears, bearings, bushing and related components the noise level and energy consumption are reduced and spindle speeds are increased without chatter.
Yes, specific areas can be coated with fixturing and masking.
The best low friction and extended wear life results have always been achieved when all matting surfaces are coated. However, only coating the balls is also done on some applications with good results. The uncoated areas do not exhibit any detrimental effects.
Tungsten Disulfide (WS2) is completely compatible with all greases and oils. It is frequently used with high temperature greases in steel mills and rolling mills at aluminum plants.
The best results are achieved when individual components are coated but very good results can also be achieved on fully assembled items.
Tungsten Disulfide (WS2) is not a corrosion inhibiting coating, it will slow down the process but will not add any significant resistance.
Increasing the coating thickness does not increase the life or functionality of the coating.
The coating can be removed with acids or high alkalines. Tungsten Disulfide (WS2) does not crack or peel off. In a non-abbrassive environment the coating is permanent. On an injection mold running non-abbrassive resins 24/7 it will last 12-14 months.
Tungsten Disulfide will maintain a mirror finish to produce clear parts.
Five (5) year recommended shelf life when stored in the original container and in reasonable ambient conditions.
