Please note that epoxy resins are prone to solidification or crystallization. If this occurs, the product can easily be returned to a liquid state by immersing the tube in warm [approximately 100 °F (38 °C)] water for 30 minutes. Ensure all material is melted prior to use. Allow the resin component to return to room temperature prior to mixing with the hardener.
This epoxy resin is classified as a dangerous good in some countries. Depending on the delivery location, this item may need to be shipped separately from the rest of your order at an additional charge. Please contact our sales department if there are questions or concerns when placing an order for this item.
EPO-TEK 353ND is known industry wide as a high temperature epoxy. This two part, 100% solid, heat curing epoxy can be used in applications requiring constant performance at temperatures up to 250 °C. It can handle 250 °C to 350 °C for brief periods. The epoxy is vacuum compatible and passes NASA low outgassing standard ASTM E595. Thorlabs offers 353ND epoxy in pre-measured, 4-gram packs that provide repeatable performance and eliminate the need for measuring.
This silicone grease is very popular as a general laboratory lubricant and is commonly used as a stopcock grease, to lubricate synthetic or silicone rubber gaskets, or at glass-to-rubber boundaries. However, it should not be used on fluorosilicone O-rings and gaskets. In addition, the lubricant can also be used for a wide array of non-vacuum applications such as the lubrication of water-treating equipment, general laboratory equipment, or O-rings for binoculars and telescopes.
This Apiezon grease, which is ideal for re-lubricating the leadscrew threads of our Z8, ZFS, and ZST actuators, has excellent anti-seize properties. It contains PTFE for higher lubricity, is recommended for both general use and vacuum applications down to 10-9 Torr, and has an optimal working range of 10 °C to 30 °C (50 °F to 86 °F). The grease comes in a syringe for easy application.
Note: It is recommended that the leadscrews of the Z8, ZFS, and ZST motors be lubricated every 50,000 cycles or 6 months.
