  • Best Practices for 3M TC-2810

    *See Terms of Use Below

    1. Application

      3M™ Thermally Conductive Epoxy TC-2810 is supplied in dual syringe plastic duo-pak cartridges as part of the 3M™ EPX™ Applicator System. The duo-pak cartridges are supplied in a 37 ml configuration. To use the 37 ml cartridge simply insert the duo-pak cartridge into the EPX applicator and start the plunger into the cylinders using light pressure on the trigger. Next, remove the duo-pak cartridge cap and expel and discard a small amount of adhesive to be sure both sides of the duo-pak cartridge are flowing evenly and freely (ie: no voids, “plugs of adhesive”, dis-continuity in flow, etc.) Once even side to side and uniform flow from both sides of the duo-pak is confirmed, attach the 3M™ EPX™ Mixing Nozzle to the duo-pak cartridge to ensure proper and uniform mixing of the Part A and Part B and begin dispensing the adhesive.

      With a 200mil cartridge, the nozzle must be attached before dispensing any material to prevent unmixed adhesive from getting into the applicator cartridge holder. A quantity of material should be dispensed through the mix nozzle and discarded until a uniform color, consistency of product, freely flowing and even side to side flow is evident.

      Partially used cartridges must follow the above use instructions to ensure consistent product performance.

      Complete and uniform mixing as noted above of the two components is required to obtain consistent product performanc.
