Application and Product Use Notes
For bonding rigid to rigid parts it is suggested that the bond line thickness and edge fillet be designed to optimize:
ii) Thermal Resistance.
A typical suggested bond line is in the 3-7mil thickness range
For improved thermal performance (lower Thermal Resistance), a thinner bond line is suggested. A thinner bond line can
reduce the bond strength so each application needs to be tested to find the correct balance between:
“Bond Line Thickness vs. Thermal Resistance vs. Bond Strength”
out past the side edges. Fillets can add strength to the assembly.
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 performance.

Use only 3M™ EPX™ Applicator and Mix Nozzles to ensure optimum product performance.
i) Bond Strength;
A “fillet” at the edges of a bond line is suggested to increase bond strength. The fillets are formed as the epoxy squeezes-
