• I'm trying to replace a competitor material. Does Epoxy Technology have a competitor cross reference chart?
  Yes, but we choose products by application first in addition to matching performance properties stated on competitors data sheets. Please consult our Application Experts at (978) 667-3805 or techserv@epotek.com to discuss your specific requirements.
• For EPO-TEK® H20E, why are there two different thermal conductivity values listed on the data sheet?
  The main difference between the 2.5 W/mK and 29 W/mK thermal conductivity values listed on the data sheet for EPO-TEK® H20E is test method. The first value of 2.5 W/mK was measured using our standard laser flash test equipment, in accordance with ASTM E1461. This involves using a disk of material that is approximately 12.55mm in diameter and 1mm in thickness. It provides a bulk property and does not reflect the actual performance of the material in a given assembly. The second value, 29 W/mK, reflects actual measured circuit value from a power TO-18 device. This was back calculated using the thermal resistance determined in the device with a 2mm x 2mm chip and a 75um bond line.

  If you have additional questions, please consult our Application Experts at (978) 667-3805 or techserv@epotek.com.

• My epoxy looks like it separated. What should I do?
  It may be settling of the filler which can be a common phenomenon. Most of the time, the filler can be incorporated back in with some gentle mixing. It is good practice to stir a filled system before each use to ensure the filler is evenly dispersed within the epoxy matrix before using. A method for preventing this filler settling, is to store the closed epoxy container on a jar roller to keep the material evenly suspended within the system.

• What is your standard procedure for running viscosity?
  We perform viscosity readings based on ASTM Test Method D2393 using a CPE 51 cone and plate on a Brookfield HBT viscometer. The sample size is 0.55cc where the material is allowed to equilibrate for 6 minutes in a water bath set at 23°C +/- 0.1°C.
