EPO-TEK® Low Outgassing Adhesives
This technical piece details the specifications and appropriate EPO-TEK materials available to meet stringent guidelines necessary in critical designs.

What Is Outgassing?
Outgassing is a measure of the level of residual low molecular weight species (including water if the material is not conditioned in a low moisture environment prior to testing) that can be evolved at elevated temperatures.

How Is It Measured?
One method for measuring levels of outgassing is Thermal Gravimetric Analysis or TGA. This technique measures very small weight changes in a material as a function of temperature. The resultant percent weight versus temperature curve is then used to determine the weight loss or outgassing at specific temperatures. Below is an example of a typical weight loss vs. temperature scan.

What Are The Standards?

  • NASA ASTM E595
  • MIL-STD 883/5011
  • TelcordiaGR-1221
