EPO-TEK® Glossary Of Terms

 

Halo
A bright or dark ring around a drop of molten solder on a flat surface.
Hardener
A substance or mixture of substances added to an epoxy resin to promote or control the curing reaction by taking part in it.
Heat Distortion (Deflection) Temperature
The temperature at which a material softens enough to distort under a given load. It is not usually considered to be beyond the maximum usable temperature, but is an indication of the maximum usable temperature when the material is load bearing at a given load. As the load decreases, the maximum usable temperature will increase.
Heat Sink
Any device that absorbs and draws off heat from a hot object, thereby neutralizing the extreme temperature.
Hermetic
The sealing of an object so it is airtight.
Hertz
One cycle per second.
Humidity (Absolute)
The amount of moisture present in the atmosphere expressed in grams per cubic meter.
Humidity (Relative)
The ratio of the amount of moisture contained in the atmosphere to the amount of moisture that can be carried in the atmosphere at a given temperature. Relative humidity is expressed in percent, e.g., 75% R.H. at a given temperature means that the air is 75% saturated with moisture.
Hydrophilic Solvent
Refer to "polar solvent."
Hydrophobic Solvent
Refer to "nonpolar solvent."
Hygroscopic
A property of absorbing and holding moisture. Back to Top

See Hertz.
