Personal safety must be the first and foremost consideration in using any chemical compound including Epoxy or Polyurethane products.
We are constantly learning, almost on a daily basis, about various products being banned, taken off the shelf of supermarkets because of their recently discovered adverse effects. Widely used consumer products seem to be in the news more frequently while re-classified industrial products tend to be less publicized.
Coefficient of Thermal Expansion (CTE) is a measure of the expansion or contraction of a material as a result of changes in temperature. Most frequently it is provided as linear CTE but some times given as volumetric CTE.
The VPI CAST coating system is easy to apply and provides maximum design flexibility for coil designs while providing complete environmental protection.
Thermal conductivity is an important consideration in potting or casting electronic modules containing heat generating components. The heat being generated in operation by the various devices must be dissipated in order not to exceed the maximum operating temperature limit of the most sensitive component in the circuit.
Castable Urethane ELASTOMERS are materials which can be stretched and will recover instantaneously on release. They are thermosetting, as are natural and synthetic rubbers. In simple terms, an Elastomer is a material which can be stretched at room temperature to twice its own length, held for five minutes, and upon release, will return to within 10% of its original length over a period of time.
