EPOXYCAST EC-1850FT

Multimarket is pleased to announce that the EpoxySet EC-1850FT with EH-9 curing agent has recently passed NASA Outgassing tests.

Outgassing is the measure of the level of residual low molecular weight species that can be evolved at high temperatures. NASA outgassing has a specific set of standards to meet demanding applications (including water, if the material is not conditioned in a low moisture environment prior to testing).

Why is Outgassing a consideration? 

Outgassing can ruin performance on applications that operate under severe conditions (extreme temperatures, high to low pressure, chemical exposure, etc). Even small amounts of outgassing can affect sensitive applications. If parts on the instrument or nearby equipment release outgassed material to condense onto a precision instrument, performance can be dramatically altered.

Navigational instruments on automotive equipment (or anything with GPS really) are a good example of where outgassing can affect the performance of the instrument. Many optical applications are vulnerable as well, as outgassing can cause fogging on highly sensitive parts.

What does Multimarket have to offer?

EPOXICAST EC-1850FT/EH-9 is a highly filled, thermally conductive potting compound. When mixed, it creates a flowable, self-leveling liquid that can cure at room temperature or accelerated at elevated temperatures. EC-1850FT is used in a variety of applications including coil impregnation, motor stator potting and wherever thermal conductivity is needed.

EC-1850FT is a pourable resin system offering excellent heat transfer, high voltage insulation, low exotherm and minimum shrinkage. It has a lower viscosity than EC-1850FT. It rapidly transfers heat, eliminates hot spot, and increases the operating efficiency of most encapsulated devices. Its low shrinkage minimizes risk of damage to fragile components. It is useful for potting and encapsulating densely packed power supplies and hot components, integrated circuits, power and operational amplifiers, transformers and many types of semiconductors.

Below are results of NASA Outgassing test for EC-1850FT/EH-9, when cured at 65°C for 3 hours:

• Total Mass Loss (TML): 0.20% 
• Collected Volatile Condensable Materials: <0.01%
• Water Vapor Recovered (WVR) – 0.07%
