Extreme environmental protection for modern electronics is always an uphill task. The robust defense against shock, moisture, and temperature fluctuations must assure survivability for components over a considerably long period. In other words, this vital protection is achieved through potting, where electrical assemblies are encased in liquid polymer that solidifies. Reliable Two Component Potting Epoxy is normally the industry standard to achieve this highest level of protection. This system provides engineers with a versatile, high-performance barrier that is crucial for device durability.
Chemical Curing Process
The effectiveness of a two-component epoxy depends completely upon its two components: Resin Part A and Hardener or Curing Agent Part B. When these two components are mixed in the correct ratio, a vigorous exothermic chemical reaction is initiated, allowing the mixture to fully penetrate all geometries within an electronic housing before cross-linking. The result is a void-free encapsulation. This cured mass will then give very good mechanical support, serving as a shock absorber against impacts and vibrations while providing excellent adhesion to most component surfaces.
Key Protective Benefits
The resultant cured epoxy provides several very important features for an electrical assembly: firstly, providing excellent dielectric strength, thereby insulating the wires and conductors and avoiding any sort of short circuits, mainly at high voltage; secondly, constructing a formidable barrier to moisture, dust, and corrosive chemicals, thus maintaining the functionality of the assembly in a harsh industrial or outdoor environment; lastly, depending on the formulation, the Two Component Potting Epoxy may offer thermal management through dissipating heat away from important components, thus extending the life of the electronics.
Sourcing and Application
The selection of the appropriate potting epoxy depends on the specific needs of the application related to temperature tolerance, required viscosity, and curing time. The choice must fall on a high-quality, specialized formulation to ensure the best performance, without settling for general solutions.
