Product Introduction
Electrolube HPA is a high-performance acrylic conformal coating specifically engineered for demanding applications in industries such as defence and aerospace. It is approved to MIL-I-46058C and formulated exclusively for professional use. The coating offers excellent clarity and transparency, making it ideal for LED applications exposed to ultraviolet (UV) light. HPA provides robust protection against environmental challenges, including moisture, thermal cycling, and mould growth, while ensuring high adhesion to various substrates. Its solvent-based composition allows for easy application via spraying, dipping, or brushing, with curing times adaptable to temperature conditions.
Enhanced Properties
Building on the parameters above, Electrolube HPA exhibits unique properties that enhance its performance in critical environments. Its excellent UV resistance and optical clarity ensure minimal degradation in LED and high-light-exposure settings, as confirmed by its transparency and resistance to yellowing. The coating is reworkable using Electrolube ULS solvent, allowing for easy removal and PCB rework without damaging components—a key advantage for military and aerospace maintenance. Additionally, HPA demonstrates superior adhesion to diverse substrates (e.g., metals and plastics), resistance to mould growth, and compliance with flammability standards (UL94-V1). The inclusion of a UV trace (375nm) enables post-application inspection for uniform coverage and thickness verification. These attributes are validated by MIL-I-46058C thermal cycling tests and moisture resistance certifications.
Application Scenarios
Electrolube HPA is primarily used in defence and aerospace applications, as specified in the TDS, due to its robustness in challenging conditions like thermal extremes and moisture. It is also ideal for UV-exposed LED systems, such as automotive lighting and outdoor displays, where clarity and UV resistance prevent performance degradation. Based on online research of the same product (e.g., from industry sources like Electrolube's official documentation and distributor sites), HPA is commonly applied in electronic assemblies for unmanned aerial vehicles (UAVs), missile guidance systems, and satellite components, where reliability under harsh environments is critical. Additionally, it is used in medical devices and industrial controls exposed to UV light or high humidity.
