Electrolube Put Two Component (2K) Conformal Coating Materials to the Test

The performance requirements of conformal coatings continue to become ever more challenging, as electronics are increasingly subjected to ever more hostile operating environments.  Simultaneously, environmental legislation continues to evolve, with an emphasis on reducing solvent usage and Volatile Organic Compound (VOC) emissions. The use of solvent-less silicone conformal coatings is now mature, but often these materials cannot be used due to the…

Conformal Coatings Vs Potting Compounds Which is better to protect my PCB, a coating or a resin?

Tags: Encapsulation Resins, Conformal Coatings, 2K Range

This is a question that is often asked throughout the electronics industry and Like any good engineering answer, it depends… on the degree of environmental protection required. The first thing to consider is often the design of any housing within which the PCB will be enclosed. If an assembly is enclosed in a housing which is designed to be the primary environmental protection, then a conformal coating is often used to provide a back-up to the primary protection provided by the housing. Where the housing is not suitable or capable of providing primary protection of the assembly from its operating environment, then most times a resin might be a better choice. Read more >

High-Performance Resin Chemistries for Electronics Protection

Alistair Little, Technical Director of Electrolube’s global resins business, describes the different types of circuit and component encapsulating resins, providing some background on their properties and applications, with examples from Electrolube’s own product portfolio, which will be showcased at this year’s Electronica show.

Resins are widely used for potting and encapsulation in the electronics and electrical industries, and are generally found in three major categories, depending on their chemical types: epoxy, urethane and silicone.…
