Electrolube’s resins expert, Alistair Little, returns to the subject of potting and encapsulation resins with this Q&A guide to some of the problems you are likely to encounter, how to overcome them and what you need to know when selecting an appropriate material for your application.

When I last broached the subject of potting and encapsulation resins, I went into some depth on the subject, explaining their chemistries and physical properties, how they behave when being mixed, applied and cured. For this column, I’m going to…

Electrolube’s Alistair Little takes a closer look at some of the more ‘testing’ and technically probing questions that he receives from its customers in his latest blog on potting and encapsulation resins.

In my latest series of blogs for Electrolube, I have focussed on answering ‘five top tips’ for design engineers such as five common FAQ’s, and five…

How To Protect PCBs from Harsh and Challenging Environments

In this months blog, I thought I would continue with my theme of five ‘Top Tips’ for circuit designers and manufacturers who seek to ensure that the in-service reliability and longevity of their electronic assemblies and products are fully addressed.

1First, think very carefully about the sort of environment your PCB is likely to encounter. It is easy to ‘over-engineer’ a product in order that it will survive the very worst of conditions, but ‘worst conditions’…

I have been working with polymers and resins for more than 20 years now and, modesty aside, have been involved in a number of significant developments ranging from structural composite resin and pre-preg systems for the aerospace and automotive industries, to my current activities with Electrolube and a strong team of chemists, formulating new resins for the protection of modern electrical and electronic assemblies.

Over this period, the electronics industry has witnessed an extraordinary rate of technological change - and we chemists…

To encapsulate or to coat: that is the question

Posted on 02 October 2017 by Alistair Little
Tags: Encapsulation Resins, Knowledge Base, FAQ

Potting compounds and encapsulation resins are generally two-part systems, in which a resin is mixed with a hardener in a precise ratio to form a cross-linked polymer when cured. It’s also possible to add mineral substances (‘fillers’) to resins to improve their performance under certain operating conditions. Like conformal coatings, most resins will cure at room temperature, and while this can be a relatively slow process in the case of potting resins, cure time can be reduced by applying heat.

An important thing to be aware of when…
