Consisting of a resin and a hardener, a two-component epoxy can be formulated to offer a wide range of mechanical, thermal and electrical properties. While mix ratios differ, they all offer the ability to cure at ambient temperatures or elevated temperatures for faster cures. Here are a few tips to help you mix and apply your two-part epoxy.
Electronics continue to be placed into harsher environments, and PCB component vibration dampening remains a challenge for many industries. When the solder connection strength is not going to be sufficient to withstand years of vibration, there is a solution: staking materials.
Numerous fields of industry manufacture products that are prone to high-vibration environments. Some of them are:
Have you ever wondered if you can use the same material to pot or conformaly coat your electronics? HumiSeal has launched a new fast curing, two-part silicone (Humiseal 2C51) that can be easily applied as a conformal coating or as a potting material. This option allows users to standardize on one product for multiple applications.
Humiseal 2C51 is a high solids, low viscosity, fast curing product. Humiseal 2C51 comes as a two-part kit. Part A and part B are mixed with a 1:1 ratio to either encapsulate or conformally coat your electronics. Part A and B are yellow and blue for easy verification of complete mix which is slightly turquoise. When cured, 2C51 is trasparent even in high thicknesses. Humiseal 2C51 is primarily used in high temperature applications where component stress relief is required.
