What Are the Types Of High-Temperature Epoxy Used for Electronics?
When choosing a high-temp epoxy for electronics, it’s important to consider various types based on their properties. Each type offers different benefits suited for specific electronics applications, including epoxy high temperature, heatproof epoxy, and temp-resistant resin solutions. Below are some key types of high-temperature curing epoxies.
1) One Part vs Two-part Epoxy
One-part epoxy is a pre-mixed formulation that is ready to use out of the package. It typically cures when exposed to heat, making it ideal for electronics-safe epoxy applications that require straightforward application. It is often used in cases where precision is less critical and where a temperature-stable epoxy is needed for general protection.
On the other hand, two-part epoxy requires the mixing of resin and hardener before application, allowing for more control over curing time and strength.
This type of epoxy is preferred in more demanding applications, providing better adhesion and durability, especially in environments with high temps. It is widely used in electronics for bonding and coating sensitive components.
2) Thermally Conductive Epoxy
Thermally conductive epoxy is specially designed to provide excellent heat dissipation while offering the usual epoxy high-temperature benefits.
