Epoxy resins (ER) provide a thin protective film, just like any other conformal coating. Epoxy is available as a single-part or two-part compound. Single-part compounds are cured thermally or by ultraviolet (UV) exposure. Two-part compounds begin to cure as soon as they are mixed together.
Epoxy conformal coatings have good moisture and dielectric resistance. They also have excellent temperature and chemical resistance. Epoxy also has good resistance to abrasion and is rigid.
Read on for more information about the properties, benefits and applications of epoxy conformal coating.
Epoxy conformal coating has these useful properties:
As with acrylic, polyurethane, and silicone, epoxy can be applied by one of three methods:
A buffer should be considered for use with more delicate components since the polymerization process causes film shrinkage.
Epoxy is nearly impossible to rework. Any solvents that can remove epoxy conformal coating can also remove the epoxy adhering components to printed circuit boards. The solvents also affect the PCB epoxy-based laminates. The only possibilities for rework ;are spot removal with a very minimal amount of solvent or burning through the coating with a knife. Heat cure causes the coating to shrink, and a low-temperature cure or another method is recommended if shrinkage is an issue.
Epoxy resin protects from various harmful factors such as:
This level of protection makes epoxy conformal coating suitable for many applications. For example, it is used for small, complex electronics because the coating is more streamlined than the traditional bulky enclosures. For PCBs, the epoxy coating can keep out heat from other devices. Epoxy can also prevent technology theft and provide fire hazard protection.

Epoxy coating has many benefits, such as:
Whether you use the single-part or two-part epoxy compound, both systems provide the same benefits.
If you need a rigid formal coating that can withstand physical abrasions and chemical exposure, choose Diamond MT as your epoxy coating company. We are known for our quality services, including epoxy coating application. From applying the coating to curing, we can have your order ready for you in two to five days — the fastest turnaround in the industry.
Our technicians have perfected the epoxy application process to ensure each coating provides full coverage and is the correct thickness. If the coating is too thick, problems could include shrinkage, cracking, bubbling or trapped solvent. Here at Diamond MT, we are the experts at applying conformal coatings, from handling your invaluable piece of technology to application to quality control and standards.
Our technicians can also rework and remove your epoxy conformal coating if required. While epoxies are very good at protection from humidity, chemical and abrasion, they are, as stated above, very difficult to remove. Below is a brief description of some methods for removing this robust coating:
