Choosing a reliable electronic epoxy encapsulant potting compounds from potting epoxy manufacturers
Manufacturers dealing with LED fabricators or other components must protect the parts. This means finding an ideal potting compound. The compound you pick influences the fabricated parts a lot. Knowing a few things about the compounds is important to make the selection process much easier.
Potting materials usually are in the form of liquid resins that are allowed to flow over the circuit board to offer the needed protection for the components. Some components and devices are potted to offer elements, impact, vibration, heat, and water.
Potting materials options
There are 3 most common potting materials. Each has its drawbacks and benefits.
Urethane and epoxy
These are the most commonly used materials for purposes of potting electronics. They offer protection because they are hard. The electronic parts remain well covered. The temperature tolerance of urethanes stands at 180 degrees. Epoxy stands at 250 degrees, but this depends on the specific products.
Urethanes and epoxies provide good adhesion and are not easy to remove. This is because they are very tough. They can protect intellectual property, making it hard to reverse-engineer some products. Your products remain safe from competitors.
One of the greatest things about this compound is its adhesion and strength. However, this is a weakness as well. Removing them becomes an issue once the potting has been applied. This means repairs can be very hard, and you may have to scrap the parts when repairs are needed.
The other issue is that these compounds are exotherms. Heat is produced as they cure. This heat can be rather high and can end up damaging components.
Silicone
These potting compounds have unique characteristics. There are so many fabricators in the electronic industry that use silicone. It comes with great benefits and is easy to use. Silicone allows repairability. It is very easy to remove silicone from parts. Every part can be removed without destroying the structure.
Silicone has good temperature Resistance as well. Modern components today usually get very hot and create temperatures that are more than what urethane and epoxy can handle. Silicone is one of the compounds that has the widest tolerance.
There are instances where electronic devices, applications, or components may be sunlight exposed. Silicone is a good choice because it offers great resistance and prevents yellowing and cracking, which is common with other materials.
Color temperature is one of the most important characteristics, especially for LED lights. However, the color you get at the end of the day is usually affected by the material used for potting. This color may be distorted or tinted.
The compound is very easy to assemble as well. The potting material flows with a viscosity that is fluid-like.
