A circuit board is a component with wiring installed by etching or other means on a board made of an insulating plastic resin (phenol resin, epoxy resin, etc.).
There are two types of circuit boards: rigid rigid substrates and soft flexible substrates.
The appropriate substrate is selected according to the application, and various electronic components are mounted on the substrate.
Resin coating or resin casting is sometimes used to waterproof or heat protect mounted components.
We offer a wide range of UV-curable, solvent-free coating paints and casting agents of various hardnesses that can be cured at room to medium temperatures.
Our Products
As we know general urethane has an excellent flexibility but it hydrolyzes by water, our product has excellent moisture resistance using a special urethane framework system against hydrolysis. Taking advantage of the characteristics, our urethane products are used to protect against environment and keep insulating various electronic components. We also have a wide range of products, from hard to soft, and the grades specialized for flame retardance, heat dissipation, heat resistance, and moisture resistance.
