Waterproof Plyurethane Conformal Coating for PCB PCBA
Waterproof Plyurethane Conformal Coating for PCB PCBA
Conformal coating is a thin protective film that is applied to electronic components and printed circuit boards (PCBs) to protect them from environmental factors such as moisture, dust, and temperature fluctuations. The coating conforms to the contours of the component, providing a uniform layer of protection.
Polyurethane conformal coating is a transparent modified polyurethane material. It is a highly reliable electronic protection material. It meets the latest requirements of the electronics industry. It can be cured quickly at room temperature and high temperature. It has low odor and does not contain aromatic components such as benzene, toluene and xylene. , meet the latest environmental protection and occupational health requirements, even in harsh environments, it still has good electronic protection performance, corrosion protection is particularly outstanding, has good voltage resistance and insulation properties, and has good performance in the fields of new energy, automatic control, automotive electronics and home appliances reputation and high market share.
Conformal coatings can be applied using various methods, including spraying, dipping, brushing, and selective coating. Spraying is a common method because it can be used to coat large areas quickly and efficiently. Dipping is useful for coating components with complex geometries, while brushing and selective coating can be used for precise application of the coating.
