UV conformal adhesive is an adhesive that can cure quickly under ultraviolet irradiation. It is mainly used to protect electronic components from moisture, dust and chemical substances.It can be used for protection of circuit boards.
Â
Characteristics of UV curable conformal coating:
1.Fast curing: Under ultraviolet irradiation, it can be quickly cured in a short time to improve production efficiency.
Â
2.Good protective performance: It can effectively prevent moisture, dust and chemical substances from damaging electronic components and extend the service life of electronic equipment.
Â
3.High transparency: It has good transparency after curing and does not affect the appearance and marking of electronic components.
Â
4.High and low temperature resistance: It can still maintain stable performance in different temperature environments.
5.Environmental protection: generally does not contain harmful solvents and meets environmental protection requirements.
