Cold light source, no heat radiation, low temperature rise on the surface of the illuminated object, solving the traditional thermal damage problem. Especially suitable for liquid crystal edge sealing, film printing, etc.; The LED UV lamp needs to be as close to the surface of the cured object as possible. The closer the distance, the better. It is best to keep it within a distance of 0.5-1 cm. Too far irradiation distance will seriously affect the curing effect; Different coatings will take the same time to cure
