I. Application
It is suitable for various power curing lamps that use ultraviolet light to irradiate special coatings, paints, inks, glues, 3D printing materials and other substances to cause chemical reactions to rapidly cure.
II. Product Features
The high transmittance of the ultraviolet region makes the product’s effective spectrum use efficiency high, high purity, extremely low OH level (less than 1ppm) and special cleanliness control to ensure that the product can be used continuously under high temperature, high pressure and high power.
III. Product Type
WQPQ184，Quartz tube for curing lamp
