Photoinitiators are widely applied to the UV surface curing system with high photocuring speed and anti-yellowing, such as UV curing coatings, UV photocopying varnish, UV plastic coatings, UV wood coatings, UV glue, silk screen printing inks, lithographic printing inks, flexo printing inks, UV curing adhesives, optical fiber coatings and electronic products, generally used with other photoinitiators. It also can be used together with ultraviolet absorbent when necessary to prevent product aging.
Advantages:
1. Fast photocuring speed
2. Have light-decolourizatio
3. Can be used for thick coating curing
4. Belongs to low-volatility, mild-smell and environment friendly product
5. Anti-yellowing
