Details

It is a highly efficient free radical (1) type light, a highly efficient photoinitiator that absorbs over a long wavelength range.Due to its wide absorption range, its effective absorption peak is 350-400nm, and it has been absorbed to about 420nm. Its absorption peak is longer than conventional initiator, and it can generate two free radicals of benzoyl and phosphoryl groups after illumination. It can initiate polymerization, so the light curing speed is fast, it also has photo-bleaching effect, suitable for deep film thickening and yellowing of coating, low volatilization, suitable for water-based.This product is mostly used in white systems, and can be used in UV-curable coatings, printing inks, UV-curable adhesives, optical fiber coatings, photoresists, photopolymer plates, stereolithography resins, composite materials, dental fillers, etc.The use of this product should be based on the results of actual experiments.

The recommended addition amount is: 0.5-4% w/w.

It is fully cured on white or high titanium white pigmented surfaces.The coating does not yellow, the post-polymerization effect is low, and there is no residue.It can also be used for clear coatings and is especially suitable for products with low odor requirements.Used alone in unsaturated polyesters containing styrene systems, it has high initiation efficiency.For acrylate systems, especially colored systems, it is usually required to be used in combination with an amine or acrylamide, and compounded with other photoinitiators to achieve complete curing of the system, especially suitable for low yellowing, white systems and thick layers. Curing.Screen printing inks, lithographic inks, flexo inks, wood coatings.The recommended addition amount is 0.5-3.0% (colored system), 0.3-2.0% (transparent system).
