Properties and Usage:

Photoinitiator 819 is an efficient and universal UV photoinitiator with excellent curing effect and anti-yellowing properties. Initiates free radical UV polymerization of unsaturated resins under ultraviolet and near-visible light irradiation.

Increase the corresponding weather resistance of UV-cured coatings, optimize the coating curing effect and resist UV yellowing.

Performs well in deep cure curing systems. Therefore, it is more suitable for curing systems such as metals, plastics, and inks.

Different formulas and mixtures with other photoinitiators have more different curing effects and luminosity effects. Please ask our team for details.

Storage and transportation:

Store in a cool, dry warehouse. Keep away from sparks and heat sources. Avoid direct contact with skin.

Packaging specifications:

20KG/drum, or customized packaging according to customer requirements.
