Application:
- It is mainly used in white system, and can be used in UV curing coating, ink, UV curing adhesive, optical fiber coating, photoresist, photopolymer printing plate, stereolithography resin, composite materials, dental fillings, etc.
- Photoinitiator is mainly used for screen printing ink, lithography ink, flexo printing ink and wood coating. TPO can be completely cured on the colored surface of white or high titanium dioxide. It is widely used in various coatings. Because of its good adsorption, it is especially suitable for screen printing inks, lithography, flexo printing inks and wood coatings. The coating will not turn yellow, the post polymerization effect is low, and there is no residue. It can also be used for transparent coatings, especially for products with low odor requirements.
Storage:
Keep the seal and keep it under low temperature and dry condition.
