日本化药株式会社生产的光重合开始剂・促进剂重一种高效紫外光（UV）引发剂，属于 α- 氨基酮类光引发剂。

basic features

chemical type: α-amino ketone derivatives, which are commonly used free radical-type UV photoinitiators, which can decompose and produce free radicals under ultraviolet light irradiation, triggering polymerization reactions of unsaturated monomers or prepolymers such as acrylates.

absorption wavelength: The main absorption wavelength range is about 250-380nm, and it has a good response to both medium-wave ultraviolet (UV-B) and long-wave ultraviolet (UV-A), making it suitable for a variety of UV curing systems.

initiation efficiency: It has high photoinitiation activity, which can effectively promote the curing reaction even at low dosages, especially in thick coatings or colored systems, which can reduce the effect of oxygen inhibition.

compatibility: Good compatibility with most acrylate monomers, prepolymers (such as epoxy acrylates, polyurethane acrylates) and solvents, and is not prone to precipitation or delamination, making it easy to formulate.

application area

is widely used in fields requiring rapid photocuring as a highly effective UV initiator:

UV coatings: such as wood coatings, plastic coatings, metal coatings, etc., promote the rapid curing of coatings and improve production efficiency.

UV inks: Printing inks suitable for substrates such as paper, plastic film, and metal foil, accelerating curing and ensuring scratch resistance and adhesion of prints.

Light-curing adhesives: Used for bonding optical components, electronic components, etc., ensuring rapid high-strength bonds under UV exposure.

Use & Store

Addition: 0.5%-3% (mass fraction) is usually added to the formula, which needs to be adjusted according to system activity, curing thickness, and light source intensity.

storage conditions: need to be protected from light, sealed and stored in a cool and dry place, avoid high temperature and direct sunlight, and prevent premature decomposition and failure.

safety: avoid direct contact with skin and eyes during operation, and it is recommended to wear protective equipment; It is a flammable substance and needs to be kept away from the source of fire.
