What can I do for you?
Photoinitiators are compounds that absorb light energy and produce free radicals, which are commonly used in photochemical reactions. Their role is to initiate or accelerate chemical reactions under the action of light, so as to achieve efficient and fast chemical reactions.
Photoinitiator TPO is a highly efficient free radical (1) type, highly efficient photoinitiator with absorption in the long wavelength range. Because of its wide absorption range, its effective absorption peak of 350 ~ 400nm, has been absorbed to about 420nm, its absorption peak is longer than conventional initiators, by light can generate benzoyl and phosphoryl two radicals, both can trigger polymerization, so the light curing speed, it also has a photobleaching effect, suitable for thick film...
Tpo-l is a highly efficient free radical (I) type liquid photoinitiator, mainly used for UV curing of corresponding resins, such as unsaturated acrylates. Especially used in white system and thick film UV curing; Very fast curing photoinitiator; Tpo-l is a liquid photoinitiator, suitable for formulation system with low yellowing and low odor. Because TPO-L has a wide range of absorption can also be used for curing containing white paint. To improve the curing effect of the surface, tpo-l is...
2-Methyl-4'-(Methylthio)-2-Morpholinopropiophenone is an efficient UV photoinitiator for initiating UV polymerization of unsaturated prepolymer systems, Such as acrylic resins and monofunctional and multifunctional vinyl monomers. The initiator molecule has a certain light absorption capacity in the ultraviolet region (250-400 nm) or the visible region (400-800 nm). Application: Used as an initiator in a photo-curable material UV-curable coatings and inks Highly efficient photoinitiator can be...
2-Isopropylthioxanthone is light yellow solid Uses A thioxanthone derivative useful as photoinitiators. 2-Isopropylthioxanthone is a thioxanthone derivative useful as photoinitiators.
Light curing system including UVG, UV coating, UV ink, etc., accept or absorb the external energy, itself will occur chemical changes, decomposition into cations, causing polymerization and reaction. All substances that produce free radicals by...
What are the characteristics of the photoinitiator TPO? The ideal photoinitiator TPO should have the following advantages: (1) Cheap, simple synthesis. (2) The photoinitiator and its photolysis products should be non-toxic. (3) Good stability, easy...
The appropriate photoinitiator TPO was selected according to the type of prepolymer and monomer And it has good solubility and reactivity. Consumption. The advantages of high efficiency. It needs to have some thermal stability. Below 85 does not...
