Thermal Initiator
Blocked phosphate cationic thermal initiator, especially used in alicyclic epoxy, oxetane and other systems that are not suitable for amine curing agents, or as an effective supplement to photocuring initiators, in dark conditions or extremely thick The film is applied as a dual cure. In industries such as electronic packaging, 3D printing, material bonding, and epoxy composite molding, it is used as a cross-linking agent in the post-curing reaction to make the final curing of the main resin more complete.

do you have any question?
What are the most common and practical cationic photoinitiators?
Uyracure-180 is the company's most commonly used initiator, suitable for mercury lamp curing. It can be cured under LED light source when used with photosensitizer. It is colorless and transparent, has no odor after reaction, and does not migrate.
What should I choose if I want to illuminate at 405nm or higher wavelength?
We have excellent photosensitizers that can be used with photoinitiators to cure at higher wavelengths
Are there any special cationic photoinitiators?
Our Uyracure-2500L is an initiator with excellent photosensitivity. It has outstanding performance in acid production activity and long-wave absorption under different light sources. The cured coating does not turn yellow, does not release benzene, and has good compatibility.
What are the reasons that you Cannot use end mill as a drill?
The cutting surfaces on a vertical end mill bit (are for milling ) are on its sides , designed for cutting horizontally , a drill bit ( are for drilling ) cutting surface is at its tip , designed for cutting vertically downward .. you'll notice a end mill usually has a flat on the end of the bit .
Where can cationic thermal initiators be used?
Cationic thermal initiators can be used in systems that are not suitable for amine curing agents, such as alicyclic epoxy and oxetane, or can be used with photocuring initiators for dual curing applications. Our CTI-100 is a cost-effective cationic thermal initiator that does not yellow and is storage stable.
What if I need low energy curing?
Our Uyracure-500 can be cured quickly under low LED energy, has good surface drying, slight yellowing, and is suitable for white inks and transparent coatings. Our long-wave initiator is very suitable for applications with high environmental requirements.
Benefits of Cationic initiator
Cationic photoinitiators are another very important type of photoinitiator reagents. Their basic action characteristic is that light activates the molecules to an excited state, and the molecules undergo a series of decomposition reactions, ultimately producing super strong proton acids (also called Bronsted acids), which act as active species for cationic polymerization and initiate polymerization of epoxy compounds, vinyl ethers, lactones, acetals, cyclic ethers, etc.
Efficiency
Only a small amount of initiator is needed to make the reaction proceed.
High reactivity
Cationic initiators mainly react with charge transfer and ionization, and have high reactivity
High photosensitivity
Cationic initiators are usually faster than free radical initiators.
Selectivity
Cationic polymerization initiators have different selectivities for different types of monomers, thereby controlling the rate of the polymerization reaction.
