Non-yellowing Cationic Thermal Initiator

CTI-100 and CTI-150 are blocked sulfonium antimonate cationic initiators with low deblocking temperature and high curing reaction activity for epoxy compounds, but have excellent storage stability. It is especially suitable for systems such as alicyclic epoxy and oxetane that are not suitable for amine curing agents. Or as an effective supplement to photo-curing initiators, it can be used as a dual-cure application in dark conditions or extremely thick coatings. In industries such as electronic packaging, 3D printing , 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. The cured film will not yellow, have no free acid residue, and is stable in storage.

Non-yellowing cationic thermal initiators are very useful in applications that require high-temperature curing or thermal cross-linking, such as high-temperature baked inks, coatings, adhesives, composite materials, etc. The selection of these initiators usually depends on the specific application requirements and materials used to ensure that the material retains its original color and transparency under high temperature conditions.

Non-yellowing cationic thermal initiator

In order to ensure the safety and integrity of our products during transportation, we use high-quality iron drums for packaging. Iron drum packaging is strong and durable, which can effectively protect products from the external environment and ensure that products remain in the best condition during transportation. 

F: What are the precautions for this product?

Q: The dosage should be appropriate, not too much or too little. If it is too much, the reaction speed will be too fast and difficult to control. If it is too little, it will be difficult to initiate, and the reaction will not proceed normally, affecting the polymer properties. The dosage is generally about 1%-2%.
