AA-01Thermal acid generator (thermal cationic polymerization initiator), ammonium

Characteristics and Applications

AA-01 is a highly active heat-activated acid generator of the ammonium salt type. Because it uses a borate anion, it is non-Sb, but it has the same acid strength as SbF6 anion products and shows high cation polymerization. It also has excellent low metal corrosion of the cured product.

Polymerization initiation temperature

When combined with bisphenol A glycidyl ether, polymerization begins at 100℃, and when combined with alicyclic epoxy, polymerization begins at 74℃.
Characteristics of the generated acid [HB(C6F5)4]

It has a high acid strength and is as reactive as HSbF6. It also prevents corrosion of surrounding metal parts because it is not easily hydrolyzed and does not easily produce hydrofluoric acid.
Recommended amount of additive

Add 0.5 to 1 wt% to the resin, depending on the application, film thickness, and temperature.
