K-PURE TAG-2678

K-PURE TAG-2678 is a quaternary ammonium blocked triflic acid thermal acid generator specifically designed for use in thermally cured microlithography coatings. It has a sharp and irreversible activation profile and does not produce any volatile components upon activation. K-PURE TAG-2678 is ideally suited for amino crosslinkable (melamine, self-condensed melamine, glycoluril, urea) or silanol and alkoxysilane crosslinkable resins. K-PURE TAG-2678 can also be used to catalyze the polymerization of epoxy resins and ring opening polymerization of cyclic ethers as well as other monomers capable of undergoing cationic polymerization.
