  • Pressure sensitive adhesive tapes from cationic cure adhesives
    Patent number: 7521116
    Abstract: Pressure sensitive adhesive tapes produced by a process where cationic cure is conducted against a paper film substrate and an optional second film substrate, both having low moisture content. The low moisture content is maintained during cationic cure by putting the pressure sensitive adhesive tapes in an environment where moisture ingress is prevented. The maintenance of low moisture during cure provides enhanced SAFT values.
