  • Bonded fluted filter media to end cap
    Patent number: 4890444
    Abstract: A fluted filter media to end cap bonding process and fluid filters formed by the bonding process. The process comprises coating at least one end cap and/or at least one fluted edge of the filter media with a bonding composition, contacting the end cap with the edge of the fluted filter media and curing the bonding composition coating to form a strong, continuous filter media to end cap bond. The bonding composition comprises, in adhesive latex, a thermoplastic resin and an amount of ungelatinized granular starch effective to complex a major portion of the latex water during curing of the bonding composition.
