摘要:
A fluted filter medium to end cap bond in the production of a fluid filter is produced by 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.
摘要:
The present invention relates to an improved book-binding process comprising the use of an aqueous primer adhesive composition containing ungelatinized starch. A layer of the primer adhesive is coalesced to a resilient hinge by the application of a hot-covering adhesive without the need for an intermediate drying step. The coalesced film of primer adhesive provides a suitable underlying substrate for the adherent covering adhesive which binds the cover stock to the finished book.
