Title: Thomas G. Swift and Vegetable-Based Adhesive Innovations
Introduction
Thomas G. Swift was an inventor associated with Decatur, Illinois, and A. E. Staley Manufacturing Company. His work focused on improving remoistenable adhesives used on pregummed tape. He is credited with 2 patents.
Latest Patents
Swift’s listed patents explore modified starch formulations designed to replace some or all of the animal glue traditionally used in pregummed tape adhesives.
“Vegetable Based, Remoistenable Adhesive for Pregummed Tape” describes adhesive compositions made with a low-viscosity starch-acrylamide graft copolymer in an aqueous medium. The formulation was developed for use on pregummed substrates.
“Pregummed Remoistenable Tape Having Long Open Time and Short Tack Time” describes tape adhesives based on acid-hydrolyzed, modified waxy maize starch. The disclosed approaches include starch copolymerized with acrylamide and acid-hydrolyzed, cyanoethylated starch. The patent also discusses replacing substantial amounts of animal glue, or—in certain applications—nearly all of it, with synthetic compounds such as polyvinyl alcohol.
The formulations were intended to maintain or improve wet tack while offering practical benefits such as better machinability, reduced odor, easier remoistenability in cold conditions, and improved aging performance. Among the modified starches tested, the acid-hydrolyzed, cyanoethylated starch and acid-hydrolyzed acrylamide-starch graft copolymers performed particularly well, especially when combined with small amounts of animal glue.
Career Highlights
Swift’s patent work addressed a specific materials challenge: developing effective alternatives to animal-glue adhesives for remoistenable tape. His inventions applied modified starch chemistry to improve adhesive performance and manufacturing characteristics.
Collaborations
Swift was associated with A. E. Staley Manufacturing Company. His listed coworker was William A. Bomball.
Conclusion
Thomas G. Swift’s patents document efforts to create starch-based remoistenable adhesives that could reduce reliance on animal glue while supporting the performance and production needs of pregummed tape.
