National Adhesives, Bridgewater, N.J., published a flyer featuring new VECTORPATCH window adhesives, a window gum family that provides both machine speed and gum box stability necessary to work on all envelope folding machines. Historically, envelope converters have had to compromise between the tack needed for high-speed machines and the gum box stability needed on slower equipment. Now, VECTORPATCH window gums solve this dilemma by delivering outstanding performance on a wide range of envelope folding machines—at a broad range of speeds and on a variety of papers. Specifically, VECTORPATCH adhesives provide high tack on the fastest folding equipment; gum box stability, resulting in minimal buildup

National Adhesives, Bridgewater, N.J., published a selector guide featuring DURO-TAK hot-melt pressure-sensitive adhesives (PSAs). The high-performance adhesives are designed to optimize coater line speed in labeling and other applications requiring high tack. Information provided in the full-color, eight-page “DURO-TAK Hot Melt PSAs Selector Guide” allows applicators to choose the right combination of properties and end-use performance. Physical properties and performance data for 13 DURO-TAK products—with information about viscosity, softening point, Gardner color, special features, peel, shear and typical applications—are provided in two detailed charts.

A technical paper on new high-performance UV-curable acrylic hot-melt, pressure-sensitive adhesives (PSAs) is available from National Adhesives, Bridgewater, N.J. The paper, by Dr. Graeme A. Roan of National Adhesives, explains why the adhesives represent the next generation of high performance PSAs, and how they provide a genuine, technically and commercially viable alternative to solvented PSAs in industrial tape applications. The adhesives can be cured efficiently with relatively low doses of UV light, giving rise to reliable, reproducible performance tapes with excellent depth of cure across the range of industrial tapes. Dr. Roan has worked in the acrylics business in both the United States and Europe, and

National Adhesives, Bridgewater, N.J., introduced EASY-PAC C, the lowest temperature freezer-grade case and carton sealing hot-melt adhesive available on the market. EASY-PAC C has an operating temperature range of 212 to 225 F, and adheres at temperatures of -20 F and potentially lower depending on the substrate. The adhesive is already being used successfully by manufacturers and packagers of consumer ice cream, dairy and poultry products. EASY-PAC C is only sold with the EASY-PAC Package Sealing Solution, a complete system that National Adhesives has developed for case and carton sealing applications in food processing, beverage, personal care, household, industrial-goods and consumer electronics industries. The EASY-PAC

A technical paper on new high-performance, UV-curable acrylic hot melt pressure-sensitive adhesives (PSAs) will be presented at the Tech 30 Global Conference VI in Orlando, Fla., May 14 to 16, by Dr. Graeme A. Roan of National Adhesives, Bridgewater, N.J. The paper will explain why the adhesives represent the next generation of high-performance PSAs, and how they provide a genuine, technically and commercially viable alternative to solvent-containing PSAs in industrial tape applications. The adhesives can be cured efficiently with relatively low doses of UV light, giving rise to reliable, reproducible performance tapes with excellent depth of cure across the range of industrial tapes.

“The New Gum Gazette,” a free newsletter for envelope manufacturers from National Adhesives, Bridgewater, N.J., offers tips for improved envelope productivity and aesthetics. Topics include boosting tack with remoistening aids, showing how paper grain direction impacts adhesive performance, improving gum seal appearance and avoiding problems with “timed” or “drop seal” gumming methods. The newsletter features a chart comparing the fiber-tear speeds of remoistening solutions supplied by major adhesives producers, a problem/solution chart for gum seal appearance and a graph illustrating how viscosity impacts gum box stability. National Adhesives—a unit of National Starch and Chemical Company—provides hot-melt, liquid emulsion and solvent-borne solution adhesives worldwide. The

If the Wizard of Oz was granting a distributor’s wish for increased sales success, he just might produce an array of labels, decals and tags from his bag of tricks. Nothing can compete for customer loyalty while effectively differentiating brand identity and providing content information quite like a label. And, given the adhesives discoveries, design innovations and aesthetically appealing substrates, they thrive on technology and marketplace challenges. Adhesives are certainly playing a role in creating label products and opening new markets. Ingrid Brase, global marketing manager for National Adhesives, pointed out utilizing clear film for a no-label-look is replacing the much more expensive process

National Adhesives, Bridgewater, N.J., offers a free, eight-page brochure providing a summary of various types of adhesives and gums used in envelope manufacturing. “Envelope Adhesives 101” contains information on the five most common adhesives used in envelope production, as well as specialty adhesives for applications such as X-ray film storage envelopes, archival envelopes and translucent-paper stocks. Adhesive formulation data, a coating-weight chart for various paper stocks and a chart detailing adhesive characteristics—such as thickness, adhesion, humidity, resistance, tack and appearance—are provided. Featuring illustrations and photographs of various envelope types, the brochure also explains the best practices for handling and storing finished products. In other

Key variables affecting quality and consistency in rotary side-seam gumming are addressed in a new, complimentary four-page color brochure from National Adhesives, Bridgewater, N.J. The brochure explains how to avoid problems by focusing on the gum’s formulation and viscosity, various factors of the gumming machine and steady supply to the gum box. For the most effective operation, the rotary side-seam gum must retain moisture and minimize foaming. The brochure identifies the specific formulation that meets these requirements. The gum also must feature an ideal viscosity measurement—defined in the publication, along with suggestions for diluting. The brochure provides details on gum box condition, roller

Key variables affecting quality and consistency in rotary side-seam gumming are addressed in a new, complimentary four-page color brochure from National Adhesives, Bridgewater, N.J.
