Over the last few years, there has been much publicity about which hotmelt adhesive to use for edgebanding and edge lipping for the bonding of various materials to wood-based panel products. Kenyon Group’s Technical Sales & UK Sales Manager, Steve Morrow, tells us more ...
“It’s universally accepted that Henkel Technomelt EVA-based adhesives are straightforward to use and process,” he says. “Technomelt EVA-based adhesives are still as popular as ever, and Henkel offers a full range from filled to unfilled to suit every application. However, EVA-based adhesives are not ideal if the finished product is likely to be subjected to steam, heat or moisture.
“An alternative to Technomelt EVA-based adhesives is Henkel Technomelt PUR adhesives, which dominate the edgebanding market. Over the years, PUR adhesives have been more accessible to customers who are edging, and as technologies advance, PUR adhesives’ outstanding performance has become available to all edging customers, delivering the finished goods to the highest standards. If joints need exceptional water or heat resistance, then PUR adhesives are recommended, as they have a significantly superior performance versus an EVA adhesive.
“An additional string on the bow for Henkel Technomelt PUR adhesives is that they are leading the way in micro emission technology with Henkel Technomelt Micro Emissions PUR adhesives. These adhesives offer the same performance benefits that come with PUR technologies: low coat weight, tight joints, invisible glue lines, and exceptional high performance, all combined with excellent heat and water resistance, but without the hazardous labelling, making it more environmentally friendly and safer for operators to handle.
“Henkel Technomelt Polyolefin based hot melt adhesive bridges the gap between EVA and PUR by offering higher heat resistance and higher performance than an EVA, but with similar pricing levels.
“TECHNOMELT Polyolefin adhesives offer benefits of ultra-thin glue lines for superior edge aesthetics on all board types & colours, and are clean running adhesives with no stringing, which leads to less downtime for maintenance and cleaning. This, in turn, leads to increased production. Technomelt Polyolefin adhesives can reduce your glue usage by up to 20% as they have increased performance, and, therefore, the coat weight per linear metre can be reduced. This can lead to cost savings.
“As new products come onto the market, one adhesive range has remained unchanged, standing the test of time and for good reasons. Offering both EVA and PUR technologies, Henkel’s Technomelt DORUS HKP range of hot melt adhesive cartridges provides exceptional gluing performance and an easy-to-use option for HOLZHER edge banders. Having been specifically designed for HOLZHER edge banders, they are compatible for use on all their machines. HOLZHER edge banders are not just limited to cartridge adhesives. With clever additions such as the hopper system, which can be attached to the machines, it allows for the use of both Henkel Technomelt EVA and PUR granule adhesives.
“So, you’re running Henkel PUR, Polyolefin or EVA hot melt adhesives for edge banding or edge lipping and therefore already recognise and demand the highest quality and performance from your adhesive. To ensure optimum performance, the same quality cleaner should be sought. Sadly, sometimes overlooked, cleaners play a vital role in your day-to-day operations – many would argue just as crucial a role as the adhesive itself – a good cleaner can make all the difference. And the Henkel name is quite rightly associated with quality adhesives as well as hot melt cleaners, with their extensive range, which covers everything from surface cleaning to thorough system/application equipment cleaning. The right Henkel cleaner will bring you many operational benefits, ensuring consistent dispensing & bond quality, reducing downtime & maintenance, as well as prolonging the lifespan of application equipment.
“However, it’s not just the adhesives and cleaners that make Henkel adhesives the market leaders; it’s the technical and onsite support offered by both Henkel and Kenyon’s that separates us from the rest of the field. We don’t just sell adhesives; we live them, and this includes supporting you! Remember, there are edgebanding adhesives and cleaners, and then there’s Henkel’s next generation of edgebanding adhesives and cleaners – it’s really that simple. Henkel Technomelt range are superior products at the right price with proven results – just ask anyone using Henkel edgebanding adhesives!” Steve concludes.
