Adhesives
Edgebanding with PUR and EVA cartridge adhesives
Kenyon Group supplies some of the best hot melt adhesives on the market, especially when it come to edgebanding, which has been its focus point for many years.
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 hotmelt adhesive cartridges provides exceptional gluing performance and an easy-to-use option for Holz-Her edgebanders. Having been specifically designed for Holz-Her edgebanders, they are compatible for use on all these machines with feed-rates from 10m/min.
With more and more companies choosing PURHM adhesives for the many performance benefits they provide, Technomelt Dorus HKP27 PUR has quickly become a key choice for Holz-Her edgebanders, making it the go-to adhesive for kitchen, door, cubicle and bathroom furniture manufacture, allowing a high degree of moisture and heat resistance to be achieved. Technomelt Dorus HKP27 PUR also provides many additional benefits such as cold flexibility resistance, high initial strength and very tight joints, which can achieve invisible glue lines.
Technomelt Dorus HKP 20 and 25 Henkel Technomelt 270/7 PUR granules
Where high moisture or heat resistance is not required, for example in bedroom furniture, EVA adhesives are the ideal choice for companies. The Technomelt Dorus HKP range has an exceptional offering, with Technomelt Dorus HKP20 and Technomelt Dorus HKP25 – between these two all the bases are covered, helping achieve the production line finishes that are expected in today’s competitive markets.
There is Technomelt Dorus HKP 20, an unfilled, transparent, EVA edgebanding hotmelt for HolzHer equipment allowing for thinner coat weights and high glue mileage, making this a premium EVA grade.
Technomelt Dorus HKP 25 is a filled EVA edgebanding hotmelt for Holz-Her equipment, available in a range of colours (natural, white, brown and black), so no matter what edging colour has been decided upon, the adhesive options available will have it covered.
Then there is Technomelt Cleaner 2, a blue cleaning agent for all polyurethane (PUR) hotmelts in the uncured state.
Holz-Her edgebanders 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 EVA and PUR granules. This clever and innovative addition provides companies access to other high-performance grades from the range, such as Technomelt Dorus KS 351 unfilled edgebanding or Technomelt PUR 270/7 G (granules), both of which are recognised for their clean running and outstanding gluing performance.
The Henkel name is quite rightly associated with quality and market-leading technologies, and this does not purely apply to its adhesives, but also to its extensive range of hotmelt cleaners, which cover everything from surface cleaning through to thorough system/application equipment cleaning. Given that an effective cleaning process can make all the difference to meeting deadlines, maximising output and achieving daily goals, Kenyon Group is here to help set users on the right path and ensure they are getting the most out of their day.
Having recognised the gap in the market, Henkel made the decision to manufacture its Premium PUR grade – the tried, tested and proven Technomelt 270/7 – in a granular form, allowing companies to run the PUR adhesive on their existing edgebanding lines without the outlay and hassle of purchasing new equipment. This has proved very successful, providing easy access to PUR technology for every company, opening the door to what can be achieved with PUR and increasing the quality of the finished goods.
Henkel PUR granules make gluing easy, with their ability to be used on customers’ existing edgebanding lines – convenient, flexible, and providing cost-saving advantages. Technomelt PUR 270/7 is supplied in 12kg cartons, with each carton containing 16 x 750g individual foil packs of PUR granules. This provides a cost-effective option for middle-to-low volume users, by allowing them to control the amount of adhesive being used against their scheduled volume of work. Foil packs that have been opened can be wrapped and taped and will be good for around 48 hours, reducing wastage and saving money.
PUR adhesives and good housekeeping
When it comes to cleaning, as with any PUR adhesive, a wax-based cleaner such as Technomelt Cleaner 2 is required to prevent the adhesive from cross-linking and curing within the machine. With the larger 2kg blocks, normally one or two cleaning slugs will have to be purged through the system, to clean it down of any remaining PUR within it.
Henkel’s PUR granules provide users with the ability to gauge the adhesive level within the glue pot throughout the day and run it down towards the end of the shift, meaning there is very little PUR adhesive left in the glue pot prior to cleaning. Use the recommended cleaner for Henkel PUR granules (Technomelt Cleaner 4), which is supplied in a blue granule form, and can be put directly into the glue pot. Normally, half to a full cup will be sufficient. This reduces cleaning times and allows for a quick start-up the following morning.
Kenyon is proud to be a Henkel Premium Partner, covering furniture and building components.

You can keep calm … if you are a Taka customer
In case you did not now, the main raw materials for HMPUR (reactive polyurethane) adhesives are mainly polyesters and isocyanate. Polyesters are the main ingredient that gives the adhesive their essential characteristics such as initial bond strength, open time, resistance to weathering conditions and viscosity, as well as the melting and application temperature.
Taka’s in-house production of polyesters is therefore a strategic and extremely valuable capability in today’s unsettled market, and therefore a good choice to customers for several reasons – first, to ensure the high performance of the adhesive, then to ensure stability, quality, and tolerance of each batch. This allows Taka to give an immediate response in the development of new adhesives with tailor-made characteristics for individual customers.
Finally, this allows Taka to thrive through times of limited availability of raw materials while most of the market fights for the raw materials that are left. Taka’s customers have better continuity of supply and can concentrate on their business knowing they are being taken care of with their adhesive needs.
From the very beginning of Taka’s production, the business made a strategic choice to manufacture its own raw materials (polyesters), by immediately creating plants dedicated to the production of basic polyesters used in the production of polyurethane hotmelts.
Taka’s vision has proved particularly useful at this time, when the building and furniture markets are experiencing unprecedented increases in demands for adhesives, timber, plastics, etc. Taka has stock raw materials to serve its current customer base, and can even increase it further.
Thanks to Taka’s strategic choices and the investments that Taka has made and will continue to make, it is able to maintain constant production and supply of its products to customers all over the world, without exception.
Taka says that particular attention is paid to the UK market, which has always been an extremely important one. Taka has already been present within the UPVc industry for 15 years and boasts considerable market share thanks to Mike Dean at Adhesive Solutions. Taka is steadily growing the woodworking/furniture market thanks to its co-operation with Brit-Ad, and has two distribution warehouses to cover both of these important industries. Taka also has a UK-based technician for the installation of machinery and application of the adhesives, who has 30 years’ experience within the profile-wrapping industry.
Free from the worries of production, Taka can concentrate on the research and development of new adhesives, new solutions, and technical application advice. Taka always remains close to the customer, to improve processes and satisfy requests for the development of customised products.

Ostermann on glue applicators – useful tools for gluing and bonding
To build or repair furniture, you need white glue. For a pinpoint application and the right dosing, carpenters/cabinetmakers will find at Ostermann not only a wide range of glues, but also glue applicators for a variety of uses.
The application devices are as varied as the applications of dispersion adhesives. Since it is critical with glue to keep it from unwanted curing, many of these tools also include a storage function. Besides glues and adhesives, Ostermann supplies useful accessories. For further information, type in the search item “#glueapplication” on the Ostermann website www.ostermann.eu
Ostermann provides the industry with many useful tools for a clean and economical glue application. Here you can see an application of the popular Pfohl glue applicator
INVENTIVE TOOLS FOR A PINPOINT APPLICATION
For small-scale applications, there are glue bottles with a pointed nozzle that can be flexibly shortened. A variety of additionally available pointed, wide and dowel nozzles can be used for particularly precise applications. To store the bench glue, Ostermann suggests using the Pfohl GluePort.
It offers a proper place for the glue bottle and keeps the glue from drying out. The climate container of the GluePort is filled with 150ml of water and conveys humidity to the glue tip via a foam inlay. Even slightly dried-out tips will open up again after some time in the port.
LARGE-SCALE APPLICATIONS – ECONOMICAL AND EASY
The glue applicator from Pfohl has proven a useful asset for larger surfaces. The sturdy hand tool has an integrated glue container from which the liquid glue is applied to the workpiece via an exchangeable roller. The tool is supplied with a stand and a rubber roller, and available in different widths. If you want to apply the glue to uneven or highly absorbent surfaces, it is best to use the Pfohl glue spreader. It has two differently serrated sides and an integrated glue container. Pfohl’s Leimfix is made for an even, edge-defining application of glue onto wooden surfaces with widths of up to 140mm. To do so, the workpiece is pushed over the upper application roller of the box.
ALWAYS THE RIGHT ADHESIVE
As an edging specialist and carpentry partner, Ostermann provides glues and adhesives for a wide range of applications and surfaces, and from many established brands. The products from Ostermann’s own brand REDOCOL are particularly popular. You will find these in the online shop, together with detailed product information. For more information on dispersion glues as well as other types of adhesives, you can also visit Ostermann’s Product Groups.
KEEP THE BEST FOR LAST
To make it easier to fill glue from a bucket into the different applicators, use the Easy-Pump glue pump. The hand pump facilitates a clean and easy extraction or transfer of glues and lacquers. You can operate the pump manually via the crank handle, or you can use an electric screwdriver. The spouts can be shortened individually.
