Edgebanding with PUR, Micro Emissions & EVA cartridge adhesives

Kenyon Group supplies some of the best hot melt adhesives on the market, especially when it comes to edgebanding, which has been the company’s focal point for many years.

As new products come onto the market, one adhesive range has remained unchanged, standing the test of time for good reason. 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 Holz-Her edgebanders. Having been specifically designed for Holz-Her edgebanders, they are compatible for use on all their machines with feed-rates from 10m/min.

With more and more companies choosing PURHM adhesives for the many performance benefits they provide, Technomelt Dorus HKP 27 PUR has quickly become a key choice for Holz-Her edgebanders. A go-to adhesive for kitchen, door, cubicle and bathroom furniture manufacture, it allows a high degree of moisture and heat resistance to be achieved.

Technomelt Dorus HKP 27 PUR also provides many additional benefits, such as cold flexibility resistance, high initial strength and very tight joints, which can achieve invisible glue lines.

Be kinder to the planet and switch to Micro Emissions

Technomelt Dorus HKP 29 ME – Micro emissions PUR adhesive cartridges are designed for straight edgebanding in HolzHer edgebanding machines. This product will become increasingly significant as the legislation according to REACH regarding the handling of diisocyanates is set to change on 24th August 2023. Operators using PUR Hot melts will need to be informed and trained, or may switch to Micro Emissions (ME) PUR. 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 HKP 20 and Technomelt Dorus HKP 25. Between these two all the bases are covered, helping achieve the production line finishes that are expected in today’s competitive markets. Technomelt Dorus HKP 20 is an unfilled, transparent, EVA edgebanding hotmelt for Holz-Her equipment. Allowing for thinner coat weights and high glue mileage, it is a premium EVA grade.

Technomelt Dorus HKP 25, meanwhile, 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 is selected, you can be assured that the adhesive options available will have it covered.

Another product of note is the Technomelt Cleaner 2 – a blue cleaning agent for all polyurethane (PUR) hotmelts in an 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 innovative addition provides companies access to other highperformance 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. Whatever the machine, Kenyon Group has a glue to match.

The Henkel name is quite rightly associated with quality and market leading technologies, and this does not purely apply to the company’s adhesives, but also to its extensive range of hot melt 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 has the expertise to boost productivity.

PUR adhesives and good house keeping

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 offer 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’s is proud to be Henkel premium partners, covering furniture and building components.
