Jowat unveils new adhesives for glulam

Jowat has achieved assembly-pressing time ratio of up to 1:1, which has sparked a lot of interest among customers with industrial manufacturing processes.

The adhesives manufacturer from Detmold (Germany) again impressed customers and prospects alike with its latest and innovative product highlights at this year’s leading global trade fairs, Ligna and Interzum.

The spotlight was on non-hazardous PUR hot-melt adhesives, a fully certified product family for load-bearing glulam, as well as on new dispersion adhesives with low formaldehyde emissions.

The adhesives specialist displayed a comprehensive portfolio of monomer-reduced and therefore non-hazardous reactive polyurethane (PUR) hot-melts for the wood and furniture industry from the Jowatherm-Reaktant MR series, once more demonstrating the enterprise’s innovative capacity and competence in PUR technology.

The special highlight of the non-hazardous product series presented by Jowat at the trade fair was an unfilled edge banding adhesive for superior applications, which facilitates colourless and virtually invisible bond lines.

Reactive PUR hot-melts were also in the spotlight at Interzum, with focus on the significant process and efficiency benefits compared to liquid adhesive systems in the manufacture of mattresses and upholstered furniture.

The new Jowapur product family for load-bearing glulam also proved a major success. For the first time, the adhesives experts from Detmold presented an expanded portfolio of certified 1-component PUR pre-polymer adhesives, with different product versions for a wide range of applications in the manufacturing of load-bearing glulam.

The previously unachieved assembly-pressing time ratio of up to 1:1 and flexible assembly times between 10 and 60 minutes, in particular, sparked a lot of interest among customers with industrial manufacturing processes in which short cycle times and fast throughput speeds are essential.

Another technological first at Ligna were the dispersion adhesives from the Jowacoll series. Due to an optimised manufacturing process, Jowat was able to reduce the formaldehyde content in the Jowacoll dispersions by up to 80% and at the same time maintain the good water and heat resistance of the adhesives.

As a result, formaldehyde emissions from Jowat’s reactive D3 dispersions are now below the limits defined in different regulations and in some cases even close to the detection limit, and therefore support the production of low-emission products.
