In the world of professional woodworking and industrial construction, “good enough” never actually is. When you are responsible for the structural integrity of a building or the long-term durability of a high-end door, the invisible bond holding it all together is the most critical component.
This week, the industry received a significant nod of reassurance. Jowat SE, a global heavyweight in industrial adhesives, announced that it has officially secured the trusted KOMO certificate for several of its key products. For those of us in the shop or on the factory floor, this isn’t just another piece of paperwork—it’s a gold standard of reliability.
Originating from the Dutch assessment system, the KOMO quality mark is one of the most rigorous certifications in the European building sector. It doesn’t just look at the final product; it audits the technical specifications and internal quality assurance of the manufacturer.
In short: if it carries the KOMO mark, you know it’s been poked, prodded, and tested to meet the highest safety requirements.
“We are delighted with the successful certification of our products,” says Ingo Horsthemke, Vice President responsible for global marketing at Jowat SE. “This recognition is further evidence of the high quality of our adhesives and reflects our commitment to delivering verified safety and reliability.”
Jowat is no stranger to these high standards. Their Jowapur® 686.20 has held a certification for load-bearing timber parts (under directive BRL 2338) for several years. However, the latest news sees a significant expansion into non-structural applications, providing more versatility for manufacturers.
| Product Series | Certification | Application |
| Jowapur® 685.59/61 | BRL 2339 | Non-structural wood applications |
| Jowacoll® 102.27 | BRL 2339 | Non-structural wood applications |
| Jowatherm® PUR 609 Series | SKH-064 | High-performance lamination (e.g., doors) |
The Jowatherm® PUR (609.00, 609.30, 609.50, and 609.60) line is particularly noteworthy. These hot melt adhesives are now listed under the SKH quality declaration. This confirms that everything—from the chemical formulation to the production process—passes the BRL 2339 requirements.
For those specializing in door production, the Jowatherm® PUR 609.00 has already carved out a reputation as a “workhorse” adhesive. It is designed for demanding lamination processes where high initial strength is non-negotiable. Whether you are working with standard veneers or bonding metal to wood, this adhesive handles high restoring forces without flinching, ensuring the bond stays tight even under stress.
While the KOMO mark has its roots in the Netherlands, its influence is felt globally. In an increasingly regulated market, having a “verified” stamp of approval makes international trade and cross-border construction projects significantly smoother.
As Horsthemke puts it:
“For our partners in the construction sector, the KOMO certificate provides convenience and confidence—not just in the Netherlands, but across borders. Since its introduction, the KOMO certificate has earned international recognition.”
For the modern woodworker and industrial builder, this news from Detmold is a reminder that quality is a moving target—and Jowat is staying ahead of the curve. By aligning their PUR and Jowacoll lines with these strict standards, they aren’t just selling glue; they’re selling peace of mind.
