Quality Assessment


The “Quality Assessment” department focuses on projects concerning formaldehyde testing methods as well as bonding, bonded joints and adhesives for products using and made from renewable raw materials. Within an interdisciplinary team, we develop solutions for and with customers from, amongst others, the forestry and timber, construction, furniture and chemical industries

In certified further training courses at our WKI | AKADEMIE®, we make available the expertise which we have gained from the contact to manufacturers and through our research work. Our department is furthermore internationally recognized as a testing, monitoring and certification body and is therefore a competent contact partner for all questions relating to TMC.
