SpeedTeCC

In cooperation with the Institute of Joining and Welding Techniques (TU Braunschweig) and the department for Timber Structures and Building Rehabilitation (University of Kassel), we are developing procedures and technologies for the quick and simple production of high-quality wood-concrete composite elements through application of an innovative rapid-bonding technique.

Additional benefits of “NawaRo” insulation materials

Under the leadership of the Fraunhofer WKI, a consortium of twelve research institutes is conducting interdisciplinary research into holistic solutions in order to significantly increase the application of insulation materials made from renewable raw materials (German: nachwachsende Rohstoffe, “NawaRo”).

Low-formaldehyde dispersion adhesives

For the manufacture of wood-based products, aminoplastic resins containing formaldehyde are primarily used as binding agents. The goal of this project is the development of an alternative in the form of an innovative low-formaldehyde dispersion adhesive for the production of wood-based materials on the basis of polyvinyl acetate (PVAc) with radical polymerizable sugar derivatives.

EcoPressWood

Pressed wood panels are composed of chopped or cut wood that is glued together using adhesives. Most of these resins are petroleum based products containing a hazardous chemical: formaldehyde. The acceptable levels of formaldehyde in wood pressed products have been reduced over the past decades due to increased public awareness on its effects on health and the consequent consumer demand for non-hazardous products. We are developing a formaldehyde-free thermo-setting bio-based resin (pre-polymer) for wood-based panels.

Isocyanate reactivity in wood bonding

Due to the current debate concerning the emissions of formaldehyde from wood-based materials, an enhanced potential for isocyanates as cross-linking adhesive components can be seen. The application of isocyanates in wood bonding may not, however, be regarded as trivial. We are developing an analytical method which will enable us to follow and evaluate the isocyanate reactivity.

OptiGas 2020

We are revising the procedure for the determination of formaldehyde release in accordance with the gas analysis method ISO 12460-3. In addition to a shortening of the testing time and an optimization of the analytics, the focus of the research work is also being placed upon the applicability of the gas analysis method to other wood-based materials as well as the implementation of the findings in standardization procedures.
