The launch took place at the Annual Conference of the International Research Group on Wood Protection (IRG WP) IRG53 conference in Slovenia, held from May 29 to June 2, 2022 in Bled, Slovenia.

Siligen MIH liq is a non-biocidal wood modification treatment designed to create more stable and durable solid woods, veneers and wood-based composites for applications such as windows, cladding, outdoor furniture, decking, in-ground platforms, parquet flooring and marine applications.

It is applied by impregnation and subsequent drying. Siligen MIH liq impregnated wood can be dried and the molecules fixed at <80°C with equipment already available at most production facilities applying conventional biocides. The energy consumption is thus similar to most aqueous biocidal wood preservative treatments.

Archcroma says that wood treated with Siligen MIH liq shows excellent protection against decay fungi and that treated wood displays improved weathering performance and keeps its natural appearance with fewer discolorations.

“Our research has been focusing for many years on the development of new wood protection systems,” said Professor Holger Militz, head of the Department of Wood Biology and Wood Products at the University of Göttingen.

“With Siligen MIH we explored a system where the wood is protected against fungi and termites without the need for complicated treatment technology. Existing vacuum and pressure plants and normal wood dryers are sufficient to use this new technology.”

“We are very excited to collaborate with like-minded partners such as the University of Goettingen,” added Miquel Vila, global head of new markets at Archroma. “The new biocide-free wood protection technology Siligen MIH liq is a great illustration of ‘The Archroma Way to a Sustainable World: Safe, efficient, enhanced, it’s our nature’.”
