WISA BioBond
 

WISA® BioBond replaces a minimum of 50% of the fossil-based phenol in WISA plywood products’ glue with bio-based lignin: the tree’s own natural adhesive. WISA-Spruce plywood with WISA BioBond technology is an excellent material for specifiers targeting a reduction in embodied carbon emissions.

WISA BioBond is incorporated in all WISA-Spruce plywood products and some WISA-Birch products. It will gradually replace fossil-based phenol in all WISA plywood products. The innovation takes us another step closer to the ultimate goal of a construction material with zero fossil-based materials.

 

Replacing fossils

The key ingredients for WISA plywood products – wood and glue – now originate in the same place: responsibly managed forests.

Low chemical emissions

The new bonding technology makes WISA especially attractive for construction and indoor work and living environments where low emissions are important.

Outstanding performance

WISA plywood manufactured with the new lignin-based WISA BioBond bonding solution meets all the technical performance requirements for industrial-use plywood.

 

What is lignin?

Lignin is a class of complex organic polymers that form important structural materials in the support tissues of vascular plants and some algae. Lignin is present for example in trees as the internal “glue” filling the spaces in the cell wall between cellulose, hemicellulose, and pectin components. Chemically, lignins are cross-linked phenolic polymers.

How WISA BioBond is born

The story of the new bio-based bonding solution starts in responsibly managed forests. The process is a good example of UPM’s Biofore thinking which emphasizes resource efficiency and the innovative use of production residues to create added value.
