Lignin Modification to Produce Sustainable Polyurethane Resin for Wood Coatings
2014 - IRG/WP 14-40682
The use of lignin as the most abundant aromatic natural polymer has been evaluated for use in the production of lignin-based polyurethane resin for coating applications. Coatings are made of resins (ca. 50%), which today are mainly derived from petroleum-based polymers. This study is focused on the development of an environmentally friendly method of modifying lignin to be used as source of natura...

Lignin-Based Adhesive for Engineered Wood Products
2016 - IRG/WP 16-50319
Lignin as a naturally occurring polyphenolic compound has an excellent potential to replace petroleum-based phenol in formulation of phenol-formaldehyde adhesive that are used in manufacturing of engineered wood products. However, there are three major obstacles in application of polymeric lignin as phenol replacement: 1) low reactivity toward phenol, 2) high molecular weight, and 3) high polydisp...
