Lignin residues from biorefineries consist of a growing raw material source but lack reactivity. Two crosslinkers were tested for ammonium lignosulfonate (ALS)\u2014bio-based furfuryl alcohol (FOH) and synthetic polymeric 4,4\u2032-diphenylmethane diisocyanate (pMDI). The addition of mimosa tannin to ALS before crosslinking was also evaluated. The derived ALS adhesives were used for gluing 2-layered veneer samples and particleboards. Differential Scanning Calorimetry showed a reduction of curing temperature and heat for the samples with crosslinkers. Light microscopy showed that the FOH crosslinked samples had thicker bondlines and higher penetration, which occurred mainly through vessels. Tensile shear strength values of 2-layered veneer samples glued with crosslinked ALS adhesives were at the same level as the melamine reinforced urea-formaldehyde (UmF) reference. For particleboards, the FOH crosslinked samples showed a significant decrease in mechanical properties (internal bond (IB), modulus of elasticity (MOE), modulus of rupture (MOR)) and thickness swelling. For pMDI crosslinked samples, these properties increased compared to the UmF. Although the FOH crosslinked ALS samples can be classified as non-added-formaldehyde adhesives, their emissions were higher than what can be expected to be sourced from the particles.<\/jats:p>","DOI":"10.3390\/polym11101633","type":"journal-article","created":{"date-parts":[[2019,10,11]],"date-time":"2019-10-11T03:07:11Z","timestamp":1570763231000},"page":"1633","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":58,"title":["Ammonium Lignosulfonate Adhesives for Particleboards with pMDI and Furfuryl Alcohol as Crosslinkers"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5188-4817","authenticated-orcid":false,"given":"Venla","family":"Hemmil\u00e4","sequence":"first","affiliation":[{"name":"Department of Forestry and Wood Technology, Linnaeus University, L\u00fcckligs plats 1, 351 95 V\u00e4xj\u00f6, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6909-2025","authenticated-orcid":false,"given":"Stergios","family":"Adamopoulos","sequence":"additional","affiliation":[{"name":"Department of Forestry and Wood Technology, Linnaeus University, L\u00fcckligs plats 1, 351 95 V\u00e4xj\u00f6, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0883-2306","authenticated-orcid":false,"given":"Reza","family":"Hosseinpourpia","sequence":"additional","affiliation":[{"name":"Department of Forestry and Wood Technology, Linnaeus University, L\u00fcckligs plats 1, 351 95 V\u00e4xj\u00f6, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6390-7377","authenticated-orcid":false,"given":"Sheikh Ali","family":"Ahmed","sequence":"additional","affiliation":[{"name":"Department of Forestry and Wood Technology, Linnaeus University, L\u00fcckligs plats 1, 351 95 V\u00e4xj\u00f6, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,10,10]]},"reference":[{"key":"ref_1","unstructured":"International Agency for Research on Cancer (IARC) (2004).
