“…The results show that WG-dispersions are film forming and already in these early developed adhesives fulfil the demands and durability in several niche applications i.e. furnitures for in-door use [19]. However, the wetting and flow of WG needs further investigation.…”

“…Wheat gluten is a by-product from the production of wheat starch and bioethanol, and has been studied as a binder for wood adhesives with promising results [34][35][36][37][38][39][40][41][42][43][44]. Other proteins that have been evaluated are, for example, zein protein [45], pea protein [45], canola protein [46,47], cotton-seed protein [47], triticale protein [48], and lupine protein [49,50].…”

Today's society relies heavily on glued wood products for constructions, furniture, and floorings, for example. Essentially, all adhesives on the market are based on fossil-based resources, and many also contain formaldehyde to yield sufficient reactivity and adhesive performance. Formaldehyde is soon to be banned from consumer goods in Europe, due to its carcinogenic and allergenic features. With the rapidly growing societal environmental awareness, it becomes evident that it is crucial to seek greener, more sustainable alternatives. There is nothing new to this idea; on the contrary, prior to the advent of synthetic polymers, a range of biopolymers such as proteins and starch, were successfully used. However, since adhesives based on synthetic polymers were found to perform better, especially regarding the water resistance, the naturally sourced adhesives have had a subordinate role up until recently. The growing interest for using bio-polymers from renewable resources, such as wood/forest, corn, and cereals have spurred significant R&D developments toward the use of bio-polymers in green wood adhesives. The scope of the present chapter is to summarize, in short, some of the most recent scientific literature regarding the development of green adhesives.

“…A colagem é uma etapa fundamental para o melhor aproveitamento do material madeira, tanto no setor moveleiro quanto na construção civil (FRIHART, 2011;LIMA et al, 2008;DEL MENEZZI, 2010). No entanto, os trabalhos existentes na literatura tratam da avaliação da interação entre madeira e adesivo para compensados pela variação da gramatura (ALBINO et al, 2011;ALMEIDA et al, 2004), sendo que há uma escassez de estudos dessa natureza para painéis particulados (KHOSRAVI et al, 2011).…”

Objetivou-se, neste trabalho, avaliar a qualidade do encolamento de partículas "strand" e a influência desse processo na qualidade final da colagem em painéis OSB. Realizou-se a mensuração das dimensões e determinação da massa de 658 partículas antes e após o processo de encolamento. As variáveis gramatura (g.m-2) e a quantidade efetiva de adesivo aplicado (%) foram avaliadas. Aplicaram-se os teores de 6, 9 e 12 % de adesivo fenol-formaldeído em partículas de Pinus oocarpa e Eucalyptus grandis. Foi realizado o teste de tração perpendicular nos painéis produzidos. O processo de encolamento de partículas "strand" em laboratório é heterogêneo, o que dificultou analisar a influência das variáveis de processamento sobre a quantidade efetiva de adesivo aplicado e gramatura. Foi verificado que painéis OSB produzidos com a espécie Pinus oocarpa apresentaram menor gramatura de partículas em relação aos painéis de Eucalyptus grandis. Esse resultado foi atribuído a menor densidade básica da madeira de Pinus oocarpa. Observou-se que maiores gramaturas na partícula estão, positivamente, relacionadas com a resistência à tração perpendicular.
