Curing and Adhesive Bond Strength Development in Naturally‐Based Adhesives

Binderless particleboards obtained 100% from winery by-products for the packaging industry

“…As it was previously discussed, hot water extraction has low efficiency to recover phenolics and flavonoids from grape stalks when compared to alkaline extraction agents (Table 2). In the literature, it is referred that the liquid extraction of lignocellulosic biomass, as grape stalk, generates a mixture of long-and short-chain polymers that can be successfully used as bioadhesives in several industries (Muranaka et al, 2017;Ferreira-Santos et al, 2020;Sun et al, 2022;Zhang et al, 2022;Li et al, 2023;Šernek and Žigon, 2023). The bonding potential is commonly associated with the presence of phenolic compounds, and a high amount of polyphenols usually results in an enhanced bonding capacity of the extracts (Friedman and Jürgens, 2000;Benito-González et al, 2020;Oriez et al, 2020;Troilo et al, 2021;Rodrigues et al, 2023).…”
