The invention relates to a formulation comprising: - a first component which is formed from at least one isocyanate and at least one polyether, wherein said polyether comprises at least one ethylene oxide moiety and at least one isocyanate reactive group selected from the group comprising hydroxyl...
Numerous studies on wood adhesive development utilize natural phenolic compounds, tannins, technical lignin, cellulose, plant-derived starch, and other renewable resources, often derived from bio sources. These are employed either in the formulation of formaldehyde containing adhesives used in wood board ...

The wood adhesive was prepared by blended protein with soluble starch solution and ortho- phosphoric acid and the prepared adhesive formulation was applied in wood samples (Ply wood, Formica, Chip board) in different sizes. The effect of steam from boiling water on joined various wood samples ...
The non-woven mat is a tightly entangled web of fibres that lacks strength unless its integrity is increased with an adhesive. Entangled combinations of fibres can be formed by weaving or felting where one of the fibre types can melt to form the matrix while the other fibre remains as the ...
In this review, what will be dealt with will be (1) the elimination of toxic aldehydes from the most common wood panel adhesive, the one based on urea, itself a natural product, (2) biosourced adhesives derived from wood or other vegetable matter and used for wood products, and (3) ...
Pine tannin-based adhesive formulations suitable for the industrial manufacture of exterior grade particleboard are discussed. The formulations described are a combination of substantial amounts of pine tannin extract with melamine-formaldehyde, phenolformaldehyde and diisocyanate wood adhesives. The pine tann...
*gram weight foliage addition to the adhesive standard formulation: psi = shear strength; WF(%) = percent wood failure. The 1.5 and 5.5 gram weight additions are equivalent to the 2.2 and 8.1% glue weight respectively. From Table 5, the use of foliage in the adhesive formulation gave practi...
