Chestnut hydrolysable tannins are phenolic materials that have been considered too unreactive to compete in the phenolic resin adhesives market for exterior boards for the building industry. However, an article in 1973 describing 3 years industrial application of chestnut hydrolysable tannins during the first oil crisis indicated that this was not the case. We have extended this old work by using superior phenolic resins formulations and producing phenol–formaldehyde–chestnut tannin adhesives… 

Development and Characterisation of Phenolic Foams with Phenol-Formaldehyde-Chestnut Tannins Resin

With the depletion of fossil resources, tannin extracts can be a natural alternative to some synthetic products. Hydrolysable chestnut tannin extracts have been used to partially replace phenol in PF

Soy-based, tannin-modified plywood adhesives

ABSTRACT In this research, two different types of commercial tannins, namely a hydrolysable tannin (chestnut) and a condensed flavonoid tannin (mimosa), were used to prepare two types of soy-based

Improving soy-based adhesives for wood particleboard by tannins addition

Two different types of commercial tannins, namely chestnut (a hydrolysable tannin) and mimosa (a condensed flavonoid tannin), were used with two different types of hardener, namely hexamine and

Natural Tannins as New Cross-Linking Materials for Soy-Based Adhesives

Based on the results obtained from the thermo-mechanical analysis, the modulus of elasticity (MOE) of soy adhesive is increased by adding tannins to its formulation, and the chemical bond formation was proved by MALDI-ToF-MS.

Reactivity, characterization and mechanical performance of particleboards bonded with tannin resins and bio hardeners from African trees

ABSTRACT Gilbertiodendron dewevrei tannin extract was characterized using MALDI–ToF and CP MAS 13C NMR methods. These two characterization methods have proven that catechin gallate is the dominant

Structural Properties and Copolycondensation Mechanism of Valonea Tannin-Modified Phenol-formaldehyde Resin

In this study, the renewable resource valonea (Quecus acutissima Carr) tannin (VT) was used to partially replace phenol in the production of a phenol-tannin-formaldehyde (PTF) resin by batch

Chemical analysis and thermal stability of African mahogany (Khaya ivorensis A. Chev) condensed tannins

Abstract The forest policies of new Congo basin countries have increased the wood timber industry output since the year 2000. Thus, a high content of underutilized wood waste from sawmill, furniture




Past efforts aimed at replacing the phenolic material in wood adhesives by tannins of various origins have been extensive throughout the world, with research activity normally paralleling the price

The chemistry and development of tannin-based adhesives for exterior plywood

Condensed tannins are phenolic in nature and undergo reaction with formaldehyde to form resins. Tannin/formaldehyde condensates tend to have a low degree of condensation resulting in bonds lacking

Phenolic and tannin‐based adhesive resins by reactions of coordinated metal ligands. I. Phenolic chelates

Bivalent and trivalent metallic ions, respectively, accelerate and inhibit the reaction of phenols with formaldehyde. The catalytic effect of these metallic ions is equivalent, though more marked, to

Polymer structure of commercial hydrolyzable tannins by matrix‐assisted laser desorption/ionization‐time‐of‐flight mass spectrometry

The structures of six commercial hydrolyzable tannins, chestnut, oak, tara, sumach, chinese gall, and turkey gall tannins have been examined by matrix-assisted laser

Particleboard dry and wet I.B. -forecasting by gel time and dry TMA bending in PF wood adhesives

Materials and methods Six phenol-formaldehyde (PF) resins of molar ratios of P:F of respectively 1:1.2, 1:1.4, 1:1.7, 1:2.0, 1:2.5 and 1:2.8 were prepared according to procedures already reported 1.
