Quebracho tannin - hyperbranched polyglycerol blends as adhesives for wood bonding. Applicability of tannin-hyperbranched polyglycerol blends cured with hexamine in wood bonding was investigated. Adhesive performance of the systems was examined. It was shown that strengths of adhesive joints exceeded that of the substrate, therefore it was concluded that hyperbranched polyglycerols might be effective components of tannic adhesives.
