-Two types of thermosetting resins MUF and UF have been used as glues for birch wood veneer. As resins modifiers polyvinylacetate emulsion (PVA), polyvinylbutiral (PVB) (powder and solution), rubber latex, adipic (Ad) and sebacic (Seb) acids have been utilized. For glued system shear strength and deformation, bending properties and impact strength have been tested. The best properties: adhesive activity and elasticity have been shown by resins modified with PVB powder, rubber latex, adipic and sebacic acids.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
