Improving the performance of urea-formaldehyde wood adhesive system using dendritic poly(amidoamine)s and their corresponding half generations

Abstract

Full as well as half generations of dendritic poly(amido amine)s (PAMAMs) were introduced onto urea-formaldehyde (UF) wood adhesive system as modifiers to increase its stability and enhance the performance of the bonded wood joints with it. The effect of the modifiers on the physical properties and mechanical performance was discussed on the light of gel times, curing exotherms using differential scanning calorimetry (DSC), infra-red (IR), and shear strength measurements. © 2009 Wiley Periodicals, Inc.
