Optimization and characterization of melamine urea formaldehyde (MUF) based adhesive using natural fillers for plywood

In this research, Palm Kernel Meal (PKM) and Palm Shell (PS) were studied as a filler for wood adhesive formulation and compared with present industrial filler (IF), wheat flour.Melamine Urea Formaldehyde (MUF) resin was selected as the resin for formulating the wood adhesive. The e...
