| Abstract | ||
| A study was made on preparation of urea – melamine – formaldehyde (UMF) resin by condensation polymerization technique to produce polymeric adhesive for wood –wood surface. Different weight of urea are used in formulation of resin to achieve the best balance between cost and performance of melamine adhesive which have excellent water resistance, and all prepared samples exhibited high resistance to water. The best results were obtained from the sample (UMF) in using urea (4.8) gm. For this sample different weight of resorcinol are used as reinforcement to prepare tricomponent bonding system (resorcinol, hexamethylenetetramine, and silica) as curing system of adhesive for wood – wood surfaces. Mechanical properties test such as (Impact test, Compression test, and Bending test) was carried on. All results were discussed. | ||
