Paper impregnated and coated with thermosetting resins is usually used as a decorative andprotective laminate for wood panel [1]. In the present study, Melamine Formaldehyde (MF)and Urea Formaldehyde (UF) and three raw papers from different suppliers (Wenge, Oliveash& Gruen) were used for impregnation process in lab scale to see the influence of some importantmanufacturing variables on the products quality. The resin picks up, weight of rawpaper, percentage of UF and MF blending were investigated by some quality tests such asscratch resistance (SR), abrasion resistance (AR) and resistance to steam according to EuropeEN438-2 standard test method [2]. As the UF resin pick up in impregnation process was increased,the scratch and abrasion properties decreased. The raw paper weight (RPW) didn’taffect the properties of the panel same as SR and AR, but these parameters were significantlyimproved by increasing the MF resin pick-up (Table. 1) and is showed that MF resin is moreresistance to mentioned tests than UF resin
