In this study, effects of urea formaldehyde-melamine formaldehyde resins pick-up percentages, raw paper weight, impregnation/coating process and total resin pick-up (TRPU) percentage on the resistances to the scratch (SR), abrasion (AR) cigarette bums and staining of melamine-impregnated papers (melamine coaters) were investigated. As the urea formaldehyde resin pick-up in the impregnation was increased, the scratch and abrasion properties significantly decreased. Raw paperweight did not affect these properties, statistically. Increasing the TRPU improved the SR and AR. One-step process had higher SR and AR values than those of two-step process. Impregnation process caused important changes in the resistances to the staining and cigarette bums. (C) 2004 Elsevier Ltd. All rights reserved.
