UF-pMDI Hybrid Resin for Waterproof Particleboards Manufactured at a Shortened Pressing Time

The aim of the study was to determine properties and potential shortening of pressing time of particleboards resinated with urea-formaldehyde (UF) resin thanks to its modification with pMDI (polymeric 4,4’ - methylene diphenyl isocyanate), introduced to the resin at 2.5 – 10 %. Tests showed that str...
