Wetling of PMDI-bulanol grafted beech wood. Beech solid wood was subjected to chemical modification with PMDI and PMDI-butanol monoadduct. Due to the modification hydrophobicity of the material was significantly increased. Reduced water wetting was exhibited by higher contact angles which increased from 50 deg for the controls to 105-110 for the modified material.

Zwilżalność drewna bukowego modyfikowanego adduktem PMDI-butanol. Lite drewno bukowe poddano modyfikacji PMDI oraz adduktem PMDI-butanol. W wyniku modyfikacji zaobserwowano duży wzrost hydrofobowości materiału. Zmniejszenie zwilżalności przejawiała się we wzroście kątów zwilżania z 50 stopni dla materiału niemodyfikowanego do 105-110 stopni dla modyfikowanego.
