Abstract

Microscopic studies on non-pressed chips glued with polymeric diphenylmethane diisocyanate (MDI) and on some particleboard cross-sections showed that due to its good wetting properties this glue effects a good thin-layer spread on the surface of the wooden chips. Due to capillar action MDI completely penetrates cracks in the chips. Moreover, there was evidence that MDI is capable of penetrating the cell walls. Particleoboard cross-sections showed that most of the earlywood portion in chip mixes was evidently completely saturated with MDI.
