Will a D4 PVA adhesive discolour?
D4 PVA adhesives are white, transparent after drying and offer product stability, improved adhesion on difficult wood species (oak and larch) and no discolouration of the glue line when pressing with heat. Good quality D4 PVA adhesives are neutral pH value and thus a much lower probability of discolouration.
