Beschreibung
Zusammenfassung:	The present invention relates to a PVC / CPVC solvent cement formulations using less toxic ketonic solvent mixtures comprising of first three members in homologous series of ketones having one low boiling ketone with boiling point less than 70°C and solvent mixture having two medium boiling ketones with boiling point around 100°C. The solvent cement formulation disclosed in the present invention is less toxic, low VOC and fast curing method of preparing said composition comprising PVC/CPVC solvent cement, which is less toxic, low VOC, fast curing and cost effective. La présente invention concerne des formulations de ciment à solvant PVC/CPVC utilisant moins de mélanges de solvants cétoniques toxiques comprenant trois premiers éléments dans une série homologue de cétones ayant une cétone à bas point d'ébullition avec un point d'ébullition inférieur à 70 °C et un mélange de solvants ayant deux cétones à point d'ébullition moyen autour de 100 °C. La formulation de ciment à base de solvant divulguée dans la présente invention est moins toxique, à faible teneur en COV et à prise rapide de préparation de ladite composition comprenant du ciment à solvant PVC/CPVC, qui est moins toxique, à faible teneur en COV, à prise rapide et rentable.
