Synthetic quartz stone quartz stone is under vacuum conditions quartz crystals (94%), resins (6%) and micro pigments and other materials prepared by heterogeneous polymerization techniques use large-sized sheet of quartz, which up to 94% quartz crystals quartz stone countertops for the main structure, making it harder texture closely synthetic quartz synthetic quartz stone quartz stone is manufactured under vacuum and say what a dense non-porous composite material is well suited to play a role in a complex environment. Its quartz surface pH of the kitchen has an excellent corrosion resistance, daily use of a liquid substance will not penetrate the interior of quartz materials | Quartz | Kai Sa Building Materials provided by Kai Sa Building Materials Co., Ltd., Dongguan City.
