7 Professional Prodution Process And Strict Quality Control
Safety:
It has no toxicity after entirely cured. Avoid eye contact it when operating. If happened, rinse opened eye under running water for several minutes. During the curing process, sealant will release a small amount of organic molecules. Construction should ensure good ventilation. If necessary, take protective measures. Please keep out of reach of children.
