The health index of silicone sealant is one of the important evaluation criteria for its performance.

Among them, acid sealant due to its large pungent smell, although it will not cause harm to the human body, but affect the comfort of construction, and the applicable substrate is limited, and gradually phased out; At present, the common decoration on the market mainly uses single-component neutral silicone sealant; The neutral glue will release small organic molecules such as alcohols during the curing process, and in the standard curing environment, it usually takes 3-5 days to completely cure, and the released small molecules will not have any odor after completely volatilizing.
