Silicone sealant is a kind of sealant. This sealant will undergo a curing reaction as long as it comes into contact with water vapor in the air at room temperature. Once cured, it will form an elastic colloid that does not corrode metals. Safety, as long as it reaches the environmental protection level, it will not affect human health.
How waterproof is silicone sealant?
1. Silicone sealant has very good waterproof performance. Once the glue solidifies, it will show good bonding and sealing effects, and can prevent the intrusion of water and moisture. Good-quality products have unchanged performance after many years of use, such as TENSAN, which specializes in sealants. Research and provide customized sealant application solutions. Common areas of use are: household appliance shell bonding, LED lights, car lights, power switches, etc.
2. Although silicone sealant has good waterproof performance, it can only be used as daily waterproofing and cannot be used as a waterproof material for bonding underwater electrical appliance shells. If it is soaked in water for a long time, the viscosity of the glue will be affected and it cannot be used. Use it in a humid environment for a long time to avoid damage to the performance of the glue.
Does silicone sealant have strict requirements on the construction environment?
1. When silicone sealant is being constructed, the construction site must have air circulation to facilitate ventilation. Because the glue contains ethanol, it will release an alcoholic smell during the construction process. If these smells cannot be dissipated or evaporated in time, it will be harmful to human health if inhaled in large amounts.
2. It is more conducive to construction to keep the construction environment at room temperature as much as possible. The lower temperature of the construction environment affects the overall curing speed. If the curing time is too long, the overall performance of the glue will also be affected.
Silicone sealant not only has strict requirements for the construction environment, but also has strict requirements for the construction base material. The surface of the construction base material must be clean and tidy without any impurities, otherwise it will affect the bonding strength and be easy to deglue after curing.
Silicone sealant is a common adhesive. It is normal for this adhesive to release some alcoholic odor during the construction process. As long as the operator takes relevant protective measures and ensures ventilation in the construction environment, there will be no impact.
