Silicone sealant is a type 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. This colloid is not corrosive to metals and will not affect human health as long as it reaches the environmental protection level.
How is the waterproof performance of silicone sealant?
1. Silicone sealant has good waterproof performance. Once the glue is cured, it will show good bonding and sealing effects, which can prevent water and moisture from invading. Good quality products will remain unchanged for many years. For example, TENSAN focuses on the research of sealants and provides customized sealant application solutions. Common use areas are: household appliance housing bonding, LED lights, car lights, power switches, etc.
2. Although silicone sealant has good waterproof performance, it can only be used as daily waterproofing, not as a waterproof material for underwater electrical housing bonding. If it is soaked in water for a long time, the viscosity of the glue will be affected. It cannot be used 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 alcohol smell during the construction process. If these smells cannot be dispersed or volatilized in time, they will be harmful to health if inhaled by the human body in large quantities.
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 extended too much, the overall performance of the glue will also be affected.
Silicone sealant not only has strict requirements on the construction environment, but also on the construction substrate. The surface of the construction substrate must be kept clean and tidy, without any impurities, otherwise it will affect the bonding strength and it is easy to debond after curing.
Silicone sealant is a common adhesive. It is normal for this adhesive to release some alcohol smell during the construction process. As long as the operator takes relevant protective measures and ensures the ventilation of the construction environment, there will be no impact.
