For many nonprofessionals, they may have heard of the sealant and have a general understanding of the performance and use of the sealant. But if the question is "what is silicone sealant", few people may know it. So, what is silicone sealant? What are its performance and characteristics?
(1) From the perspective of application, we can define silicone sealant as follows: silicone sealant is often used to fill the gap between structures and play the role of bonding and sealing. At the same time, they also have excellent effects such as leakproof, waterproof, shockproof, sound insulation and heat insulation.
(2) From the material point, we can look at silicone sealant as follows: Polydimethylsiloxane is used as the main raw material, by adding some auxiliary materials such as crosslinking agent, filler, plasticizer, coupling agent and catalyst, in the vacuum state, it is mixed according to a certain proportion and finally forms a paste.
(3) In principle, antibacterial silicone sealant is cured to form elastic silicone rubber by reacting with water in the air at room temperature, so as to achieve the effect of bonding and fixation.
The appearance of silicone sealant can be divided into white and black, including paste and semi paste. It smells like alcohol. There are three specifications of silicone sealant commonly used: 100ml, 300ml and 2600ml. It forms sealant by wet air vulcanization. Its surface drying time is about 3 ~ 15 minutes and curing time is about 24 hours.
Antibacterial silicone sealant can withstand high and low temperatures, and has a wide range of temperature applications, ranging from -50℃~200℃. At normal temperature, the antibacterial silicone sealant solidifies from the surface to the inside. There is no need to worry about sticking hands and other problems. The operation is very convenient. The material fully complies with ROHS, REACH and other environmental protection requirements, and you can rest assured to use and buy silicone sealant.
In conclusion, the performance of silicone sealant is very good. We can choose it according to our actual situation. It is recommended to choose one with guaranteed quality and use it more safely. If you want to purchase silicone sealant, please considering ZHONGTIAN EAST first!
