For many non-professionals, sealants may still be heard a little bit, and they can also have a general understanding of the performance and use of sealants as the name implies. But if the question is: "What is a silicone sealant", then few people may know it. So, what is a silicone sealant? What performance and features does it have?
What is silicone sealant
From the point of view of use, we can define silicone sealant in this way: Silicone sealant is often used to fill the gap between structures, play the role of bonding and sealing, and they also have anti-leakage, waterproof, vibration-proof, sound insulation Excellent heat insulation effect.
From the material point of view, we can look at the silicone sealant in this way: use polydimethylsiloxane as the main raw material, add some auxiliary materials such as crosslinking agent, filler, plasticizer, coupling agent, catalyst, etc. In the state, it is mixed according to a certain ratio, and finally forms a paste.
In principle, silicone sealant reacts with water in the air at room temperature to form elastic silicone rubber, so as to achieve the effect of bonding and fixing.
How does silicone sealant perform?
The appearance of silicone sealant can be divided into transparent, white and black, and there are two states of paste and semi-paste. It smells like mellow. TENSAN silicone sealant has three specifications: 100ml, 300ml and 2600ml. It forms a sealant through humid air vulcanization, its surface dry time is about 3 to 15 minutes, and its curing time is about 24 hours. Silicone sealants are resistant to high and low temperatures, and can be used in a wide range of temperatures, from -50°C to 200°C. At room temperature, the silicone sealant cures from the surface to the inside, so there is no need to worry about sticking hands and other problems, and the operation is very convenient. The material fully complies with ROHS, REACH and other environmental protection requirements, so you can use it with confidence.
To sum up, the performance of silicone sealants is very good. In terms of selection, we can choose according to our actual situation. It is recommended to choose the ones with guaranteed quality and use them with more confidence.
