There are many types of sealants. Silicone sealants are a type of adhesive that is simple to construct. This type of adhesive is mainly used in the field of bonding and fixing, similar to "glue". Usually, as long as the glue is squeezed out, there is no need to make too much preparation and the curing reaction will occur until it is completely cured. Many "accidents" during the curing process will cause the curing speed to slow down.
What are the reasons for the slow curing speed of silicone sealants?
1. Construction temperature. Construction temperature is very important. silicone sealants need to be cured at room temperature. If the curing environment temperature is below zero, the curing speed of the glue will be relatively slow.
2. Ambient humidity. silicone sealants rely on air humidity to undergo vulcanization reaction. The lower the humidity, the slower the curing speed. When the humidity of the curing environment is changed, the curing speed can be effectively controlled.
3. The glue is too wide. silicone sealants can be used for bonding and sealing of electrical housings. When the glue gap is too wide, the glue cannot be exposed to sufficient moisture in time, and the curing speed will be relatively slow.
4. Different ingredients. There are many brands of silicone sealants. The raw material ingredients of each brand are slightly different. The curing speed of different ingredients is different. Some brands have good quality and fast curing speed. Buying such products has better quality assurance. For example, TENSAN focuses on the research of sealants and provides customized sealant application solutions. It has a wide range of uses and can be applied to new energy, military, medical, aviation, shipbuilding, electronics, automobiles, instruments, power supplies, high-speed rail and other industries.
Precautions for the construction of silicone sealants:
When constructing silicone sealants, it is necessary to pay attention to the ventilation and breathability of the construction environment, which is not only conducive to the curing of the glue, but also helps the odor of the glue to volatilize and prevent poisoning of the staff. It is normal for the glue to emit some "pungent" odors during the construction process, mainly because the glue contains ethanol.
The main use area of silicone sealants is the field of process manufacturing. If it is used in the home, it is a bit "overkill". After the glue is cured, it not only has good bonding properties, but also has moisture-proof, waterproof, insulation and shock-proof effects.
