Why does silicone sealant wrinkle after curing? What are the common reasons?

Silicone sealant is a single-component glue liquid. This glue liquid is easy to construct. The seemingly simple construction method hides many mysteries. If you are not careful, various problems will occur, causing the colloid to reduce its use value or lose its use value. Reasonable and standardized use is very important, and it is necessary to hire professionals for construction.

Why does silicone sealant wrinkle after curing?

1. The construction environment temperature varies greatly between day and night. After the silicone sealant is constructed, it is best to cure it in a room temperature environment. In an environment with a large temperature difference, the adhesive material and the glue will expand and contract after heat expansion and cold contraction, which will cause the surface of the colloid to wrinkle and there will be no shiny film.

2. The construction environment of silicone sealant needs ventilation, which is conducive to the curing of the glue liquid and the dissipation of odor. After construction, if the bonding surface is vibrated or swung by the wind, the surface of the colloid will wrinkle after curing.

3. In order to reduce costs during the construction stage, the thickness of the construction glue layer is changed. When the glue layer is cured in a relatively thin condition, it is easy to wrinkle. This situation can be effectively avoided. Standardize the construction during the construction stage and do not cut corners.

Does silicone sealant wrinkle after curing?

After curing, the surface of silicone sealant wrinkles, and its waterproof and moisture-proof properties are reduced. Its corrosion resistance and hydrochloric acid resistance will also be reduced, which will reduce its use value. Try to avoid this situation during construction. In addition, the quality of branded products is more guaranteed, which can reduce many accidents. 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.

Silicone sealant is elastic after curing and is not easy to crack after vibration. It can be used in electrical components to increase the service life and use value of electrical appliances. It is very important to buy good quality ones. It will not crack, will not crack, and will not seep water after many years of use, but it cannot be soaked in water. Over time, the colloid will be soaked and lose its use value.
