How does silicone sealant change the slow curing characteristics of a thick adhesive layer? Is it safe to use?


Silicone sealant is easy to operate and is not as cumbersome as two-component sealant. Just squeeze out the glue and it can be applied directly. Because of its product characteristics, it is mainly used for bonding and fixing parts. Silicone sealant is also used on many electrical appliance casings. It is bonded and has not turned yellow after many years of use.

Silicone sealant curing characteristics:

Silicone sealants rely on air humidity for vulcanization. The higher the air humidity, the higher the curing environment temperature and the faster the curing speed. During the curing process, the surface drying time only takes about 3 to 15 minutes. The overall curing time depends on the construction adhesive layer. The later the adhesive layer is, the slower it will cure.

How to change the slow curing characteristics of the adhesive layer that is too thick?

1. Change the humidity of the curing environment, the construction glue layer is thicker, and the deep glue liquid cannot contact the moisture in time, and the vulcanization phenomenon cannot occur quickly. Changing the air humidity can speed up curing.

2. Glue injection in layers, because the deep glue liquid cannot contact the moisture in the air in time, glue can be injected in layers, which effectively solves the problem of slow curing of the glue layer that is too thick.

Is silicone sealant safe to use?

During construction, because the glue contains a small amount of alcohol, some alcohol smell will be released during the construction process. As long as you wear a mask or other protective measures, it will not have an impact. The alcohol in the glue will slowly disappear as it solidifies, and will disappear completely after complete solidification. It does not contain any alcohol after solidification, has no corrosion to metal, and has no impact on the human body.

When purchasing silicone sealant, it is more secure to look for products from big brands, such as TENSAN, which focuses on the research of sealants and provides customized sealant application solutions. It has a wide range of uses and can be used in new energy, military industry, medical, etc. Aviation, shipbuilding, electronics, automobiles, instruments, power supplies, high-speed rail and other industries.

One-component sealant and two-component sealant have different raw materials, properties, and usage methods, and their fields of use are quite different. Users must distinguish them when purchasing to avoid making a mistake.
