How can silicone sealants change the slow curing properties of thick layers of adhesive? Is it safe to use?

Silicone sealant is simple to operate, no two-component sealant cumbersome, as long as the squeeze out the glue can be directly constructed, because of the product characteristics, mainly used in bonding fixed parts, many electrical appliances shell also use silicone sealant glue gluing, the use of many years did not occur yellowing phenomenon.

Silicone sealant curing characteristics:

The higher the humidity of the air, the higher the temperature of the curing environment, the faster the curing speed. In the curing process, the surface drying time is only about 3 to 15 minutes, the overall curing time depends on the construction of the rubber layer, the rubber layer after the curing slower.

How to change the characteristics of the thick layer of rubber curing slow?

1Change the humidity of the curing environment, the construction of a thick layer of rubber, the deep layer of rubber can not be in contact with moisture in time, can not quickly occur in the vulcanization phenomenon. Changing the humidity of the air can accelerate the curing speed.

2, layered injection, because the deep layer of glue can not be timely access to moisture in the air, can be a layered injection, to effectively solve the characteristics of the thick layer of glue curing slow.

Is it safe to use silicone sealant?

When working with silicone sealants, a small amount of alcohol is contained in the glue and some alcoholic odors are released during the process, which is not affected by wearing a mask or other protective measures. The alcohol in the adhesive will disappear slowly as it cures and will disappear completely when it is completely cured.

One-component sealant and two-component sealant raw materials, performance, use methods are different, there are major differences in the field of use, the user must be distinguished when buying, do not get it wrong.
