Sealant is one of the commonly used materials in buildings, which can be used for sealing and bonding various joints or holes in building parts such as building exterior enclosure, interior decoration and window structure. Different building joints have different requirements for the performance of sealant. The sealant used in exterior wall, bathroom, toilet, kitchen, balcony, floor heating system floor, insulating glass and other building parts should have high waterproof and moisture resistance. The water vapor barrier performance is one of the key factors to determine its waterproof and moisture-proof performance, such as the density of sealing insulating glass The water vapor transmission rate of the sealant is high, and the water vapor in the environment will slowly penetrate into the glass through the sealant, resulting in condensation or frosting inside the insulating glass, affecting its service life.

Sealing is an important part of packaging. The quality of sealing directly affects the packaging effect, the storage and service life of packaging materials, and even affects the reputation of packaging materials. According to the form and usage of sealing materials, they can be divided into three types: gasket seal, tape seal and colloidal seal. They can achieve the purpose of preventing liquid leakage, blocking the entry of oxygen, moisture and odor, and preventing fake and inferior products. In particular, anti-counterfeiting sealing is a booming packaging sealing technology in recent years. It is usually sealed with hot melt adhesive or pressure-sensitive adhesive tape. Once the package is folded, it can not be restored to its original state, thus preventing the appearance of fake and inferior products and protecting the interests of consumers.

The sealing performance of sealant is generally good, pay attention to the correct use, the correct method can improve the sealing performance of sealant.

In home decoration, the commonly used sealant is divided into two types: neutral sealant and acid sealant. The general use of sealant in home decoration is: the dumb mouth on the back of wood thread, sanitary ware, toilet, toilet, toilet mirror in the toilet, the gap between the sink and the wall, and so on. These places should use different performance sealant. Neutral sealing adhesive force is relatively weak, generally used in the toilet mirror back, these do not need a strong adhesion force. Neutral sealant used in home decoration is more, mainly because it will not corrode objects, and acid sealant is generally used in the dumb mouth on the back of wood thread, with strong adhesion.
