What is silicone sealant? In the process of use, adhesive foaming, delamination, cracking and other problems continue to appear, the adhesion becomes worse, what is this situation? Here, the building sealant sales manufacturers to share a few content, we take a look!

Silicone sealant is a kind of daily adhesive, strong adhesion, not easy to scratch, can maintain adhesive performance for a long time.

1, the quality of sealant itself

The crosslinking content is small, not enough to form the crosslinking network structure, the sealant reaction is perfect. There are structural defects, easy to cause colloidal cracks. The sealant is not used in the effective period, and the displacement capacity, coefficient and scalability after curing do not meet the requirements of use.

2. Construction reasons

The surface of the device is clean and cannot meet the requirements of sealant. When applying sealant, the surface of the equipment will not volatilize and dry. The sealant did not sufficiently compress the sealant at the interface during the test run. The contact area between the sealant and the device is too small to ensure the adhesion between the sealant and the device. If the sizing is thick and uneven, the colloid will crack easily in thin places.

3. Construction environmental factors

When the surface temperature of sealant is too high or too low, the colloid is easy to crack after hardening. During construction, when the ambient temperature is lower than 5 ° C, condensation and hidden channels will appear on the surface of the equipment.

4. External force factor

Silicone sealant in the curing process, will be subjected to large external force or equipment deformation (such as earthquake, typhoon, etc.), the colloid may crack.
