What are the hidden dangers of door and window sealant?

1. Bubbles: bubbles appear in the sealant with naked eyes, which will affect the sealing effect and lead to air leakage and water leakage in doors and windows. 2. Voids: Voids in sealant will also affect the sealing effect, resulting in air leakage and water leakage in doors and windows. 3. Fracture: The naked eye fracture of sealant will lead to the loss of sealing performance of sealant, and also lead to air leakage and water leakage of doors and windows. 4. Notch: Notch on the sealant will also cause the sealant to lose its sealing performance with naked eyes, and it will also lead to air leakage and water leakage in doors and windows. 5. Uneven: Uneven sealant will cause the sealant to lose its sealing performance with naked eyes, and it will also lead to air leakage and water leakage in doors and windows. 6. Pollution: The naked eye pollution of sealant will affect the sealing effect, resulting in air leakage and water leakage of doors and windows.
