In building construction, sealant products are generally used, although the use effect is good, but there will inevitably be some problems. Below, building sealant manufacturers and share some common problems and solutions, take a look together!

    1. It is not bonded to the substrate

    The main reason is that no bonding test is carried out before construction, the curing temperature is too low, and the relative humidity is too high. During construction, the curing temperature should be increased, the curing time should be extended, the surface treatment of the substrate or the sealant should be replaced.

    2. Slow curing speed

    The main reasons are low ambient temperature, low humidity, glue seam is too narrow, too deep, sealant expired, etc. During construction, the curing temperature and humidity should be increased, two times of gluing or double-sided gluing, and the sealant should be replaced.

    3. Create bubbles

    The main reason is that when the glue is wrapped in air, moisture intrusion into the glue seam, substrate and some sealant reaction. During construction, glue should be injected uniformly, continuously and fully into the interface, and the interface and accessory materials should be dry.

    4. Play the drum

    The main reasons are large plate size, large expansion coefficient leading to joint deformation, plate day and night temperature difference, low humidity and so on. During construction, sealant with relatively fast curing speed should be selected, and appropriate shading measures should be adopted to reduce panel temperature.

    5. Cracking and leaking

    The main reason is that the joint is too narrow, the seal is not in place, the sealant displacement capacity is insufficient, the sizing thickness is too thin. During construction, joints should be designed according to the specification requirements, sealant with good displacement capacity should be selected, construction should be carried out according to the operation specifications, and the thickness of sealant should be optimized to avoid three-side bonding.

    Specific problems are analyzed and solved according to the actual situation. Friends who want to purchase products can contact Xiangyang Auman Environmental protection Materials Co., LTD., a professional manufacturer. Welcome to inquire!
