What is weather sealant

Weather sealant has excellent weather resistance such as ozone resistance and ultraviolet resistance, giving it a long service life.

The main function of weathering glue is to seal the indirect seams of the plates. As the plates are often affected by temperature changes and deformation of the main structure, they will be displaced, resulting in changes in the width of the joints. This requires the weather resistant adhesive to have a good ability to withstand the displacement of the joint, and it will not crack when the joint width changes for a long time. This performance is called the displacement capacity of the weather resistant adhesive, and the "displacement bearing capacity" of the structural adhesive. different

Among the main technical indicators of silicone weathering sealant, the construction performance is characterized by sag, extrudability, and surface drying time, and the performance of the cured weathering sealant is mainly displacement ability and mass loss rate. The quality loss rate of weathering adhesive is equivalent to the thermal weight loss of structural adhesives. It mainly investigates the performance changes of weathering adhesive after long-term use. The higher the quality loss rate, the more serious the performance degradation after long-term use.

1. Suitable for weather-resistant sealing of various curtain walls, especially recommended for weather-resistant sealing of glass curtain walls, aluminum-plastic panel curtain walls, and stone dry hanging;
2. Sealing the joints between metal, glass, aluminum, ceramic tiles, plexiglass, and coated glass;
3. Seam sealing on the surface of concrete, cement, masonry, rock, marble, steel, wood, anodized aluminum and painted aluminum.
