The compatibility test and performance test of silicone structural adhesives with contact materials must be carefully carried out before they are put into stock. In the absence of such a report, the Contractor shall be urged to immediately entrust a testing institution with such qualification to carry out special tests for use only after it is qualified.

Light, colorful and transparent sealants have poor ultraviolet resistance and are only suitable for indoor engineering. Black sealants should be generally used outdoors. The environment for storing glue should meet the requirements of temperature and humidity to ensure a longer service life of the seal.

Building sealing function is to ensure the quality of the building. Different sealing products are selected for different components. The quality assurance of sealing products is to ensure the sealing effect of the building. Here's how to distinguish the quality of sealing resin used in building.

The quality of sealant is distinguished by first observing the appearance, and then using a rubber gun to hit out the colloid, we can see the uniformity of the glue, the higher the better. Glue out, see the gloss of glue, good is crystal luster, good glue is no impurities and bubbles. Use hand dip glue, slowly pull out, the longer the pull, the better, the general good glue are more than 50 centimeters, so you can judge the quality of sealant, the method is simple, easy to operate, easy to master.

Sealants play a basic role in any industry, and so do building sealants. In addition, sealants can also receive sunlight, radiation aging in sunlight, oxidation of oxygen and ozone, erosion of water and steam, influence of environmental temperature changes, wind load and shear force. The effect of cycling machinery (compression/tension) load, aggressive atmospheric pollution and other factors are all beyond words, which is also the specific function he can achieve.

Building sealant has the function of waterproofing and sound insulation. Waterproofing is more important. It often receives the erosion of rainwater. Sound insulation materials are basically chosen. In this respect, the requirements are not very strict. The function of building sealant is enormous, which provides favorable foundation support for building.
