Baiyun Chemical did 50-Year Limit Test for Glass Sealant

Silicone sealant resistance to weathering and aging has attracted much attention

Building curtain wall is the product of the development of modern science and technology, which is a significant feature of the high-rise buildings in modern era. All kinds of curtain walls can make the appearance of the building to produce extensive changes and realize strange building effects, so they are loved by the building designers. As the most important bond carrier in the curtain wall structure, the resistance to weathering and aging of silicon sealant in the process has attracted much attention in the industry.

Baiyun Chemical is carrying out up to 50 years of atmospheric environment natural aging test for structural sealant

Baiyun Chemical as modern enterprise in domestic sealant industry has a history of nearly three decades, which has paid attention to the safety of the structure sealant application problems at the height of the industry and a strong sense of responsibility. In 1997, Baiyun Chemical self-built a 50-year exposure glass curtain wall in the company square, which regularly derives aging resistance data of structural glass sealant. In order to make the anti-aging experiment more scientific and impartiality, the company signed a 50-year period detection protocol with Guangzhou Chemical Industry Synthetic Materials Aging Quality Supervision and Inspection Center, carrying out up to 50 years of atmospheric environment natural aging test for structural sealant in the natural exposure test site in Guangzhou and Xinjiang region.

Significance of Baiyun Chemical 50-year limit test

The silicone sealant on the market generally provide not more than 25 years of quality assurance. Baiyun Chemical carries out the 50-year limit test in dry, hot and humid environment natural exposure test in Guangzhou and Xinjiang. The atmospheric environment natural aging test data will continue to provide strong data support the research and development of innovative and guidance products under different climatic and environmental conditions, allowing Baiyun Chemical to provide customers with safer and more permanent high-quality silicone sealant, which provides more reliable, scientific and credible standards for the development of industry standards, national and international standards.

The 50-year limit test provide more reliable basis for the design life of the structural silicone rubber in a variety of areas

It is reported that the world's developed countries have established natural exposure test site in the place where there is the typical climate environment. This time Baiyun Chemical selected natural exposure testing ground in Guangzhou and Xinjiang for the 50-year limit test, respectively, they have a typical subtropical hot and humid climate characteristics and northern desertdry hot cold climate characteric. The two have a great contrast, which the climate zone with extreme characteristics. Using natural climate characteristics for structural silicone rubber aging study, investigating the aging resistance of structural silicone gel in cold, hot and humid and other extreme weather conditions can provide more reliable basis for the design life of the structural silicone rubber in a variety of areas.
