Recently, Elkem Silicones’ STARSIL™ XH-9201 two-component silicone structural sealant has been awarded the prestigious 25-year “Engineering Material Aging Resistance Certificate,” the highest honor in China, owing to its exceptional performance.
STARSIL™ XH-9201, a two-component silicone structural sealant independently developed by Elkem Xinghuo Silicones, meets China’s strictest standards for silicone structural sealants in building curtain walls, JG/T475-2015.
Following its successful application in the Sinochem Holdings buildings project in Xiong’an New Area, it garnered widespread acclaim from industry experts. The China National Building Waterproof Association’s award of the top-tier 25-year “Engineering Material Aging Resistance Certificate” to XH-9201 aims to promote quality upgrades in domestic sealants and drive the high-quality development of the building sealant industry through authoritative endorsement.
The aging resistance test for engineering materials is extremely rigorous, demanding that the product endure a water-UV light aging test lasting up to 1,008 hours. During this period, the sealant must withstand cumulative radiation exposure within the wavelength range of 300nm-400nm, totaling up to 217,728 kJ/m² of radiation. Authoritative testing has fully demonstrated that STARSIL™ XH-9201 Structural Sealant is capable of providing over 25 years of safety assurance for building structures.
This top-tier certification for aging resistance is another testament to Elkem Silicones’ commitment to specialization in the building sector. It will significantly bolster Elkem Xinghuo Silicones’ prominence in China’s building sealant industry and further propel the company’s high-quality development.
