Choosing the Right Yellow-Resistant Sealant for Your Home
In the past, when choosing sealants for home installation, the most frequently asked question was about mold resistance. Now, the question is quite different. Many homeowners ask right away, "Is it resistant to yellowing?"
This is because many people have encountered a similar situation: when choosing sealants, they didn't pay attention to the yellow resistance, and as a result, the sealant on the balcony and bay windows turned yellow very明显 after a period of sun exposure, which looked quite unpleasant.
In areas exposed to direct sunlight, such as balconies and bay windows, it is recommended to use Sikadec High Polyurethane Color Sand Sealant. The pure polyurethane formula offers excellent resistance to yellowing.
The third-party report number is JCWT20260013572, based on inspection standards GB/T 23983-2009 and GB/T 1766-2008. After 168 hours of fluorescent ultraviolet aging tests according to GB/T 23983-2009, the color change grade is ≤0 level.
Of course, Sikadec High also offers different yellow resistance grade sealants to meet the specific sealant needs of various spaces.
For areas with no strong sunlight and general lighting, hydrogen-based sealant can be chosen; for spaces that are not exposed to sunlight at all, epoxy sealant is very suitable. Homeowners can flexibly choose the right sealant based on the actual lighting conditions of their space.
