QMS-828 Single Component Neutral Dealcohol-Cured Building Weathering Sealant
Achieve professional-grade sealing with QMS-828, a medium modulus, durable sealant designed for building weathering. This single-component sealant offers high adhesion and weather resistance on most building materials.
Applicable Materials: QMS-828 is suitable for use on mirrors, coated glass, ceramics, glass fibers, galvanized metal surfaces, pottery products, most plastic panels, non-oily wood, and anodized or painted aluminum profiles.
Usage Restrictions: Avoid using QMS-828 in engineering applications where the construction substrate's surface temperature exceeds 50°C. Ensure the sealant is not applied in an environment completely isolated from air before curing.
