Structural Silicone (XYT928) vs Weatherproof Silicone (XYT926)

• Structural Glazing Sealant (XYT928): High tensile modulus (0.90 MPa) engineered to bear structural wind loads, seismic forces, and dead load weight. Must never be substituted with standard caulk.
• Weatherproofing Sealant (XYT926): Low-to-medium modulus (0.70 MPa, ±25% movement) designed to seal exterior joints against rainwater and air leakage without stressing the substrate.

Safety Engineering Note: CHEMPU provides project-specific structural bite calculations and adhesion testing on actual glass/metal samples before project commencement.
