Product description
GacoFlex S4200 White is a high-adhesion, solvent-free, single-component waterproof elastomeric moisture-curing silicone coating that does not require a primer over most substrates. S4200 is ideal for use as a maintenance coating system over metal roofs, weathered single ply membranes, and polyurethane foam roofs (including GacoRoofFoam). S4200 is ideal for use over aged SBS, APP, and built-up roofing, where the membrane surface is in sound condition but requires a renewal of the membrane surface due to the normal effects of use and aging. S4200 provides a seamless, weather-tight seal that protects the roofing substrate from degradation caused by UV, water, and other normal weathering hazards. A roof coated with S4200 is ideal for use as part of a rainwater catchment system.
Application involves cleaning and preparing the roof surface, then applying the coating using rollers, brushes, or sprayers in one or more layers. Once cured, the coating forms a flexible, weather-resistant membrane that adheres tightly to the substrate.
Interpretation
Based on the results and study assumptions, methods, and data, the cradle-to-gate impacts (A1–A3) for the product represent approximately 50% of the total Global Warming Potential (GWP). The remaining impacts occur in later life-cycle stages.
LCIA results are relative expressions and do not predict impacts on category endpoints, the exceeding of thresholds, safety margins or risks. EPDs are comparable only when they follow the same PCR, functional unit and system boundary. The full EPD (PDF) contains the methodology, scenario assumptions and verification statement.
