Product description

GacoFlex S2100 White Cleanable Solvent-Free Silicone Coating is a high-solids 100% silicone coating that resists dirt pick-up even after years of exposure, thereby maintaining significantly higher whiteness and solar reflectivity than other silicone coatings. It is highly cleanable, and if necessary, can easily be cleaned with GacoFlex GacoWash Concentrated Cleaner. Improved rheology provides better film build on high spots and over granular or uneven surfaces. GacoFlex S2100 contains 37% recycled content and does not contain crystalline silica. Like all GacoFlex silicone roof coatings, it withstands permanent ponding water. Use GacoFlex S2100 as a maintenance coating system over existing elastomeric roof coatings, metal roofs, smooth built-up roofing, mineral cap sheets, modified bitumen (APP and SBS) and weathered single ply membranes where the substrate is in sound condition, but requires a renewal of the surface due to the normal effects of aging and use. GacoFlex S2100 is ideal for use over sprayed-in-place polyurethane foam roofing, such as GacoRoofFoam, concrete and plywood decking (when properly applied over an approved base coat). When properly applied, the S2100 coating system provides a seamless weather-tight seal that protects the substrate from degradation caused by ultraviolet light, water, and other normal weathering hazards.

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.
