Product description
Stonclad UT is a dense, liquid-rich, self-priming, textured, four-component, notch- trowel- applied, polyurethane mortar system. Stonclad UT consists of a urethane-urea binder, pigments and graded quartz aggregates. Stonclad UT is a high-impact resistant mortar which exhibits excellent abrasion, thermal shock, thermal cycling and chemical-resistant characteristics, making it ideal for the food and beverage industry as well as any other applications requiring these properties.
Interpretation
Raw materials are sourced from suppliers, transported to manufacturing facilities, and mixed to produce products. The product stage (A1-A3) has the highest environmental impact, especially due to raw material production and energy use.. End-of-life impacts are relatively low, as products are assumed to be landfilled with building demolition waste. However, this stage (modules C1-C4) should be considered when using the results of the product stage (modules A1-A3). The manufacturer should explore lower-impact raw materials and work with suppliers using sustainable methods to enhance product sustainability.
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.
