Product description
Stonclad UR is a four-component, trowel applied, polyurethane mortar system. Stonclad UR consists of a urethane-urea binder, pigments, and graded quartz aggregates. Stonclad UR can be applied at thickness ranging from 1/8in/3 mm to 1/4in/6 mm depending on application requirements. Stonclad UR 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, impact amplified in the use phase (B4) from recoatings.The Market scenario shows higher use-phase impacts due to a shorter estimatedservice life (ESL).End-of-life impacts are relatively low, as products are assumed to be landfilled with building demolition waste.Switching to renewable energy is advised for products with high manufacturing energy demands.The manufacturer should explore lower-impact raw materials and work with suppliers using sustainable methods or renewable energy 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.
