Product description

Stonchem Epoxy Primer is a two-component, pigmented epoxy based priming system. It is applied to a properly prepared surface prior to the application of the appropriate Stonhard overlayment. The use of Stonchem Epoxy Primer ensures a secure bond between the substrate and the overlayment, reduces absorption of the overlayments liquids (epoxy resin/curing agent) and makes the application of the overlayment easier.

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.
