Product description

Stongard MR is a fluid applied flooring system which falls under the MasterFormat classification 09 67 00.00 Finishes: Fluid-Applied Flooring. It consists of 3-layers: a primer (Primer 150), a polyurethane elastomeric membrane (Stonproof ME7) and a top coat (Stonkote HT4).

Individual component descriptions:

Primer 150 is a two-component, epoxy based primer. It is applied to a properly prepared substrate prior to the application of the appropriate Stonhard overlayment. The use of Primer 150 ensures a secure bond between the substrate and the overlayment, as well as provide protection from moisture that is present in green concrete.

Stonproof ME7 is a two-component polyurethane elastomeric membrane used for positive-side waterproofing applications.

Stonkote HT4 is a two-component, 100% solids, epoxy coating. It is specifically formulated to provide outstanding protection from a wide range of chemicals while increasing abrasion resistance and cleanability. Stonkote HT4 is easily applied and hardens to an attractive gloss finish.

Interpretation

The main EPD results are given in the EPD report. A1 process accounted for as much as 2.51 kgCO2e/kg of Stongard MR product, while the Primer 150 components accounted for nearly 0.87 kgCO2e/kg of Stongard MR product. Overall the A1-A3 GWP100-Total was 3.14 kgCO2e/kg of Stongard MR product. The A5 impact was very low compared to the manufacturing impact. Although C3 and C4 phases corresponding to the waste processing and disposal, respectively, are out of the boundaries of this LCA, it is investigated the amount of biogenic carbon that would be released during these phases. Under the reality of taking the product mixed with other building and construction materials (such as concrete), which is the classic use of this product, it is assumed that the product will end-up landfilled in a sanitary landfill stick together to large concrete chunks without the possibility of separation and specific recovery or treatment of MR. Since the biogenic content of Stongard MR is mixed with physically stable constituents and resins, which indeed allow lifespans accordingly long for the building and construction sector (>50-100 years), it is not expected a release of biogenic carbon under landfilling conditions, less within a period of 100 years since product manufacturing, which would account within the global warming potential at 100 years (GWP100) indicator. Biogenic carbon content of this product is expected to behave as biomass captured within fossil amber resins, which remain sequestered during long periods of time, frequently millions of years. Thus, the biogenic carbon released during phases C3 and C4 is expected to be extremely low, potentially zero if the product is considered a waste after more than 100 years since manufacturing.

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.
