However, differences in certain assumptions, data quality, and variability between LCA data sets may still exist. As such, caution should be exercised when evaluating EPDs from different manufacturers or programs, as the EPD results may not be entirely comparable. Any EPD comparison must be carried out at the construction works level per ISO 21930:2017 guidelines. The results of this EPD reflect an average performance by the product and its actual impacts may vary on a case-to-case basis.Page 2 / 20

Desco 6500Desco CoatingsSoftware and DatabaseLCA Software:SimaPro v. 9.5LCI Foreground Database(s):Ecoinvent v. 3.9.1Cut-off by ClassificationLCI Background Database(s):Ecoinvent v. 3.9.1Cut-off by ClassificationA foreground LCI database is the database used to model the primary, site-specific data collected for this EPD. A background LCI database is the database used to model generic or non-specific data.Data QualityThe quality of inventory data is evaluated based on several criteria, including precision, completeness, consistency, and representativeness. The analysis follows the data quality level and criteria of the UN Environment Global Guidance on LCA database development. Based on these factors, the overall data quality is rated as "Good".Precision and completeness:• Precision (Very Good): The inventory data used in this study were either directly measured, calculated, or estimated based on primary data sources, ensuring high precision. Background data from Ecoinvent v3.9.1 database also has documented precision to the extent available.• Completeness (Very Good): The product system's mass balance and inventory completeness were thoroughly checked. Some exclusions were made in line with the PCR requirements, such as personnel impacts, R&D activities, business travel, secondary packaging, point of sale infrastructure, and the coating applicator. However, no data was intentionally omitted.Consistency and reproducibility:• Consistency (Good): Primary data were collected with a similar level of detail, while background data primarily came from the Ecoinvent database, with other databases used only if necessary or more representative. The modeling approach and other methodological choices were applied consistently throughout the model.• Reproducibility (Very Good): This study ensures reproducibility by providing comprehensive disclosure of input-output data, dataset choices, and modeling approaches. A knowledgeable third party should be able to approximate the results using the same data and modeling methods.Representativeness:• Temporal (Good): Primary data were collected for the totality of the reference study period to ensure the representativeness. Secondary data from the Ecoinvent v3.9.1 database is typically representative of recent years, a detailed data quality analysis following ISO 21930 was performed on the background database and is available at request.• Geographical (Good): Primary data represents Desco's production facilities in Batavia, OH, and Phoenix, AZ. Regional differences in electric grid mix were considered using appropriate secondary data. Country-specific data ensures high geographical representativeness, with proxy data used only when necessary.• Technological (Good): Both primary and secondary data were tailored to the specific technologies studied, ensuring high technological representativeness.Life Cycle Module DescriptionsThe production stage (A1-A3) starts with the reception of raw materials, typically in the form of chemical packages (cans, plastic pails, plastic drums, supersacks, bags, etc). Next, the raw materials are mixed to form resins and additives. Non-hazardous waste, consisting mainly of packaging waste materials, is sent for disposal, incineration, and/or recycling. Hazardous waste consists of manufacturing product losses. The construction stage (A4-A5) starts with the packaged and finished coating leaving the production site and ends with the finished coating being installed/applied and cured onto the flooring substrate at the site. Impacts include VOC emissions from curing, product packaging disposal, and upstream production stage impacts associated with the ~2% of the wet mass of the coating that remains unused. The use stage (B1-B7) begins after the resinous floor coating has fully cured after installation and continues until the product reaches its end-of-life stage. Impacts include all cleaning and necessary recoating events during the service lifetime. End-of-life (C1-C4) was modeled according to PCR descriptions. Product at the end of life is sent to landfill. Unused solvent-based coatings are incinerated for energy recovery and water-based coatings are sent to landfill. Finally, impacts beyond system boundaries (Module D) include energy received from unused product incineration (C3) and the recycling of packaging materials (A5).Page 8 / 20

Desco 6500Desco CoatingsService LifetimeRegarding the Service Lifetime listed under the sections of Product Information, Production Specification and Replacement (B4), please be aware that this product is not applied as a stand-alone flooring product. It is a part of a multi-component resinous flooring system. The service life is based on typical flooring systems selected from several general categories by referring to the PCR, including the following examples: thin-film coating, slurry, or mortar. Service life is also based on the flooring application type, e.g., commercial versus industrial.LCA DiscussionAllocation ProcedureAllocation of co-products was avoided, to the extent it was possible, based on the guidance given in ISO 14044:2006, 4.3., in ISO 21930:2017. Energy use, water consumption, wastewaater treatment and VOC emissions at the Batavia, OH and Phoenix, AZ facilities were allocated by mass. Solid waste was estimated using packaging masses and material losses and allocated following the polluter pays principle.Cut-off ProcedureThe system boundary was defined based on relevance to the goal of the study. For the raw material (A1) and process related inputs (A3), all available energy and material flow data have been included in the model. Exclusions allowed by the PCR such as secondary and tertiary packaging, were implemented.Renewable ElectricityEnergy Attribute Certificates (EACs) such as Re-newable Energy Certificates (RECs) or Power Pur-chase Agreements (PPAs) are included in the baseline reported results:NoScenariosMaintenance (B2)B2 ModuleMaintenance Cycle:18.33 Cycles/RSL220 Cycles/ESLNet Fresh Water Consumption Specified by Water Source and Fate:0.83 m3Ancillary Materials Specified by Type:1.32 kgMaintenance Process Information:As per the PCR, "220 cleaning events shall be reported in module B2 of the LCA and subsequent EPD".

Comparisons may be made between product-specific or industry average EPDs at the time of product purchase when product performance and specifications have been established and serve as a functional unit for comparison. Environmental impact results shall be converted to a functional unit basis before any comparison is attempted.Any comparison of EPDs shall be subject to the requirements of ISO 21930 or EN 15804. EPDs are not comparative assertions and are either not comparable or have limited comparability when they have different system boundaries, are based on different product category rules or are missing relevant environmental impacts. Such comparison can be inaccurate, and could lead to erroneous selection of materials or products which are higher-impact, at least in some impact categories.Page 12 / 20

Desco 6500Desco CoatingsInterpretationRaw materials are sourced from suppliers, transported to manufacturing facilities, and mixed to produce products. The product stage (A1-A3) drives the environmental impact, due to raw material production and energy use. This impacts is amplified in the use phase due to recoatings, making B4 the largest contributor to the overall impact. Market and Technical service life scenarios differ depending on assumed estimated service life (ESL), with lower impacts for longer-lived products. Those scenarios are constructed using PCR prescriptions that are highly conservative, as they assumed the replacement of the full coating system. 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.0%20%40%60%80%100%GWP-totalODPAPEPPOCPProduction (A1 - A3)Construction (A4 - A5)Use (B1 - B7)End of Life (C1 - C4)Additional Environmental InformationNoneReferences• PARQ.
