Comparison of the environmental performance of products usingEPD information shall be based on the product’s use and impacts at the building level, and therefore EPDs may not be used for comparability purposes whennot considering the whole building life cycle. EPD comparability is only possible when all stages of a life cycle have been considered. However, variations anddeviations are possible. Example of variations: Different LCA software and background LCI datasets may lead to differences results for upstream ordownstream of the life cycle stages declared.

Series 257 minimizes the potential for lap marks and roller lineswhen used in large flooring applications. It can be used as a two coat thin-film system or as a clear or pigmented finish coat over systems built using epoxyor polyurethane modified concrete floor toppings that have been fully broadcast with aggregate, colored quartz or colored flake. Series 257 will provideprotection against impact, abrasion and mild chemicals, has excellent gloss and color retention, and resistance to yellowing.

A background LCI database is the databaseused to model generic or non-specific data.Data QualitySeries 257 ExcellaThane SSTnemecPage 6 / 17

The quality of inventory data is evaluated based on several criteria, including precision, completeness, consistency, and representativeness. Based on thesefactors, 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 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 inline with the PCR requirements, such as personnel impacts, R&D activities, business travel, secondary packaging, point of sale infrastructure, and thecoating 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, withother databases used only if necessary or more representative. The modeling approach and other methodological choices were applied consistentlythroughout the model.Reproducibility (Very Good): This study ensures reproducibility by providing comprehensive disclosure of input-output data, dataset choices, andmodeling approaches. A knowledgeable third party should be able to approximate the results using the same data and modeling methods.Representativeness (Good):Temporal: Primary data were collected for the 12 month period of the 2024 calendar year to ensure the representativeness of post-consumer content.Secondary data from the ecoinvent v3 database is typically representative of recent years.Geographical: Primary data represents Tnemec's production facilities in North Kansas City, MO, and Baltimore, MD. We considered regional differencesin electric grid mix using appropriate secondary data. Country-specific data ensures high geographical representativeness, with proxy data used onlywhen necessary.Technological (Good): Both primary and secondary data were tailored to the specific technologies studied, ensuring high technologicalrepresentativeness.Life Cycle Module DescriptionThe 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 wastematerials, 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 theflooring substrate at the site. Impacts include VOC emissions from curing, product packaging disposal, and upstream production stage impacts associatedwith 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 afterinstallation and continues until the product reaches its end-of-life stage. Impacts include all cleaning and necessary recoating events during the servicelifetime. End-of-life (C1-C4) was modeled according to PCR descriptions (solvent-based coatings are incinerated for energy recovery and water-basedcoatings are sent to landfill).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 useand VOC emissions at the Kansas City, MO, factory were allocated by mass. Overhead burdens (building heating and corporate use consumption) wereexcluded using a square footage factor, that benchmarked and validated with process engineering models of resinous floor coatings production. The processSeries 257 ExcellaThane SSTnemecPage 7 / 17

do not consume process water or generate wastewater. Solid waste was estimated using packaging masses and material losses and allocated following thepolluter 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 availableenergy and material flow data have been included in the model. Exclusions allowed by the PCR such as secondary and tertiary packaging, wereimplemented, as well as overhead burdens such as building heating and corporate office consumption.Renewable ElectricityEnergy Attribute Certificates (EACs) such asRenewable Energy Certificates (RECs) or PowerPurchase Agreements (PPAs) are included in thebaseline reported results:NoSeries 257 ExcellaThane SSTnemecPage 8 / 17

InterpretationRaw materials are sourced from suppliers, transported to manufacturing facilities, and mixed to produce products. The product stage (A1-A3) has thehighest environmental impact, especially due to raw material production and energy use, impact amplified in the use phase (B4) from recoatings. TheMarket scenario shows higher use-phase impacts due to a shorter estimated service life (ESL).End-of-life impacts are relatively low, as products areassumed to be landfilled with building demolition waste. Switching to renewable energy is advised for products with high manufacturing energydemands.
