Ru��bo�d PSCarbolineProduc� Flow DiagramLife Cycle Module De�crip�io�� Primary data were collected for the 12 month period starting October 2022 and ending September 2023 to ensure technical, geographical and temporal the representativeness. The products in this study are manufactured at Carboline’s facilities in Green Bay (Wisconsin), Lake Charles (Louisiana), and Dayton (Nevada). The manufacturing process entails the addition of pre-weighted ingredients, followed by mixing in the correct sequence to create the desired products. Subsequently, Carboline packages and distributes the finished products to various distribution centers. The process involves the use of grid electricity, heat from natural gas combustion, an process water. Non hazardous waste consisting mainly of packaging material is sent to disposal or recycling. LCA Di�cu��io� Alloca�io� Procedure Product packaging was allocated by mass. Allocation 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 and section 5 of NSF International PCR for Architectural Coatings v.1. Volumetric allocation was applied to energy and water use at the facility level, as it represents the partition among selling units (in gallons). Carboline Global, Inc. provided total volume produced at each facility. Cu�-off Procedure No cut-off criteria are defined for this study. The system boundary was defined based on relevance to the goal of the study. For the processes within the system boundary, all available energy and material flow data have been included in the model. In cases where no matching life cycle inventories are available to represent a flow, proxy data have been applied based on conservative assumptions regarding environmental impacts. Da�a Quali�y Di�cu��io� Page 9 / 19

Ru��bo�d PSCarboline The quality of inventory data is evaluated based on several criteria, including precision, completeness, consistency, and representativeness. Precision and Completeness • Precision: 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: 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: Primary data were collected with a similar level of detail, while background data came from the ecoinvent v3.9.1 database. The modeling approach and other methodological choices were applied consistently throughout the model. Default values from the PCR were considered where there was unavailability of primary data, For example, the default waste transport distance was used for product disposal assessment. • Reproducibility: 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: Primary data were collected for the one-year period of October 2022 to September 2023 to ensure the representativeness of post-consumer content. Secondary data from the ecoinvent v3.9.1 database is typically representative of recent years. • Geographical: Primary data represent Carboline's production facilities in Green Bay (Wisconsin), Dayton (Nevada) and Lake Charles (Louisiana). Where applicable, differences in electric grid mix were considered using appropriate secondary data. The use of country-specific data ensures high geographical representativeness, and proxy data were only used when country-specific data were unavailable. • Technological: Both primary and secondary data were tailored to the specific technologies studied, ensuring high technological representativeness. Where no direct raw material information was available in the ecoinvent 3.9.1 database, proxies were identified and used. Page 10 / 19

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. 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 / 19

Ru��bo�d PSCarboline The manufacturing of Carboline's products involves the direct procurement of raw materials from suppliers. These materials are then transported to Carboline's manufacturing facilities in Green Bay, WI, Dayton, NV, and Lake Charles, LA where they are stored and mixed to produce the coatings. At the application site, coatings are spray or brush applied to various exterior steel structural components to add a protective barrier to the steel substrate. The use stage (stage 3) has a smaller contribution to the overall life cycle performance.. For the analysis, It was assumed that Carboline's coatings require one initial coating application and multiple recoats to achieve the recommended service life of 60 years, aligning with the building's life cycle. The results were presented per one square meter of covered and protected substrate at a recommended coating thickness. The greatest contribution can be found in the use and maintenance stage due to the effect of the required repaints that will multiply the contribution of the product and design & construction stages together with the product application by the required number of recoats. For one single recoat, production stage, has the highest impact across all impact categories due mainly to the manufacture and transport of raw material, with some contribution of the manufacturing stage. At the application site, coatings are spray or brush applied to various exterior steel structural components to add a protective barrier to the steel substrate. This activity has a smaller contribution to the overall life cycle performance. End-of-life impacts are generally limited because most of the product is assumed to be landfilled, although impacts accumulate at each successive recoating. Given that the raw materials used in product manufacturing have the most significant impact, there are opportunities to substitute these materials with alternatives that have a lower environmental impact or to work with supplies in order to reduce impact along the supply chain. 0%20%40%60%80%100% GWP-total ODP AP EP POCP Produc�io� (A1 - A3)Co���ruc�io� (A4 - A5)U�e (B1 - B7)E�d of Life (C1 - C4)Addi�io�al E�viro�me��al I�forma�io� Before using this product, it is recommended that the operator read and follow all caution statements on the product data sheet and on the SDS for this product, and personal protective equipment must be used as directed.
