| Use advice for data set | Scope: This is a manufacturerindividualised EPD based on model declaration 'Silicone-based products, group 2' (EPD-DBC-20220180-IBF1-EN) from Deutsche Bauchemie e.V. (DBC), European Federation for Construction Chemicals (EFCC), Association of the European Adhesive and Sealant Industry (FEICA) and Industrieverband Klebstoffe e.V. (IVK) in which the product exhibiting the highest environmental impact in a particular group was selected from the group to calculate the LCA. This verified EPD entitles the holder to bear the symbol of the Institut Bauen und Umwelt e.V.. It exclusively applies to products produced in Europe and applies to a period of five years from the date of issue. This EPD may be used by members of DBC, EFCC, FEICA and IVK and their members provided. It has been proven that the respective product can be represented by this EPD. System boundary: Modules A1, A2 and A3 are taken into consideration in the LCA: - A1 Production of preliminary products - A2 Transport to the plant - A3 Production incl. provision of energy, production of packaging as well as auxiliaries and consumables and waste treatment - A4 Transport to site - A5 Installation, product applied into the building during A5 phase operations and packaging disposal. This stage considers VOC emissions during the installation phase. The declared product contain substances in(to) the formulation that directly emit as VOC. VOCs are even generated by a chemical reaction that is occurring during this phase. The end of life for the packaging material considered is described below: -Incineration, for materials like plastic, paper and wood. -C1-C2-C3-D The building deconstruction (demolition process) takes place in the C1 module which considers energy generation and consumption of diesel and all the emissions connected with the fuel-burning process to run the machines. After the demolition, the product is transported to the end-of-life processing (C2 module) where all the impacts related to the transport processes are considered. For precautionary principle and as a worst-case scenario, thermal treatment is the only end-of-life scenario considered. This is modelled by the incineration process (module C3) where the product ends its life cycle. Module D accounts for potential benefits that are beyond the defined system boundaries. Credits are generated during the incineration of wastes and related electricity produced that are occurring in the A5 module. | ||
| Technical purpose of product or process | Module 1: Façade sealants Silicone-based products are used for the elastic sealing of joints. The areas of applicationfor façade sealants include expansion joints (movement joints) and/or connection joints already existing in exterior walls and on window and door frames (including the inside section). All these sealants fulfil key functions of the building. Module 2: Sealants for glazing Silicone-based products are used for the elastic sealing of joints which may be subject to movement. Sealants for glazing are used in the following areas: (i)Glass to glass (ii)Glass to frame (iii)Glass to porous substrates Module 3: Sanitary sealants The areas of application for silicone-based sanitary sealants are joints in sanitary areas and kitchens. Joints sealed using sanitary sealants comprise connection joints between sanitary furnishings and the wall, connection joints between the floor and wall or movement joints across surfaces, for example. Module 4: Sealants for pedestrian walkways The areas of application for silicone-based sealants for pedestrian walkways are floor joints designed for pedestrian walkways, public areas, movement joints between concrete slabs, areas with pedestrian load, areas used with trolleys, walkable floors, balconies, terraces, warehouses. | ||

| General comment on data set | Neutral curing EGOSILICONs (EGOSILICON 300 [TRANSPARENT] ▪ EGOSILICON 333 ▪ EGOSILICON 351 ▪ EGOSILICON 352 ▪ EGOSILICON 360 ▪ EGOSILICON 365) are manufactured from reactive siloxane, colour pigments, cross-linkers, bonding agents, catalysts and optionally by using fillers and so-called silicone oil. The products are formulated as moisture-reactive one-component systems. They permanently and elastically seal joints planned for the building. EGOSILICONs fulfil key functions. Ingress of moisture into the structure via the joints is prevented by EGOSILICONs. With the use of EGOSILICONs, the fitness for use of the building and the service life are decisively extended. The product displaying the highest environmental impacts was used as a representative product for calculating the Life Cycle Assessment results (worst-case approach). For the placing on the market in the European Union/European Free Trade Association (EU/EFTA) with the exception of Switzerland) products falling under the Regulation (EU) No 305/2011 (CPR) need a Declaration of Performance taking into consideration either the relevant harmonised European standard or the European Technical Assessment and the CE marking. For the application and use of the products the respective national provisions apply. Neutral curing EGOSILICONs (EGOSILICON 300 [TRANSPARENT] ▪ EGOSILICON 333 ▪ EGOSILICON 351 ▪ EGOSILICON 352 ▪ EGOSILICON 360 ▪ EGOSILICON 365) fulfil the requirements of the application modules listed below and have the corresponding declaration of performance. | ||

| Technology description including background system | Silicone-based products, group 2 with a volatile organic compound (VOC) content ≤2 % (VOC definition according to the Decopaint Directive) are manufactured from reactive siloxane and so-called silicone oil, possibly using fillers, extenders, color pigments, crosslinkers, binders and catalysts. For most applications, the products are formulated as moisture-reactive one-component systems; two-component systems are also available for industrial applications. They provide a durable and elastic seal for the joints planned on the building site. Silicone-based products fulfill important functions. Joint sealants prevent moisture from penetrating the building via the joints. The use of silicone-based products significantly extends the serviceability of the building and its service life. In accordance with the model EPD system (IBU) and the guidelines and list of substances (available to members of the FEICA, EFCC, IVK and DBC trade associations), the environmental effects of the substances are summarized in a single score; the single score of a formulation is calculated from the single score of the substances. The products are divided into groups according to their single score (groups 1 to 3), with the formulation with the highest environmental impact being used as the representative product for calculating the LCA results (worst-case approach). Technical data: The density of the products is between 1,00 and 1,10 g/cm, other relevant technical data can be found in the manufacturers technical documentation. Module 1: Faade sealants The minimum requirements on water and airtightness as per Table ZA.1 of EN 15651-1 apply: see table Module 2: Sealants for glazing The minimum requirements on water and airtightness as per Table ZA.1 of EN 15651- 2 apply: see table Module 3: Sanitary sealants The minimum requirements on water and airtightness as per Table ZA.1 of EN 15651-3 apply: see table Module 4: Sealants for pedestrian walkways The minimum requirements on water and airtightness as per Table ZA.1 of EN 15651-4 apply: see table Declared unit: This EPD refers to the declared unit of 1 kg of silicone-based product, group 2; applied into the building with a density of 1.0 - 1.5 g/cm in accordance with the IBU PCR part B for construction sealant. The results of the Life Cycle Assessment provided in this declaration have been selected from the product with the highest environmental impact (worst-case scenario). Depending on the application, a corresponding conversion factor such as the density to convert volumetric use to mass must be taken into consideration. The Declaration type is according to EN 15804: Cradle to gate with options, modules C1–C3, and module D (A1–A3, C, D) and additional modules (A4-A5). | ||
