| Use advice for data set | Scope: This is a manufacturer-individualised 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 products 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 the 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: Faade sealants Silicone-based products are used for the elastic sealing of joints. The areas of application for faade 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. | ||

| General comment on data set | EGOSILICONEs based on acetate (EGOSILICON 100, EGOSILICON 110, EGOSILICON 111, EGOSILICON 120, EGOSILICON 151) 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. EGOSILICONEs fulfil key functions. Ingress of moisture into the structure via the joints is prevented by EGOSILICONs. With the use of EGOSILICONEs, 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). | ||

| Technology description including background system | Silicone-based products, group 2 with a Volatile Organic Compound (VOC) content ≤2 % (VOC definition according to Decopaint Directive) are manufactured from reactive siloxane and so-called silicone oil, optionally by using fillers, extenders, colour pigments, cross-linkers, bonding agents and catalysts. For most of the applications the products are formulated as moisture-reactive one-component systems; for industrial applications there are also two-component systems available. They permanently and elastically seal joints planned for the building. Silicone-based products fulfil key functions. Ingress of moisture into the structure via the joints is prevented by joint sealants. With the use of silicone-based products, the fitness for use of the building and the service life are decisively extended. According to the Model EPD system (IBU) and the guideline and the substance list (available for members of the trade associations FEICA, EFCC, IVK and DBC), the environmental impacts of the substances are condensed to a single score; the single score of a formulation is calculated based on the single score of the substances. The products are grouped according to their single score (group 1 to 3), the formulation displaying the highest environmental impacts was used as a representative product for calculating the Life Cycle Assessment results (worst-case approach). Technical data: The density of the products is between 1,00 and 1,30 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 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). | ||
