These data should not be interpreted as the conformity criteria. The conformity criteria are given in manufacturer’s specifications. Two component polysulphide based outer sealant for insulating glass units TENAGLASS -PS EN ® IMPORTANT FEATURES APPLICATION CURING MECHANISM Sealant components A and B react with each other. Component B acts as a catalyst promoting the build-up of the backbone consisting of polymer of component A. It is essential to apply component A of TENAGLASS®-PS EN only in mixture with component B of TENAGLASS®-PS EN. Avoid contamination of TENAGLASS®-PS EN with previously used sealants. The deviations of component B quantity ± 20 % from the nominal quantity will not affect the IGU production control parameters remarkably. Excess quantity of component B will speed up the initial curing but can seriously affect the adhesive properties. Insufficient quantity of component B will slow down the curing speed and will lower the mechanical strength. Any deviations from nominal mixing ratio can affect the permeability and durability of the edge seal. Keep in mind that the certificates for all two component sealants refer for nominal mixing ratio only. SURFACE PREPARATION Surfaces of the cavity have to be sound, clean and dry. Delete glass coating at the edge of glass pane unless indicated otherwise by the glass supplier. TEMPERATURE INFLUENCE In general, the rate of chemical reaction doubles for every 10 °C rise in temperature. As a consequence, with temperature decrease the pot life increases and the build-up of sealant hardness and adhesion slows down. During the hot or cold weather make sure that the build-up of the hardness and the adhesion is still acceptable for the production speed, and the pot life is still long enough to maintain the machinery in good condition. Temperature also influences the flow properties of the components and the mixed sealant. Drop of temperature rises the viscosity of the compounds and higher pumping capacity of the dispensing device is required. COMPATIBILITY Before the application of the sealant always perform the tests to make sure that all materials having direct or indirect contact are compatible and do not change or affect the properties of each other. This applies especially to IGU inner sealants and, if applicable, adhesives for direct glazing and weatherproofing gaskets and sealants. TENAGLASS®-PS EN is compatible with IGU inner sealants TENAGLASS®, glazing adhesives TENABOND® and weatherproofing sealants TENALUX®. For the use of TENAGLASS®-PS EN in combination with other sealants and adhesives the manufacturer’s approval is required. If other polymeric constituents can be influenced by this sealant, please refer to the respective material suppliers. In case of doubt always choose the design of the glazed structure where the sealant is in contact only with the tested materials, i.e., avoid any direct contact between IGU outer sealant and any other constituent containing the migrating substances. MIXING Use automated or hand operated IGU production machinery for mixing and application of sealant. Avoid contamination of component B with moisture. Always follow advised mixing ratio given on packaging to obtain the best results. For machine adjustment check the mix properties in mixing ratio range ± 20 % from the nominal quantity of component B. Apply methods for mixing quality control in accordance with EN 1279-6 or similar. EQUIPMENT CLEANING Please refer to user manual of dispensing equipment manufacturer as well as special instructions for TENAGLASS®-PS EN application. HEALTH AND SAFETY MEASURES Please refer to information given in safety data sheet for TENAGLASS®-PS EN. Follow actual legislation requirements in the place of product application. Always use individual protection measures when working with sealant. Avoid the contact of uncured sealant with skin. PROTECTION OF ENVIRONMENT Waste of sealant and materials contaminated by it have to be collected and turned to waste deposit area. Contact your local or regional authorities for disposal options.

It is more reliable to choose adhesive bond with rigid substrates, i.e., whenever possible, bond the face of glass pane to the frame structure.
