1. Dry Glazing System Materials - Residential and Commercial Applications - co-extruded profile - coated / lubricated gasket - standard gasket - all frame types - PVC-U dry glazing - EPDM - TPE - silicone based rubber - foam e.g. polypropylene - vinyl - glazing tape When glazing Pilkington Activ™, the strongly preferred option is to use a co-extruded gasket or a dry rubber gasket. Only if the use of a dry gasket or co-extruded system is not possible should a rubber gasket lubricated with glycerol or alternative silicone free / siloxane free lubricant be used. If all of the above options are unavailable...

■ Note: Lubricated/Coated samples sent for testing showed little or no hydrophobic leaching and therefore passed tests. Due to the nature of these lubricants they must be applied by the manufacturer and be fully dried prior to sue. Under no circumstances should additional lubricant be applied on site.

SCG-TEC based sealants have been specifically developed for use with Self Cleaning Glass. These products offer improved UV resistance and durability compared with MS Polymer based sealants and are certified to external standards (e.g. ISO 11600, further details are available from the individual sealant suppliers). As with all approved sealants these materials have been tested for compatibility with Pilkington Activ™. These sealants are suitable for both residential and commercial applications. As with all sealant applications, checks with the sealant supplier that the material is suitable for...

2.2 Wet Glazing Sealants - MS/Hybrid Technology MS Polymer / Hybrid based sealants have been tested for compatibility with Pilkington Activ™. Suitability of these sealants for the intended application must be discussed with the individual manufacturer.

Note - Glass adhesives are not glazing sealants

Please Note: If there is a straightforward pathway for water run-off between the silicone caulking and the Pilkington Activ™ surface, the caulking material should NOT be silicone. Alternatives include MS Polymers and polyurethanes. The product listed below has been tested and is compatible with Pilkington Activ™ as a sealant to be used between window frame and brickwork, concrete or cladding material. To mount the glass into a window frame, other sealant types are available. Further details on application suitability is available from the supplier.

3.0 Commercial Glazing Systems

All of the lubricated gaskets have been tested for compatibility with Pilkington Activ™ in the vertical orientation. Some of the gaskets that are lubricated with a silicone emulsion have occasionally shown very low levels of leaching (<2 cm). However, due to the longer residence time of water on the gasket, there is the potential for an increased level of leaching if these same gaskets used in sloped glazing. Under no circumstances should extra lubricant be used during installation. Please check with your supplier to ensure gaskets lubricated with silicone emulsion are NOT used in sloped installations....

In addition to the above specific systems, there are a number of suppliers who can supply nonsilicone based gaskets, if they are specifically requested. This service is available from the German offices but can be discussed with your local representative. Please put on the order "Non-silicone gaskets required for use with Pilkington Activ™." These suppliers are listed below, along with their contact phone number in Germany.

Protective film Use is optional. If a film is used, any residual adhesive should be cleaned off, first with hot soapy water, secondly with a solvent wash for more stubborn adhesive, but never with an abrasive substance or cloth.

4.4 List of Approved Cleaning Agents

The use of silicone removers / abrasive cleaners on Pilkington Activ™ is considered as a remedial action which should only be undertaken after consultation with the NSG Group Technical Advisory Service. Due to the nature of these materials, work should only be undertaken after reading the manufacturers' relevant safety literature. NSG Group cannot guarantee the effectiveness of the treatment or the effect the treatment will have on the coating as this will be severely affected by factors outside NSG Group's control, for example the nature and amount of the deposit. The use of silicone eaters...
