A range of self-adhesive silicone fin seals to complement Zero teardrop seals 188S, 488S and 388S. The 1771S and 1772S shown below have been developed specifically as meeting stile seals in response to requests from steel door manufacturers to solve the problem of sealing meeting stiles of pairs of doors. With Tee fins at 90 degrees, both can be fitted to either the astragal or the leading edge on a pair of doors. The 1773S and 1777S have Tee fins at 75 degrees and can be used as perimeter seals fitting into the rebate across the head and down both sides of the frame. They are all supplied with double sided backed PSA (pressure sensitive adhesive) tape and are suitable for internal and external doors. These products are currently only available in black, although they may be available in dark bronze, white and grey depending on quantity.
FIRE AND SMOKE
These new fin seals will be tested or assessed to BS EN 1634-1 and BS EN 1634-3, but testing was incomplete when this catalogue went to print. Please contact us for a current data sheet with up to date information.
Manufactured from silicone which is flame resistant. Silicone seals have a good resistance to acid, oil, gasoline, animal/vegetable oils and water absorption. They also have excellent resistance to ultraviolet rays, sunlight ageing, oxidation, ozone, heat ageing, heat, cold and flame.
The adhesive on these fin seals will have the best end use high and low temperature adhesion if installed to a clean dry frame between 18°C - 35°C. For proper performance do not install on a frame at less than 10°C or more than 35°C. Ensure all materials are at the same temperature before bonding. These seals have a functional operating range between -40°C and +80°C. Rebound is excellent when both hot and cold.
The surfaces should be clean, dry and free of dust, grease and oil before the installation process begins. If cleaning is necessary only use a clean cloth and a solvent that is compatible with the materials, such as isopropanol (isopropyl alcohol or IPA), ethanol or methanol (methylated or surgical spirits). Make sure to check for any impediments (dust, dirt, oil, grease, etc) or loose paint and remove them from the surface area. The surface must be completely dry before the installation process begins. We recommend that gasketing be installed after the doors and frames have been painted to the final finish and the paint has dried. Paints with plasticisers should be avoided as these can damage the adhesive layer. Paint should be dry and uniform (quick drying primers are not recommended). For application to timber frames, the painted or finished surface must be non-porous and smooth. DO NOT STRETCH THE SEAL DURING INSTALLATION. The adhesive is designed to gradually set to a high peel strength so that immediate removal and resetting can be done if an error is made in the initial placement. Do not reset after one hour. Full set is reached in approximately 24 hours.
