Benefits Excellent weathering characteristics, including resistance to ozone, UV radiation and temperature extremes Joint movement capability +/- 50% Conforms to ISO 11600-F&G-25LM and also meets ISO specification 9047 class 50% Designed for general glazing, and weather sealing in curtain wall & building facades Colours Grey | Brown | Black | Anthracite | Bronze Buff | Limestone | Stone | Translucent | White Technical Information Where to use Exterior Paintable No Sizes 310 ml, 600ml Application method Sealant Gun and Cartridge Application Surface Preparation Ensure that surfaces to be sealed are clean, dry, sound and grease-free. Clean non-porous surfaces with DOWSIL™ R-40 Universal Cleaner, and dry thoroughly with a clean, lint-free cloth before application of sealant. Porous substrates such as concrete, brickwork, mortar etc. must be mechanically cleaned of loose particles using a steel brush, sanding disc or any similiar means. Application Instructions Apply sealant to the desired area using a sealant gun. Once finished, the joint should be tooled within 5 minutes of application to ensure good adhesion. For an extensive list of application methods, please consult the Technical Data Sheet. Clean up Excess sealant may be cleaned off tools and non-porous surfaces whilst in an uncured state using DOWSIL™ R-40 Universal Cleaner. If sealant is misapplied to porous substrates, it should be left until it is just cured and then removed by peeling, cutting or other mechanical means. Care should be taken not to damage plastic or coated surfaces.

Application temperature: >15°C Shelf life: 1 year (at 20°C and 50% relative humidity) Flammability This product is made up from PVC foam coated on both sides with an adhesive. It has not been tested for flammability but can be considered self- extinguishing due to the nature of the components. However, it should be noted that any smoke created would be highly toxic and would emit Hydrogen Cyanide gas during and after burning. Note All Technical data is based on average values. By nature of its manufacture, all foam specifications can vary by 10%. Statements, technical information and recommendations contained herein are based on tests we believe to be reliable. The user shall determine the suitability of the product for his/her intended use and the User assumes all risk and liability whatsoever in connection herewith. Products are manufactured to rigid standards of quality. To date no known failures have occurred due to the premature ageing of this product.
