SIKA Sika Boom XL expansive polyurethane foam - 400ml, designed to fill and caulk voids by injection, which hardens after extrusion. With excellent adhesion on most substrates, it allows additional mechanical fixing around door and window frames. and provides insulation against noise, cold and drafts. Advantages: Adheres to most substrates Insensitive to humidity variations after hardening Excellent thermal and acoustic insulation Extremely "head - down" after vigorous agitation Contains a non - detrimental propellant for the ozone layer Emissions in the indoor air (Decree No. 2011 - 321 of March 23, 2011): A + "very low emissions" Features: Density: 20 to 30 kg / m3 approx. (free - expanding polymerized foam) Application temperature: from + 5 ° C minimum to + 25 ° C Curing speed: Final drying after 24 hours at + 20 ° C and 50% RH Waiting time: 24h to +20 ° C and 50% RH Dry time: about 20 to 30 minutes at + 20 ° C and 50% RH. Packaging: 400ml Reference: 441444 Packaging: 1x SIKA Sika Boom XL Expanded Polyurethane Foam - 400ml. Comes in original packaging. Advice: Support: Substrates must be cohesive, sound and clean. Eliminate dust, laitance, grease, rust, and any product that may affect adhesion. Moisten supports by spraying tap water. Application: Prior to applying foam, protect from burrs, racks with removable masking tape and soil. Screw the extension hose onto the aerosol without forcing. Shake the aerosol vigorously for 30 seconds. Extrude the foam "upside down" by moderately squeezing the trigger. Immediately after use, clean the valve with acetone or Sika Boom Cleaner and clean the extension hose with Sika Boom Cleaner for a second time. Apply in layers up to 30 mm thick. Moisten by spraying tap water between the layers of extruded foam. Fill cavities 30% approx. of their total volume, because in case of excess, the strong expansion of the foam can cause significant overflows and dirt. In case of multiple extrusions, shake the aerosol again before each extrusion. Uncured burrs can be cleaned immediately with acetone or Sika Boom Cleaner, avoiding contact with the foam layer, The consistency of the foam is suitable for filling vertical joints up to 5 cm wide. Joints wider than 5 cm should be filled in successive layers applied on the previous completely polymerized. After polymerization, cut the foam with a cutter if necessary In the case of exterior joinery, make an exterior cladding with cement mortar in 10mm thick and then apply a sealant seal of the Sika range on a Sika JOINTS FIT of section adapted to ensure watertightness . The final strength is obtained after complete polymerization. Can be painted after 24 hours of drying at + 20 ° C: preliminary test. Can be coated after 24 hours of drying at + 20 ° C with a mortar of cement or plaster. Use Sika products with care. Before use, please consult the manufacturer's product leaflet available on the sika.fr website.
