Description

SIKA Sika Boom 102 Combi Expandable Polyurethane foam - 500ml, a 2 - in - 1 foam insulation used to cushion, seal and insulate against cold, noise and drafts. This expansive foam extrudes "upside down" and has good adhesion to concrete, cement mortar, cement fiber, terra cotta, plaster, tile, wood for maximum versatility. Advantages: Good adhesion on many supports Good elastic recovery Can limit the forces transmitted to the support Very good acoustic and thermal insulation A "head - down" extrusion Designed with a non - detrimental propellant gas for the ozone layer Ideal for the complement of mechanical fastening and insulation around door and window frames, filling cavities in: walls, partitions, pipe passages and pipes Characteristics: Density: 20 +/ - 5 kg / m3 approx Application temperature: + 10 ° C minimum at + 25 ° C maximum Curing speed: Final drying after 24 hours at + 23 ° C and 50% RH. Dry time to touch: 18 to 26 minutes approx. at + 23 ° C and 50% RH Fire resistance: B3 (cured polymerized foam) Reuse: Reusable 1 month if the hose is folded Packaging: 500ml Reference: 521224 Packaging: Comes in its original packaging Advice: Support: Supports must be cohesive, healthy and clean. Eliminate dust, laitance, grease, rust and any product that may affect adhesion. Moisten supports by spraying tap water. Application: Shake the aerosol well for at least 20 seconds before use. Shake again after long periods of use. Moisten by spraying tap water on the supports and between 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. Apply in layers up to 30 mm thick. The consistency of the foam is suitable for filling vertical joints up to 5 cm wide. Cavities or 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 thickness and then apply a sealant joint on the bottom of joints of suitable section to obtain airtightness and watertightness. All building elements should be temporarily fixed until the foam is fully cured. The final strength is obtained after complete polymerization. Can be painted after 24 hours of drying at + 20 ° C: preliminary test.
