Sikaflex 521UV UV Resistant LM Polyurethane Sealant - 10.3oz(300ml) Cartridge - White
Sikaflex-521 UV is a multi-purpose, UV resistant, non-sag, elastic, one-part silane-terminated polymer sealant, which cures on exposure to atmospheric moisture to form a durable elastomer. Sikaflex-521 UV is solvent and isocyanate free.
Sikaflex-521 UV bonds well to a wide variety of substrates without the need for special pre-treatment and is suitable for making permanent, high strength elastic seals. Compatible substrate materials include wood, metals, (particularly aluminum including anodized components), sheet steels (including phosphated, chromated and zinc-plated components), metal primers and paint coatings (two-part systems), ceramic materials, plastics and glass.
