Sikaflex 521 White UV Sealant - 300 ml
Sikaflex-521 UV is a multi-purpose, UV-resistant, non-sag, elastic, one-part silane-terminated polymer sealant. It cures on exposure to atmospheric moisture to form a durable elastomer. It is solvent and isocyanate free. It 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 on timber, metals (including aluminium and anodised components), sheet steels, metal primers and paint coatings, ceramic materials, plastics, and glass.
The product is age and weathering resistant, low odour, non-corrosive, and offers high electrical resistance. It can be sanded and overpainted once cured.
