The silicone cures on exposure to moisture in the air, forming a flexible, water-resistant seal around soldered connections and cut ends without requiring heat or pressure.\u003c\/p\u003e\n\u003cp\u003eUsed in outdoor LED installations, architectural lighting runs and IP-rated retrofit projects where strip-to-strip joints or strip-to-cable connections need protection from water ingress. The silicone is applied directly to the connection point, then covered with heat-shrink tubing to create a double-layer seal. Once cured (typically 24 hours at room temperature), the silicone remains flexible and resistant to UV degradation, vibration and thermal cycling between -40°C and +200°C.\u003c\/p\u003e\n\u003cp\u003eThe 20g tube includes a precision nozzle tip for controlled application without excess waste. One tube seals approximately 10-15 standard LED strip joints depending on the width of the strip and the length of the connection. The silicone is non-corrosive to copper PCB tracks and solder points, and can be removed mechanically if a joint needs to be redone.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e100 x 20 x 20mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e22g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eHow long does the silicone take to cure?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eRTV silicone cures on exposure to moisture in the air. Surface cure (when the outer layer is no longer tacky) typically occurs within 30-60 minutes at room temperature and 50% humidity. Full through-cure to maximum strength takes approximately 24 hours. Higher humidity accelerates curing; very dry environments slow it down.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan it be used on 12V and 24V LED strips?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. The silicone is electrically insulating and non-conductive once cured, making it safe for low-voltage DC LED strip connections at 12V, 24V or 48V. It does not interfere with the electrical function of the joint.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I still need heat-shrink tubing?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eHeat-shrink tubing is recommended as a secondary layer over the silicone. The silicone provides the waterproof seal; the heat-shrink provides mechanical protection and strain relief for the connection. Together they form a more durable and weather-resistant joint than either material alone.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow many joints does one tube seal?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA 20g tube typically seals 10-15 standard LED strip joints (8-10mm wide strips with typical solder connections). Wider strips or longer cable runs may use more silicone per joint. Apply a thin, continuous bead around the connection rather than a thick glob — excess silicone does not improve sealing and takes longer to cure.\u003c\/p\u003e","brand":"AVSL","offers":[{"title":"Default Title","offer_id":45313166835979,"sku":"153.627UK","price":2.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/153627UK_CO1_38020fce-d5bf-43e4-9fe8-a74906fcdebc.jpg?v=1715188609","url":"https:\/\/niori.co.uk\/products\/lyyt-705-rtv-silicone-glue-for-led-strip-waterproofing","provider":"Niori","version":"1.0","type":"link"}
