Product Overview
Rainbow RAL Coloured Silicone Sealant is a professional‑grade, neutral‑cure silicone engineered for high‑performance sealing across glazing, sanitary, construction and façade applications. Each cartridge is colour‑matched to the official RAL colour system, ensuring seamless, visually perfect joints. With 60+ stocked RAL colours, Rainbow provides precise matches for window frames, cladding, composite panels, furniture finishes and interior detailing.
Formulated with fungicide protection, Rainbow Silicone is ideal for kitchens, bathrooms and high‑humidity environments where mould resistance is essential. It is MEKO‑free, low‑odour, and fully compliant with EU safety standards — delivering a safer, cleaner working experience without compromising performance.
Rainbow Silicone adheres strongly to metal, plastic, brick, timber, glass and coated surfaces, making it suitable for both interior and exterior use. Once cured, it forms a durable, flexible joint that resists UV, weathering and long‑term ageing.
