One Component RTV Silicone Sealant (Translucent) - 9307TL

Kootai 9307TL is a room-temperature vulcanizing (RTV) silicone that offers a balance of flow performance and adhesion for a range of substrates including metal, glass, plastics, and gypsum board. It maintains stable elasticity across a wide temperature range (-40C to +180C) and demonstrates strong dielectric insulation (volume resistivity: 3.5 10 cm). The product cures within 24 hours under ambient conditions and provides reliable weatherproofing and waterproof sealing, making it ideal for sensitive electronic and electrical components. It complies with EU RoHS directives and is safe for general storage and transport.
