RTV Silicone Sealant 9307TL 300ml

Product Description

9307TL is a translucent, one-component RTV silicone sealant with excellent insulation, weather resistance, and wide-temperature performance, designed for electrical and LED sealing applications.

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 (-40°C to +180°C) and demonstrates strong dielectric insulation (volume resistivity: 3.5 × 10¹⁴ Ω·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.

FAQs

Q1: How long does 9307TL take to cure?

A: Surface drying occurs within 3–6 minutes; full cure is typically achieved within 24 hours at 25°C with 55% humidity. Thicker applications (>6mm) may require up to 7 days.

Q2: Is 9307TL electrically insulating?

A: Yes, it offers high insulation with volume resistivity rated at 3.5 × 10¹⁴ Ω·cm.

Q3: Can it be used on plastic or marble surfaces?

A: Absolutely. It adheres well to plastics, marble, glass, and metals without corroding them.

Q4: Is it safe to use around children or in enclosed spaces?

A: Once cured, it’s non-toxic. Before curing, avoid contact with skin and eyes, and ensure good ventilation.

Q5: How should it be stored?

A: Store in a dry, cool place away from sun or rain. Shelf life is 5 months at 25°C in sealed packaging.
