📝 Description
The TOSSEAL™ 381 Neutral Silicone is a high-performance, one-part sealant developed in Japan for glass-to-glass and glass-to-metal applications. Unlike acetic silicones, it cures with a neutral ketoxime system, making it non-corrosive, low-odor, and safe for metals.
This silicone is highly durable, weather-resistant, and compliant with JIS A 5758 G-30SLM, ensuring long-lasting adhesion in both residential and commercial projects.
✔️ Neutral cure – won’t corrode metals, low odor
✔️ Strong adhesion – glass, aluminum, steel, concrete
✔️ Weather & UV resistant – long-term durability
✔️ Fast tack-free time – ~10 minutes at 23 °C
✔️ Professional grade – widely used in construction and refrigeration
