## Features

- 🚗 Automotive-Grade RTV Silicone: Our RTV silicone is designed specifically for automotive engines, effectively sealing to prevent oil and gas leaks. It’s also ideal for gearboxes, axles, and pump superchargers, forming a reliable silicone gasket.
- 🔥 Durable & Flexible Gasket Sealant: Curing quickly, this sealant forms a leak-proof, flexible gasket that withstands high temperatures, pressure, and vibration without shrinking or cracking, ensuring a lasting and strong bond.
- 💧 High-Temperature & Oil-Resistant: Resistant to oil, corrosion, water, and extreme temperatures, our silicone sealant fully fills gaps, seals completely, prevents fluid leaks, and reduces energy loss, even in the toughest conditions.
- 🛠️ Application Tips: Clean the surface oil with a cleaning fluid, then apply the high-temp silicone evenly. During curing, apply pressure to ensure complete gap filling for optimal performance and durability.
- ⚠️ Important Notes: Perform a sealing test after application to prevent instrument damage. Curing time varies by environment (e.g., at 25℃, 10-30 min); temperature range: -60 to +300°C; ultimate pressure: ≥10MPa.
