A: Jingu holds 20 years of chemical formulation expertise, an ISO9001/ISO14001 certified 10,000㎡ factory, a dedicated 30+ R&D team, and a stable annual capacity of 256 tons, ensuring zero-defect quality and consistent supply for clients in 150+ countries.

Jingu's high-performance rtv silicone sealant is engineered with a 100% silicone formulation designed for one-component neutral room-temperature curing. Specially formulated for harsh working environments, it offers low odor, non-corrosive, non-sagging, and easy-application benefits (no pre-mixing required).
Physically and chemically, Jingu rtv silicone sealant exhibits excellent thixotropy and high elasticity. Once cured, it withstands operating temperatures from -60°C to +320°C and internal pressures up to 12MPa. Its outstanding resistance to engine oil, gear oil, coolant, and vibration effectively prevents leakage caused by thermal expansion, contraction, or intense movement on mechanical mating surfaces.
