Ceramic Glass Hermetic Sealant for Heaters

Ceramic Glass Hermetic Sealant for Heaters

The Ceramic Glass Hermetic Sealant is a low-temperature sealing material specifically designed for the manufacture of tubular heaters and other heating elements. This innovative product is applied to the terminals of heaters, where the glass beads melt rapidly under flame heating or high-frequency conditions to create a hermetic and durable seal. Its special formulation allows for excellent adhesion to metallic materials, providing electrical insulation and a hermetic seal between the outer metal and the inner metal tube. This material is a superior alternative to traditional sealing methods, meeting environmental standards and positioning itself as a leading option in the global market for high-quality sealing products.

1400°C High-Temperature Inorganic Sealant for Heaters

1400°C High-Temperature Inorganic Sealant for Heaters

The Thermo-Resistant Inorganic Adhesive 3732 is an innovative, high-performance solution designed for applications demanding extreme thermal stability and robust bonding in high-temperature environments exceeding 400°C. Unlike traditional inorganic adhesives based on silicates or phosphates, which present limitations in water resistance, dielectric insulation, and ease of use, the 3732 is formulated with metal alkoxides as a binder. This waterproof heat sealant is a single-component product that cures at low temperatures and generates minimal foam, greatly simplifying its application and handling. Once cured, the resulting material is 100% inorganic, offering exceptional resistance to oxidation, excellent dielectric rigidity, and superior sealing capability—significantly expanding its range of applications compared to conventional alternatives. It is ideal as a sealant for heating elements and for the protection of cartridge heaters, tubular heaters, immersion heaters, etc., guaranteeing durability and safety.

Silicone Oil for Electric Heaters

Silicone Oil for Electric Heaters

Our moisture-proof silicone oil, also known as hydroxyl-terminated polydimethylsiloxane (PDMS), is a high-purity, high-performance silicone polymer designed specifically for industrial applications demanding exceptional high-temperature resistance and superior electrical insulation. This silicone fluid, appearing transparent and colorless, is characterized by the presence of reactive hydroxyl (-OH) groups at the ends of its polydimethylsiloxane chain. This unique functionality allows the oil to act as a chain extender and structural control agent in the formulation of silicone rubber (RTV), sealants, and adhesives. By reacting with curing agents and cross-linkers, it forms a stable and durable polymeric matrix, offering robust protection and reliable performance under the most demanding conditions. Its versatility makes it an indispensable component for manufacturing products that require excellent moisture-proof protection and thermal stability.
