Elring Dirko HT Black 70ml Liquid Gasket - High Temperature Resistance

Elring Dirko HT Black is a high-quality, heat-resistant sealant specially designed for demanding industrial and automotive applications. This single-component, oxime-based silicone sealant offers enduring elasticity and excellent adhesion to a wide range of materials, including standard metals, cast iron, various plastics (except PE, PP, and PTFE), and glass. Its neutral curing process, which does not release acidic by-products, results in a durable and flexible silicone seal resistant to extreme temperatures and various chemical influences.

Key Features of Dirko HT Black

• Chemical Base and Curing: Dirko HT Black is based on oxime silicones, ensuring a neutral curing process at room temperature. This makes the product safe for use on sensitive metal surfaces, as it does not cause corrosion. The sealant is designed to react quickly with humidity, resulting in a firm, elastic seal that withstands heavy mechanical and thermal loads.

• Excellent Temperature Resistance: Dirko HT Black can be effectively used at temperatures ranging from -60°C to +285°C and can withstand short-term peaks up to +315°C. This impressive temperature resistance makes the sealant ideal for applications in environments with high thermal stress, such as engines, exhaust systems, and heating installations.

• Superior Adhesion: Dirko HT Black offers excellent adhesion to various materials, including galvanized steel, aluminum, and certain plastics like polyamide 6.6. The sealant provides reliable seals without the need for a primer, ensuring easy application and long-lasting performance, even under the most challenging conditions.

• Long-Lasting Elasticity and Durability: With a break elongation of 400% and a tensile strength of 3.3 N/mm², Dirko HT Black offers both flexibility and durability. After curing, the sealant remains elastic, making it resistant to vibrations and mechanical stresses without cracking or breaking. This makes it particularly suitable for applications where movement and flexibility are required.

• Chemical Resistance: Dirko HT Black is resistant to a wide range of chemicals, including mineral oils, synthetic oils, lubricants, coolants, UV radiation, saltwater, and both cold and hot water. This extensive chemical resistance ensures that the seal maintains its integrity even in aggressive environments such as engine compartments and industrial installations.

Applications Elring Dirko HT Black is suitable for a wide range of applications where durability and heat resistance are crucial:

• Valve Covers and Oil Pans: Dirko HT Black is ideal for sealing valve covers and oil pans in engines, where the sealant must withstand high temperatures and oils. It provides a reliable seal that prevents fluid leaks and protects engine components from contamination.

• Water and Oil Pumps: The chemical resistance of Dirko HT Black makes it a perfect choice for sealing water and oil pumps, where the product must withstand constant exposure to coolants and lubricants.

• Thermostat and Control Housings: This sealant provides reliable seals in thermostat and control housings, essential for preventing leaks and maintaining system efficiency.

• Gearboxes and Drives: From differentials to transmissions, Dirko HT Black provides reliable seals that resist both mechanical and thermal stresses, contributing to the long life and performance of these components.

• Flange Connections and Lighting Elements: The sealant is also suitable for sealing flange connections and lighting elements, where waterproofing and durability are essential.

Application and Use Using Dirko HT Black is straightforward and requires no special equipment or skills. For best results, ensure that the surfaces to be sealed are clean, dry, and free of oil and grease before applying the sealant. The sealant can be applied at ambient temperatures between +5°C and +35°C. After application, the sealant quickly forms a skin and cures fully within 24 hours under normal environmental conditions.

Storage and Shelf Life Dirko HT Black should be stored in a cool, dry environment (+5°C to +25°C) to maintain product quality. In an unopened package, the product has a shelf life of at least 12 months, allowing it to be stored safely for future use.

Conclusion Elring Dirko HT Black is a versatile and reliable sealant specifically designed for applications in both automotive and industrial sectors. With its excellent temperature and chemical resistance, strong adhesion, and lasting elasticity, this sealant provides the performance and durability needed to ensure reliable seals even in the most demanding conditions. Whether for engines, pumps, or other industrial equipment, Dirko HT Black offers a robust solution for all your sealing needs.
