Key Features and Specifications of Dirko HT Beige

• Chemical Basis and Curing:

  • Oxime-Silicone: Dirko HT Beige is based on oxime-silicone, which ensures a neutral curing process at room temperature. This prevents the formation of acidic by-products, making the product safe for use on sensitive metal surfaces without the risk of corrosion.
  • Single-Component: The sealant is ready to use and requires no mixing or activation. This makes the product easy to apply without additional tools or preparation.
  • Room Temperature Vulcanized (RTV): Dirko HT Beige cures at room temperature through a reaction with moisture in the air, resulting in a durable, elastic seal that withstands high temperatures and harsh conditions.

• Temperature Resistance:

  • Wide Temperature Range: Dirko HT Beige can be used at temperatures ranging from -50°C to +250°C and can withstand short-term peaks up to +315°C. This makes the product ideal for applications with high thermal stress, such as engines, exhaust systems, and other extreme heat environments.
  • Sustained Elasticity: The sealant retains its elasticity and adhesion even with prolonged exposure to extreme temperatures, which is crucial for maintaining reliable seals in demanding environments.

• Chemical Resistance:

  • Resistant to Various Chemicals: Dirko HT Beige offers high resistance to a wide range of chemicals, including mineral oils, synthetic oils, greases, coolants, UV radiation, salt water, and cleaning agents. This chemical resistance makes the product particularly suitable for use in engines, transmissions, and other systems exposed to aggressive substances.

• Physical Properties:

  • Shore A Hardness: 40 ± 5 according to DIN 53505, providing a firm yet flexible seal for various applications.
  • Density: 1.18 ± 0.2 g/ml according to DIN 53479, ensuring a strong yet elastic seal.
  • Elastic Modulus: 1.0 ± 0.2 N/mm² according to DIN EN ISO 8339, meaning the sealant can absorb stress without cracking, even under high pressure.
  • Elongation at Break: 400 ± 100% according to DIN 53504, demonstrating that Dirko HT Beige can accommodate significant deformation without failure.
  • Tensile Strength: 3.3 ± 0.2 N/mm² according to DIN 53504, indicating strong adhesion and durability.

• Media Resistance:

  • Durable Under Stress: Tests show that Dirko HT Beige maintains its physical properties even after prolonged exposure to high temperatures and aggressive media such as engine oil and water-glycol mixtures. This makes the product particularly suitable for applications requiring constant exposure to challenging conditions.

• Applications:

  • Automotive Applications: Dirko HT Beige is ideal for sealing valve covers, oil pans, water and oil pumps, differentials, gearboxes, oil sumps, thermostat housings, and control housings. It is also suitable for sealing headlights, taillights, and battery housings where waterproofing and chemical resistance are essential.
  • Industrial Applications: Dirko HT Beige can be used in a wide range of industrial applications, such as sealing flange connections and other systems exposed to high temperatures and aggressive chemicals.

• Processing and Use:

  • Application Temperature: The sealant can be applied at ambient temperatures between +5°C and +35°C. For optimal adhesion, the surfaces to be sealed should be clean, dry, and free from oil and grease.
  • Drying Time and Curing: Dirko HT Beige forms a skin within 5 to 10 minutes at 23°C and 50% relative humidity. Full curing occurs within about 24 hours under the same environmental conditions, with a curing rate of approximately 4.5 mm per day.
  • Application Instructions: The product should be applied evenly to the surface to be sealed. Parts can be assembled immediately after application or once the sealant has formed a skin, depending on the specific requirements of the application.

• Storage and Shelf Life:

  • Optimal Storage Conditions: Dirko HT Beige should be stored in a cool, dry environment at temperatures between +5°C and +25°C. In unopened packaging, the product has a shelf life of at least 12 months.
  • Usage After Opening: After opening, the tube should be tightly sealed to prevent premature curing. The product should be used as soon as possible after opening for best results.

• Packaging Options and Product Codes:

  • 70ml Tube (Product Code: 030.793): This compact packaging is ideal for smaller repairs and applications. The tube comes with a tube key and nozzle for precise application.
  • 200ml Compressed Gas Cartridge (Product Code: 036.166): This packaging is suitable for applications requiring a larger amount of product. The gas cartridge allows for easy and even application, especially on larger surfaces.
  • 310ml Cartridge (Product Code: 036.163): For industrial applications requiring a lot of material, this larger cartridge offers the ideal solution. This packaging is designed for use with a cartridge gun and is perfect for professionals who regularly perform sealing work.
