WEICON Black-Seal

High temperature engine sealant

WEICON Black-Seal is a black, high-temperature (up to +300°C) adhesive and sealant. Solvent-free, durable, resistant to oils, greases and pressure, aging and highly elastic (breaking elongation 500%). Black-Seal is designed for gluing and sealing in applications requiring high resistance to oils and greases. WEICON Black-Seal can be used on gearboxes, valve covers, transmissions, oil sumps, tanks, flanges and much more.

Application:

  • in gearboxes
  • in the valve covers
  • in gears
  • in oil pans
  • in tanks
  • in collars

Features and Benefits:

  • high temperature
  • durable
  • resistant to oils
  • resistant to lubricants and pressure, aging
  • has high flexibility

Application method:

The surfaces must be clean and grease-free. Many surface contaminants such as oil, grease, dust and dirt can be removed with WEICON Surface Cleaner. We recommend WEICON Spray Cleaner S for dirty metal surfaces; WEICON Sealant and Adhesive Remover is suitable for removing old paint or adhesive residue. Most materials can be easily combined with each other and with each other. We recommend the use of a primer (WEICON Primer) for certain materials or extreme requirements. Mechanical surface treatment (e.g. by grinding or sandblasting) can significantly improve the adhesion of the adhesive.

Methods of use:

Cartridge Gun method of use

Adhesive application gun (310 ml cartridge), compressed air gun, we recommend the version with a plunger (WEICON Pneumatic dispensing gun), automatic dosing systems. Tube processing Squeeze by hand, close immediately after use, once opened should be used as soon as possible.

Method of application pressure pack

Remove the closure. Regulate flow rate Max. or Min. Press handle and distribute medium. After turning the valve to the "min." the valve closes automatically and the product flow is stopped. Connecting glued parts
