Anaerobic Adhesives and Sealants

KRYLEX® high performance anaerobic adhesives all cure in the absence of air and the presence of active metal ions. The chemically harden to form a tough structural solid that prevents loosening and seals against leakage and corrosion. Our range of products comes in a variety of viscosities, strengths, and cure speeds to meet all applications requirements.

  • Threadlockers – prevent vibration and loosening and seal against leakage and corrosion. One bottle of KRYLEX® threadlocker takes the place of a wide variety of traditional vibration proofing methods, reducing cost and increasing performance.
  • Thread Sealing – designed for thread and pipe sealing, replacing traditional PTFE tapes and dopes. Products instantly seal and will not shred, evaporate or shrink. KRYLEX® sealants resist pressure, vibration and temperature cycling as well as hydraulic fluids, oil, fuel and
  • Gasket Makers – create formed in place gaskets on flanges and housings, eliminating the need for large inventories of pre-cut gaskets. Once cured, KRYLEX® gasket makers key into the adjacent faces of the joint and will not relax or shrink and have exceptional pressure and
    solvent resistance.
  • Retaining Compounds – used in the assembly of all coaxial components such as bearings, gears, shafts, bushes, pulleys, cylinder liners and rotors. They increase the load bearing characteristics of cylindrical joints, reducing assembly stresses and assembly costs.
