Bondloc B638 Retainer

Bondloc B638 is a high strength retaining compound designed for the bonding of cylindrical fitting parts, with bond gaps approaching 0.2mm.

The product cures when confined in the absence of air between close-fitting metal surfaces and prevents loosening and leakage due to shock and vibration. It also has good oil tolerance to minor surface contaminants.

Ideal for shafts, gears, pulleys and similar cylindrical parts.

Quick tips Dr Stuk
  • Cures with the absence of air and contact with metal or copper ions
  • Excess deposits will not cure and can be easily wiped away
  • Clean surfaces prior to use with B7063 Cleaner for improved performance
  • Not suitable for use on Plastics or Oxygen rich systems
  • The bottle is only half full, as air space maintains product stability
  • Apply localised heat to remove high strength grades
  • Colour of the product helps denote the product strength - Red and Green are high strength
  • To increase cure speed on passive and inert materials use B7649 Activator
