Applications:

  • Coating for all screws, vacuum sealing of threaded joints, for air supply pipes,…;
  • Specialized for sealing bolts, screws, threaded protection;
  • When determining the tightening torque considering the frictional torque of the screws, the following total frictional torques can be used for the calculation: μ total 0.10 to 0.13 on blank stainless steel screws, μ total 0.13 to 0.17 on phosphated stainless steel screws;
  • Low strength for easy to remove adhesive;
  • Range of temperature to use: 600C ~ 1800C, (Depended to the certain application may be other limited);
  • The surface to bond must be clean, no dust, grease as well as other contaminations, use DELOTHEN cleaner to best bonding.

Curing:

  • Anaerobic curing at room temperature, under metal surface catalyst, initial curing after several minutes and finally cured within 24h;
  • The curing may be assisted by heat addition or activator as DELO-QUICK,…

Technical data:

  • Color: blue, prefer clearance: 0.05 ~ 0.1 transperant up to 0.4 mm if heat addition or be activated;
  • The gap distance when applying heat or condensative activator: up to 0.3~0.4 mm;
  • Density: 1.1 g/cm3;
  • Viscosity: 1000 mPas, thixotropic;
  • Curing time until initial strength, at 23oC, anaerobic:

+) on zinc phosphated screw: 5~20 min;

+) on V2A steel screw: 5 min;

  • Curing time until final strength: 24h;
  • Off-toque:       +) without M(on): 18 Nm;

+) with M (on) =46 Nm: 50 Nm;

  • Compression shear strength: 15 MPa;
  • Compression shear strength after 1 hour cured: ~2 MPa;
  • Chemical resistant: very good;
  • Storage life: 12 months, at room temperature (max. 25oC), with unopened original cardtrige up to 600 ml.
