ML-DB overview

Application:

  • DELO ML is very flexible, uniform pressure resistance, suitable for metal-glass, metal-plastic joints.
  • Applications of DELO ML include:
  • Fixation, tightening coaxial connections;
  • Screws on materials without drilling
  • Mounting pipes, bolts, metal joints
  • Glue for the industries of engine manufacturing, automobile assembly, consumer electronics assembly, mechanical engineering
  • High strength adhesive for coaxial, rack, or socket mounting.

Some typical applications of DELO-ML glue:

1. Thread locking, vacuum sealing of threaded joints, pipes

 Material parts:

  • Copper;
  • Brass;
  • Using  DELO ML 5849 glue, the cured adhesive can be easily removed when needed by heating. 

Test requirements:

  • Tightness test (water);
  • Use temperature range: max. 50 ° C warm water;
  • When the connectors are screwed tight, the glue is only intended to prevent loosening and seal;
  • The glue can be easily removed when you want to remove it.

2.  DELO ML glue is used in fixing bolts of reducer gears

  • Thread these bolts with DELO-ML 5327 glue. During operation, screws and adhesives are contacted to the hot oil at temperatures up to +90°C.

Material Composition:

  • Bolt: steel
  • Gear: cast iron

 

Vacuum seal for oil level checking screw: 

The oil level check screw bonded with DELO-ML 5149 low strength adhesive has a sealing function in this case. When required, it must be possible to remove the screw back.

3.  EBM-Papst Electric Car Engine Magnet Bonding

Material Composition:

  • Rotor: E235 tube steel, plated or passivated;
  • Magnet: NdFeB, passivated;
  • Use ML DB180 glue in combination with DELO QUICK-5006 activator.

The requirements and parameters of the glue test passed:

  • Prefer a 1-component adhesive.
  • Fix the magnet to the steel rotor (rotation speed up to 1,500 1/min).
  • Operating temperature range: -40 °C to +120 °C.
  • High yield with curing time < 10 s using DELOLUX 80 & 20 UV lamps.
  • Good adhesion between flat and smooth surfaces.

 Tests:

  • Thermal shock test: -40 °C to +85 °C, 500 cycles, 30 minutes each half cycle.
  • Tensile shear strength > 500 N at room temperature.

Dispensing method: 

  • The bonded surface needs to be clean from dust, grease, recommend DELOTHEN products to get the most perfect surface.
  • The adhesive can be easily applied by hand or used in conjunction with DELO's dedicated dispersant - DELOMAT 100, which is compatible with anaerobic curing adhesives.
  • The adhesive has a low viscosity, the visible margin of the glue can use light to cure. The adhesive has high strength, is difficult to remove, good adhesion even to surfaces with low roughness.

DELOMAT 100 dispenser

Curing process: 

  • In an anaerobic environment for several minutes.
  • The curing speed of the glue can be increased by heating or using an activator or by UV light with a wavelength from 320 ~ 450 nm for a gap as large as 4 mm.
  • Refer to the standard wavelength range of the DELOLUX 20/50/80  LED lamps.
