DWH 311 FL LowEx is a low-viscosity 2-component fine adjustment and adhesive coating based on epoxy resin with aluminium fillers. This is used for the form- and force-fitting filling and bonding of separating joints to components, assemblies and components of a wide variety of material components. By means of casting, injection and moulding, even complex shapes and structures can be created with a precision in the μm range.
DWH 311 FL can be detached by using a micro-thin layer of diamond release agent on the counter surface. The result is an exact copy of the molded surface. A high-precision preparation of surfaces and mechanical post-processing of the surfaces is not necessary. In modern production technology, process times and costs can be reduced many times over.

Typische Anwendungen

  • Form-fit and force-fit installation of guides in mechanical engineering.
  • Adjusting lining for assemblies and elements of various materials.
  • Full-surface relining of beams and elements as a substitute for lining plates.
  • Load-bearing gap compensation on beams of portal milling and gantry systems.
  • μm-precise fitting of bushings, centering and guiding elements.
  • Fixing and / or centering of bearing bushings after high-precision alignment.
  • As filler and composite material in 3D printing + additive manufacturing


  • Very high accuracy, μm-accurate impression
  • Very high compressive strength
  • Extremely dimensionally stable after curing
  • Excellent load transfer due to complete contact of the contact surfaces
  • Temperature resistant up to +80 °C
  • Excellent damping properties due to modulus of elasticity approx. 8700 N/mm²
  • Steel gray color after curing
  • High resistance to oils, cooling emulsions, mineral and synthetic coolants and lubricants as well as many other chemicals.
  • Very low reaction or curing temperature (< 40 °C in 100g batch).

Storage / Shelf life

Store in original, unopened container in a dry, cool and frost-free place (+5°C to +20°C). Shelf life 2 years. Keep away from direct sunlight. Higher temperatures reduce the shelf life.

Preparation of the bonding surface

The surfaces to be coated should have a significant roughening to improve adhesion. The peak-to-valley height should be 0.5 mm (Rt = 500μm). The roughening can be produced, for example, with a cutter head with a large feed on a milling machine.surfaces must be clean, dry and free of grease and oil. For cleaning dirty surfaces we recommend DIAMANT Cleaner #1417 or DIAMANT Cleaning Spray #1534.Surfaces to which DWH should not adhere should be coated with Release Agent #1354 or Release Spray #1355.

Mixing Procedure

To mix DWH 310 FL, add Component B completely to the Component A container. Mix intensively with a drill and the DIAMANT mixing propeller (Prod. No. #0789) (max. 250 rpm for approx. 2 minutes). Scrape off any material adhering to the wall of the container with a spatula and add to the mixture. Mix again thoroughly.


DWH 310 FL should be transferred in a long, thin uninterrupted stream into a clean vessel

Application description

DWH 310 FL can be poured free-flowing into the gap open at the top and of sufficient size.Alternatively, DWH 310 FL, after being transferred into a hand-held cartridge, can be injected through an inlet port into the prepared, sealed cavity. To avoid air pockets, the cavity is filled from the lowest point.
