Description

DWH 311 FL 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, complex shapes and structures can also be created with a precision in the μm range.
DWH 311 FL can be detached by using a micro-thin layer of Diamant release agent on the counter surface. The result is an exact copy of the molded surface. High-precision preparation of surfaces and mechanical post-processing of the surfaces are not required. In modern production technology, process times and costs can be reduced many times over.

Typical applicaions

Form- and force-fitting installation of guides in mechanical engineering,
Adjusting coating for assemblies and elements of various materials.
Full-surface lining of mouldings and elements as a replacement for feed plates.
Load-bearing gap compensation on beams of portal milling and Gantry systems
μm-accurate adjustment of bushes, centering and guide elements
Fixing and / or centering of bearing bushes according to high precision alignment
As filling and composite material in 3D printing + additive manufacturing

Characteristics

Very high accuracy, μm-accurate moulding
Very high compressive strenght
Extrem dimensional stability after curing
Excellent load transfer due to complete contact of the surfaces
Temperature resistance up to +80°C
Excellent damping properties thanks to the E-module ca. 8500 N/mm²
Aluminium grey color after curing
High resistance to oils, cooling emulsions, mineral and synthetic coolants and lubricates and many other chemicals.

Chemical resistance

Please contact our technicians for questions about chemical resistance.

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 311 FL, add Component B completely into 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.

Ventilating

DWH 311 FL should be transferred in a long, thin uninterrupted stream into a clean vessel

Application description

DWH 311 FL can be poured free-flowing into the gap open at the top and of sufficient size.Alternatively, DWH 311 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.
