DWH 311 P is a high-viscosity two component adjustment and adhesive coating on epoxy-resin basis with aluminium fillers, designed for form- and forcefitting filling and gluing of joints on components, assemblies of different maerials. Due to spatula- and molding techniques it is possible to even achieve precision in µm-range. When using a micro-thin layer of Diamant-parting agent on the counter surface DWH 311 P can be seperated from it. The result is an exact copy of the molded surface. A high-perision preperation of surfaces and the mechanical post-processing of the surfaces is not necessary. In modern production processing times and costs can be dramatically reduced.
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

Extreme dimensional stability after curing
Excellent load transfer due to complete contact of the surfaces
Temperature resistance upto +80 °C
Excellent damping properties thanks to the E-module ca. 8600 N/mm²
Aluminium-grey color after curing
High resistance to oils, cooling emulsions, mineral and synthetic coolants and lubricates and many other chemicals.
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. Protect 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.
To mix DWH 311 P, 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. The deaeration described below also results in a final mixing.
Remove DWH 311 P from the container immediately after mixing and spread thinly, crosswise, on a clean sheet. By spreading, a further mixing effect is achieved, but in particular stirred-in air bubbles are broken up. furthermore, a part of the reaction heat is dissipated by the flat spreading, whereby the processing time is secured.
Description of use
First apply DWH 311 P with a trowel as a thin adhesive layer firmly onto the adhesive primer.Further trowel the product on the roof with a small excess without trapping air.The excess quantity applied should displace the air when moulding the components and thus ensure bubble-free application.
