Description
MM1018 – The liquid backing plate – is a highly filled metal polymer for full-surface and non-positive compensation or filling of inaccuracies and bumps between metal elements such as head plates, bridge bearings, crane runways and rail guides and steel components. Due to its high dimensional stability, MM1018 is also suitable for use in prestressed connections. More than 1,000 structures worldwide are already based on the liquid lining plate, DIAMANT MM1018.
Pasty version for applying and inserting. Product cures at room conditions. Compressive strength of up to 133 N/mm².
MM1018 pasty is a product with general building authority approval (abZ). Approval number: Z-3.82-2042

Storage / Shelf Life
Store in the original, unopened container in a dry, cool and frost-free place (5°C-+20°C). Shelf life 24 months. Protect from direct sunlight. Higher temperatures reduce the shelf life.
Processing Parameter
The processing time (pot life) of the material begins as soon as the two components A and B are added together. Pot life and curing time depend on the amount of material and the temperature. With larger containers, the pot life can be reduced due to the higher heat of reaction. The table below gives practical pot life values for a 1kg package:
Material hardening can be accelerated by heating. The maximum allowable temperature for accelerated curing is 65°C. The required minimum curing temperature is +5°C. At lower temperatures it is recommended to preheat the components.
Work Preparation
Contact surfaces that are wetted with MM1018 must, if possible, be cleaned of dirt and loose particles using de-oiled compressed air. The diamond cleaner #1417 is recommended for this. The cleaner must be applied to a lint-free cloth, which is then used to clean the contact surface. Screws should be protected if necessary (e.g. with DIAMANT screw protection #8880) to prevent the threads from sticking to MM1018 later. If the contact surfaces have to be separated again at a later point in time, it is necessary to apply a release agent (eg DIAMANT release agent #1354) in advance.
Mixing Process
To mix MM1018, add component B completely to the container containing component A. Mix intensively with a hand drill and the DIAMANT mixing propeller (item no. #0789) (max. 250 rpm for approx. 2 minutes). Scrape off any material sticking to the wall of the container with a spatula and add to the mixture. Mix thoroughly again.
Application Description
MM1018 pasty is applied to the contact surface in an X-shape. The following illustrations show a square and a rectangular contact surface as an example. It is important to note that the highest amount of material is applied in the center of the contact area (see red line in the figure) so that MM1018 is spread as a paste when the contact areas are joined, without air bubbles and over the entire surface. After joining the contact surfaces, MM1018 has spread over the entire surface in a paste-like manner, free of air bubbles. Excess material that has been squeezed out on the sides of the contact surfaces should be removed before curing if possible.
