Storage / Shelf life
Store in the original, unopened container in a dry, cool and frost-free place (5°C to 20°C). Shelf life 24 months. Protect from direct sunlight. Higher temperatures reduce the shelf life.
Processing parameters
The working time (pot life) of the material begins as soon as the two components A and B are added together. Pot life and hardening time depend on the amount of material and the temperature. With larger containers, the pot life may be reduced due to a higher reaction heat. The following table shows practical pot life values for a 1 kg pack:
Material curing can be accelerated by heating. The maximum permissible temperature for accelerated curing is 50 °C. The required, theoretical minimum curing temperature is +5°C. We recommend preheating the components and the material at temperatures <10°C.
Compressive swelling strength
Extensive fatigue tests (M1999 ibac RWTH Aachen) were carried out on MM1018 FL to determine the behavior of the material under alternating loads. Below you will find a brief excerpt of the data obtained. Further information is available on request.
Work preparation
If possible, contact surfaces that are wetted with MM1018 must be cleaned of dirt and loose particles using de-oiled compressed air. Screws must be protected if necessary (e.g. with DIAMANT screw protection #8880) to prevent the threads from sticking to MM1018 at a later date. If the contact surfaces need to be separated again at a later date, it is necessary to apply a release agent (e.g. DIAMANT Release Agent #1354) in advance.
Mixing process
To mix MM1018, component B is poured completely into the container with component A. Mix intensively with a hand drill and the DIAMANT mixing propeller (Art. No. #0789) (max. 250 rpm for approx. 2 minutes). Remove any material adhering to the walls of the container with a spatula and add to the mixture. Mix thoroughly again.
Application description
MM1018 liquid can be applied by pouring or injecting. In both cases it is necessary that the gap is sealed all around to prevent MM1018 from leaking out of the gap. The use of MM1018 SEAL #2108 is recommended for gap sealing. Information on material and processing can be found in the technical data sheet MM1018 SEAL #2108.
Pouring
The mixed MM1018 can be used for gap sealing by pouring it into a cavity. Before pouring, the mixed MM1018 must be transferred to a clean container. The material can be poured directly into the cavity from this container. Ensure sufficient ventilation and bubble-free pouring.
Injecting
MM1018 can be injected into a sealed cavity. A prerequisite for the injection are appropriate injection and ventilation openings, which must be planned depending on the existing gap dimensions or cavity. Injection is carried out via flexible plastic hoses (Prod. No. #1579) using shut-off valves (Prod. No. #1577) which are attached to the inlet and outlet points via R1/4″ screw connections (Prod. No. #1578). An approx. 150 mm long plastic hose, a shut-off valve and a further piece of hose designed to suit the working conditions for connecting the injection cartridge or for venting must be attached via suitable hose points (Prod. No. #1576).
MM1018 is mixed according to the processing instructions. The mixed product is then poured into an empty cartridge (Prod. No. #1573 – 320 ml) in as thin a stream as possible, avoiding the formation of air bubbles. After filling, the cartridge is closed with a cartridge piston and slowly rotated to allow the liquid MM1018 to flow from the tip to the piston. This causes the trapped air in the cartridge to rise to the tip of the cartridge. This process is particularly important for a bubble-free injection! The cartridge can now be opened at the top with a knife and the tip unscrewed. It is advisable to shorten the cartridge tip slightly so that it has an internal diameter of approx. 8 mm. This reduces the resistance during injection and makes it easier to press in. The cartridge tip is now placed on the free end of the hose by hand.
After opening the shut-off valve, injection can begin. Injection should be carried out at a constant pressure. It is essential to ensure that no air bubbles are pressed through the hose into the cavity! To change or refill the cartridge, the shut-off valve is closed to prevent the already injected material from flowing back. The free end of the hose is fixed for the cartridge change so that no material can leak out. Injection is stopped as soon as the material emerges from the upper vent opening. Close the shut-off valve before removing the cartridge. Any material flowing back out of the injection hose must be collected with a cloth, for example, and disposed of properly.
After 24 hours of curing at 20°C, the injection and vent connections can be cut off and disposed of.
Time schedule
