5) Storage

    Correctly stored in its original closed container at room temperature (max 30). SQUARE® LIM2930/2945AB has a shelf life of 12 months. The ready to use LIM2930/2945AB should be kept tightly closed, if doesnt , it will affect the shelf life.

6) How to use

    Ready-to-use mixturescomponents  A and Bare fed directly to injection molding machine from the original containers by means of a metering end mixing unit called static mixer The mixtureat the mixing ratio 11 is injected into the heated mould. The shelf life is 7 days (23°C) after mixing. The pipline should be cleared if the machine wont work for long time.

7) Packaging

    SQUARE®LIM2930A/B and LIM2945A/B are available in 20kgs pails or 200kgs drums.
