       Low yellowing

       Outstanding resistance to ageing

       Meeting US FDA CFR21. Part .177.2600,EN14350.2 and EU RoHS

            standard

4) Application

     SQUARE@Lim19XXA/B is suitable for making kitchenwares.

5) Storage:Correctly stored in its original closed container at room temperature (max 27°C). SQUARE^@Lim19××A/B has a shelf life of 180 days. The ready to use LIM19××A/B should be kept tightly closed and used up within 7 days.

6) How to use:Ready-to-use mixtures(component A and B) are fed directly to injection molding machine from the original containers by means of a metering end mixing unit (called static mixer. The mixture(at the mixing ratio 1:1) is injected into the heated mould at the mould temperature of 140-160°C,the mixed silicone rubber will be vulcanized in a few seconds. 

7) Packaging

   SQUARE@Lim19XXA/B is available in 20kgs pails or 200kgs drums.
