After 10 years of experience of Peramin® Conpac 500 and Peramin® Conpac 700 on the market, Peramin has extended the shelf life warranty of these products to 18 months instead of 12 months.
The robustness of the products have been confirmed in an aging study where they were exposed to different higher humidity and temperature.
The conclusions of the study are the following:
- The exposed powder absorbs some humidity in balance to the environment but it does not form lumps or agglomerations.
- Testing of the exposed powder in a reference self levelling formulation does not show any decline in performance of setting time, flow or flexural and compressive strength.
For optimal performance, Peramin® Conpac 500 and Peramin® Conpac 700 should be stored in its original packaging, in dry conditions at 5 – 40ºC and not in direct contact with the ground or double stacked.
When stored in these conditions, performance is guaranteed for a minimum of 18 months.
