Using Clumped Propolymer and Proper Storage

Hello,

Regarding your Propolymer that has clumped, this is a common issue caused by moisture entering the container. The plastic jars typically used are not moisture-proof.

1. Can it still be used?

   • Generally, yes, if the clumps are not hard and clear. If the clumps are hard and clear, it's best to discard it. If the clumps are more like powder that has stuck together and can be broken apart, it is likely still usable.
   • Using clumped Propolymer will be more difficult as it takes longer to dissolve. You can try warming your formula slightly and stirring for a longer period.
   • A helpful tip is to "sift" the Propolymer before use by pressing it through a fine sieve. This breaks up the clumps into a finer powder, making it dissolve much faster and easier to incorporate evenly.

2. How should it be stored in the future?

   • To prevent clumping, proper storage is crucial to protect it from moisture.
   • Always store the Propolymer in its original foil bag.
   • Keep the desiccant packet (moisture absorber) with the Propolymer. It is recommended to place the desiccant packet inside the Propolymer container itself, close the lid tightly, and then place the container back into the foil bag. For extra protection, you can add another desiccant packet to the foil bag.
   • Seal the foil bag tightly (e.g., by folding and securing with a rubber band).

By following these storage tips, you can help prevent moisture from reaching the Propolymer and keep it in a usable powder form.
