Storing and handling polyacrylamide granules
Keep Sunfloc in condition for its full 24-month shelf life, and handle it safely on site.
Storage
Keep bags sealed, dry and out of direct sunlight, at 0–35 °C. Moisture makes granules cake.
Shelf life
24 months in the original unopened pack for all four Sunfloc grades.
Spills
Wet polyacrylamide is very slippery. Sweep up dry spills, avoid raising dust, and wash the area afterwards.
Protection
Wear gloves and safety goggles, and a dust mask in dusty conditions. Keep away from strong oxidising agents.
Made-up solution
Use within a day. The HQ specification sheets list solution stability in DI water as 1 day.
Documents
The SDS for each grade covers first aid, fire-fighting and disposal. Download it from the grade page.

Read →What the safety data sheets agree on
Supplier safety data sheets for polyacrylamide products agree on a few points. The powder or granule is hygroscopic and should be kept dry with the container closed. Wet product makes floors extremely slippery, and the usual advice is to keep people away from a spill, sweep up dry material, and treat wet areas with care. Fine organic powders can also form dust clouds, so avoid dust and ignition sources.
In practice: store bags off the floor on pallets, away from damp walls and from oxidising chemicals; reseal an opened bag with a clip or tie; and put a squeegee and absorbent grit near the make-up area. Make-up solution should be used within a day, because it loses strength as it ages.
Always read the safety data sheet for the exact grade you hold. Ours are on the Quality and Documents page.
