Better Control of Set Times for Fiberglass Mats


I need to find out if there is any way to store a coated fibre glass mat for a long time without it being set, and how can I reduce the setting time when the mat is taken out of the packing.

Please help

Thank you

When it comes to slowing chemical reactions temperature is usually the best bet. You can buy pre impregnated fibre glass cloths. These are stored for prolonged periods of time at -20C and as long as they are sealed air tight then they are perfectly OK when defrosted.

I would assume yours would behave similarly. They must be allowed to reach ambient temperature before being removed from the packaging. The water from any condensation will severely affect final strength after curing.
