F-874 Muraculon will produce a skin/membrane on unskinned polyurethane foam to create a barrier to moisture and chemicals. This skin has excellent resistance to fluids and petroleums. F-874 is a tough coating that adds durability to foam and imparts abrasion as well as puncture resistance.
These qualities find particular use in the medical industry, where cushioning and positioning devices are fabricated and used in sterile environments, as well as therapeutic practices. Other uses include cushioning for athletic devices, seat cushions, packaging and acoustical panels. F-874 is an excellent, cost effective replacement for Hypalon® coating.

To accelerate final drying, place coated object in ventilated oven at 100ºF-140ºF for 5 minutes. Make sure heat source is safe for this use and that you ventilate properly. To increase coating speed, you may increase atomizing pressure; open material adjustment and pattern adjustment to your comfort level. |
