F-874 Muraculon is a unique vinyl based coating that when spray applied provides a durable, flexible protective coating on polyurethane foams. F-874 can also be used on molded polyurethane and closed cell foam containing vinyl.
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.
