Vinyl Ester Resins RIPOXYTM R-800 Series RIPOXY R-802

RIPOXY R-806

1.

lntroduction REPOXY R-802 ard R-806 are vinyl ester resins that offer unique performanc€ and a wide range of versatility. They havJouttanding corosion rcsistance to a variety of acids and especially to alkalies.

They also have outstanding mechanical properties such as resiliency and elongation, whi;h can't be obtained with other types ofresin, especially suitable for large-sized {llament winding prooess. Low viscosity and rapid curing make RIPOXY R-802 and R-806 suitable to general hand lay-up molding and other applications.
