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.

of

unsaturated Polyesters.
