CHEMICAL RESISTANCE GUIDE
Foreword
DERAKANE and DERAKANE MOMENTUM epoxy vinyl ester resins are designed and
manufactured by Ashland. These resins possess
outstanding corrosion-resistant properties and
satisfy critical requirements in Fiber-Reinforced
Plastic (FRP). Because they possess outstanding
corrosion-resistant properties DERAKANE and
DERAKANE MOMENTUM resins are particularly
well suited for tough industrial applications.
This guide briefly describes the various
DERAKANE and DERAKANE MOMENTUM
resins, and it presents detailed chemical
resistance data needed to assist engineers in
specifying and designing corrosion-resistant
FRP applications.
Recommendations given in this guide apply to
“state-of-the-art” corrosion-resistant structures.
Typically these structures have a corrosion barrier
that is 2.5 to 6.3 mm (100 to 250 mils) thick and
are designed for contact with a specific chemical
environment. The first layer of the corrosion
barrier usually is 0.3 to 0.8 mm (10 to 20 mils)
thick and is 95% resin, reinforced by one or two
surfacing veils. This layer is then backed with 2 to
6 mm (90 to 230 mils) of 75% resin, reinforced
with chopped strand mat (powder binder only).
Finally, the corrosion barrier is backed with a
structural laminate that provides the strength
and stiffness of the overall corrosion-resistant
composite structure.
Because many of the variables that affect the
performance of a laminate are beyond Ashland’s
control, no warranty concerning the use of
DERAKANE and DERAKANE MOMENTUM
epoxy vinyl ester resins can be made. However,
the service conditions shown in this bulletin are
believed to be well within the capabilities of
DERAKANE epoxy vinyl ester resins when
laminates are properly designed, fabricated,
and installed.
For the design of FRP equipment, prospective
users of DERAKANE resins should refer to the
appropriate industry standards and design
guidelines.
