Stickfast 354 brominated Vinyl
Ester Resin are polymerized
by free-radical initiating catalysts.
The most commonly used catalyst
systems are similar to the one
used with other grades of vinyl
ester resins.

CAUTION: Accerator and promoter
should never be mixed with catalyst
as this would cause explosion.
The accelerator and promoter
should be blended into the resin
first. The catalyst should be
added just before use.

AREAS OF APPLICATION
Stickfast 354 Borminated
Vinyl Ester Resin shows
chemical resistance properties
similar to Stickfast 353,
but is have much higher
degree of fire retardancy
derived from synergetic
effect of antimony compounds
with the bromine from
resin backbone. Stickfast
354 has similar applications
of Stickfast 354, but
where transparency of
the moulding in not required.
Stickfast
354 Brominated Vinyl
Ester Resin can be successfully
used in FRP duct work,
stacks and stackliner
applications, equipments
specified to handle
mixtures of air and
not gases or potentially
flammable liquids, building
panels and flooring
compounds, where a very
high degree of fire
resistance is needed.
Stickfast
354 can also be used
in military marine market
for the production of
high quality light weight
Navy Craft.
