STICKFAST
341 BISPHENOL POLYSTER RESIN
|

GENERAL
DESCRIPTION |
| |
Stickfast
341 is a modified Bisphenol Fumerate Polyester
resin having superior chemical resistance
to a wide range of industrial effluents,
acids, Alkali, Salt and Organic solvents
at elevated temperatures, Because of the
moderate viscosity of Stickfast 341 Resin
rapidly wets glass fibre in the form of
cloth, mat or chopped fibre to produce laminates
at elevated temperatures. Stickfast 341
is an ideal material for combating corrosion
problems and is used in a wide range of
corrosion resistance aapplications like.
1. Electroplating Industries
2. Paper and Pulp Industries
3. Fertilizer Industries
4. Battery Container manufacturing
5. Transportation and Storage of various
Chemicals.

CURING
CHARACTERISTICS |
| |
Stickfast 341 is cured by free radical
initiating catalysis with suitable
accelerators to promote rapid and
complete curing.

Geltime
will vary with temperatures and
the amount of catalyst Accelerator
and promoter used.
CAUTION: Accelerator should never
be mixed with catalyst as this would
cause explosion. The accelerator
should be blended into the resin
first. The catalyst should be added
just before use.

(The
specimens for testing are
cured for 24 hours at Room
temperature followed by Post
Curing for 4 hours at 80 °C).
POST
CURING REQUIREMENTS
Satisfactory laminates for
many applications can be
made by curing the laminate
at ambient temperatures.
However for achieving optimum
properties the laminate
should be post cured for
a period of 4 hours at 80
°C.
the Post curing is most
effective when carried out
immediately after the 24
hours ambient temperature
cure.
