Styrenated
Phenols
Styrenated Phenol (SP) is a clear, yellow, viscous
liquid and is supplied in 3 grades-
mono-, di-, or tri- styrenated phenol.
It
is a non-staining and non-discoloring anti-oxidant
for dry rubber and latex compounds.
It acts as a stabilizer in polymers in combination
with other phosphite or phenolic anti-oxidants.
SP
particularly finds use in white and colored rubber.
The rubber articles that use Styrenated phenol are
Hawaii Sheets and Straps, Rubber tubing, Conveyor
belts covers and latex dipped products (such as industrial
gloves, surgical gloves, feeding bottle teat). Other
products such as balloons, hot water bottles, injection
bottle caps, rubber rollers and Footwear related items
(such as Micro cellular sheets, Resin rubber sling,
Canvas upper shoe) use Styrenated Phenol.
SP
emulsion is used in the manufacture of latex foam,
latex sprays for coir treatment (Coir foams).
SP
can be ethoxylated using Ethylene oxide. The ethoxylated
SP finds use as an emulsifier in the pesticide industry.

EPOXY RD
EPOXY RD is an organic liquid of low viscosity and
useful in epoxy resin systems. It is completely miscible
with all liquid epoxy resin and can therefore be blended
in any concentration consistent with the physical
properties required by the end-user.
It
can be considered a partial replacement for conventional
hardners such as polyamines, aromatic amines and polyamides.
Resins containing this speciality chemical may be
stored in closed containers for several months without
appreciable change in viscosity.
EPOXY
RD improves the compressive strength and dimensional
stability of the epoxy castings. In epoxy potting
compound, it enhances electrical properties and gives
superior bond strength which makes it of value in
adhesive applications.
Conventional
reactive diluents like Butyl Glycidyl Ethers (BGE)
are more expensive and there is limitation to the
quantity, which may be added before the chemical and
physical properties start to deteriorate.
Absolute
viscosity control comes through the addition of a
reactive diluent like EPOXY RD.
