|
Superior
Engineering |
| Our process is
built on sound principles of chemical engineering design.
To maintain premium
quality our process is carried out in glass lined reactors
and glass extraction units. We use a dedicated plant
and a separate building unit. |

Safety
Requirements |
| Please see the
MSDS for health and safety requirements. |
| All peroxides
are high energy compounds and are inherently unstable.
Care should, therefore, be taken in handling and storage of
these compounds. |
| Kerox MEKP-PHF-60509 is
flammable, although the risk of auto-ignition under normal
conditions is small due to its high flash point. Once
ignited it will burn slowly at first, then vigorously, and
finally explode. |
| Kerox MEKP-PHF-60509 may
undergo slow decomposition at room temperature with
evolution of gaseous products which readily support
combustion if ignited. The gassing will also lead to
pressure build-up leading to a possible bursting of the
container. |
| Kerox MEKP-PHF-60509 is
also catalytically decomposed by certain metallic, organic,
or acidic materials. |
| |
|
Handling Spills |
| Care must be
exercised while mopping up spillages on the production
floor. Cotton based rags or other mopping material
may, at times, be contaminated with accelerators or solvents
like acetone, which are commonly used for cleaning
operations. For the same reason, rags contaminated
with catalyst should not be thrown carelessly into waste
bins where, even in the absence of an accelerator, it may
undergo spontaneous combustion. The best way to
dispose off the contaminated rags is by burning under
controlled conditions. Each country has different
regulations and we urge you to consult accordingly for disposal of such waste. |
| |
|
Handling Fire |
| In the event of
an accidental fire immediately call your local emergency
response governmental department. As a first response
in such situations please be advised that conventional
carbon dioxide type extinguishers will be ineffective as the
catalyst produces its own oxygen to support combustion.
In such circumstances, the burning catalyst must be cooled
with water, wet-sand or earth, foam based extinguishers or,
if available, dry ice. All effort must be made to put out
the fire before it goes out of control. |

Practical Safety
Guidelines |
 Considering the
relatively high hazard of organic peroxides, the
safety-in-use record of Kerox MEKP-PHF-60509 has been most
satisfactory. However, careful attention must be given
to the following precautions while storing and handling of Kerox MEKP-PHF-60509. |
 |
Store in a
cool, dark place. |
|
|
Avoid rough
handling. |
|
|
Keep away
from direct sunlight, steam pipes, naked flame, and
other sources of heat. |
|
|
Smoking
should be strictly prohibited in the vicinity. |
|
|
All
electrical installations should be flame proof type and
all wiring must be concealed. |
|
|
Avoid
contamination with metallic, organic, or acidic
materials, and in particular metal soaps and
accelerators. |
|
|
Avoid
contamination with solvents like acetone which may react
to form explosive mixtures. |
|
|
Do not store
accelerators and resins along with the catalyst. |
|
|
Avoid
contact with flammable materials such as wood, paper,
fabrics, saw dust, and other cellulosic materials. |
|
|
Keep the
catalyst in original containers. Do not return
unused material to the container. Keep the
container closed at all times to avoid contamination. |
|
|
Vent the
catalyst periodically to release any internal pressure. |
|
|
Large
quantities of catalyst, above 50 Kg, must be stored in
an isolated building away from other combustible
materials. |
|
|
| |
| Why MEKP-PHF-60509? |
| MEKP available in the Indian market has
traditionally been based on plasticizers and it will contribute to
about 7500 ppm of phthalates when used at 2% by weight on the
weight of the
unsaturated polyester resin. |
| At a 7500 ppm contribution of phthalates in
the finished product, it will fail the
Oeko-Tex 100 Class 1
Standard and also will not comply with
REACH EU Regulations.
Though Oeko-Tex and REACH have restrictions on certain
phthalates, buyers and importers in the European Union have
restrictions on other phthalates. |
| Kerox has solved the problem
by engineering a new breed of MEKP products that is free
from all phthalates. |
| Manufacturers of products
using unsaturated polyester resins will be able to
exclude any contribution to phthalates
originating from MEKP, by using Kerox MEKP-PHF-60509 in
their process. |
| |
| Certified Quality |
| Kerox has been
awarded the ISO 9001:2000 certification by UKAS (UK) and
ANSI-RAB (USA) for the manufacture of MEKP-PHF-60509 Methyl Ethyl Ketone Peroxide Catalyst. |
| |
| Recommendations |
| Gel time is a
function of the type and quantity of MEKP catalyst used,
Accelerator used, resin system, and the ambient temperature.
You can adjust these variable to alter the gel time.
Please see
literature for further insights. |
| |
|
Storage and
Handling |
| Kerox MEKP-PHF-60509
shows no loss of activity after 3 months if kept at 25o
C. When stored above this temperature it may suffer a
slight loss of activity. Storage stability can be
considerably improved by storing at lower temperatures.
The optimum storage temperature is considered to be 10o
C. The peroxide may crystallize below 10o C
forming shock-sensitive crystals. |

First Aid
Measures |
 Kerox ME-50 is
a powerful oxidizing agent and care must be taken to avoid
contact with skin, eyes, and clothing. Protective
gloves must be worn when handling the catalyst. |
|
Skin - Immediately remove any
contaminated clothing. Wash contaminated area with
soap and a running stream of water for a minimum of 15
minutes. If irritation, or burns, or adverse symptoms
develop seek medical attention. |
|
Eyes - Serious damage can occur
if the catalyst enters the eye. As a first aid
measure, if wearing contact lenses, remove them immediately.
Flush eyes with water for at least 15 minutes.
Separate the eye lids with your finger and continue thorough
flushing. If irritation, or burns, or adverse symptoms
develop seek medical attention. |
|
Ingestion - Do not induce
vomiting. Immediately seek medical attention and
consult a physician and a poison control specialist. |
|
Inhalation - Remove affected
individual to fresh air. If coughing, breathing
becomes labored, irritation develops, or other symptoms
develop, seek medical attention at once. Even if
symptoms develop several hours after exposure consult a
physician. |
