Product Description
LubeKote 9519A is a versatile, water-based release agent engineered
for the high-temperature demands of composite manufacturing,
particularly in the production of advanced components like
carbon-based composite bipolar plates. As a universal solution for
epoxy, polyester, vinyl ester, phenolic, and other thermoset
resins, it ensures flawless demolding without compromising the
critical properties of the finished part. Formulated with advanced
polymeric resins, LubeKote 9519A creates a durable,
non-transferring film that is essential for maintaining the
electrical integrity and surface quality of sensitive composite
materials. Its effectiveness in challenging processes, such as the
molding of graphite-based bipolar plates with phenolic or epoxy
binders, makes it an indispensable tool for manufacturers seeking
precision and efficiency.
Key Features & Advantages
This specialized release agent delivers significant benefits that
enhance both production outcomes and operational efficiency:
Universal Compatibility: Effectively releases a wide range of
thermoset resins, including epoxy, phenolic, polyester, and vinyl
ester, from all common mold surfaces, including steel.
Zero Contamination & No Residue: Leaves no trace on the molded
part, guaranteeing that critical functional properties like
electrical conductivity, gas tightness, and surface resistivity
remain entirely unaffected.
Extended Mold Cleanliness: Dramatically reduces mold fouling,
allowing for prolonged production runs. In applications like
bipolar plate molding, this can extend cleaning cycles to just once
per week, minimizing downtime.
Water-Based & Odorless: Provides a safe and environmentally
friendlier alternative to solvent-based agents, with no strong
odors, improving workplace conditions.
High-Temperature Stability: Performs reliably in demanding thermal
cycles, from application at 60-70°C through curing at 150°C,
ensuring consistent release performance.
Durable Film & Multiple Releases: Its robust film-forming
capability often allows for several demolding cycles per
application, reducing material consumption and increasing
productivity.

Application Guidelines for Bipolar Plate Production
For optimal performance in a bipolar plate molding process:
Mold Preparation: Ensure the steel mold is perfectly clean, dry,
and free from all previous residue.
Application: Apply a thin, even coat of LubeKote 9519A via spray
gun onto the mold surface at a temperature of 60-70°C.
Drying/Curing: Allow the agent to dry completely. The mold is then
heated to the processing temperature of 150°C.
Molding Process: Proceed with the standard process: loading the
graphite/phenolic (or epoxy) compound, applying heat and pressure
for the 20-minute cure cycle.
Demolding: Cool the mold to approximately 70°C. The part will
release cleanly and easily, ready for the next cycle. A new coat is
typically only required after multiple productions.
FAQ (Frequently Asked Questions)
Q: How does a release agent like LubeKote 9519A benefit the
production of composite bipolar plates?
A: It is critical for achieving a perfect surface finish and
maintaining the plate's functional properties. By preventing the
composite from sticking to the steel mold, it ensures easy
demolding without leaving any residue that could degrade electrical
conductivity or gas tightness.
Q: Why is the "no residue" property so important?
A: Any residual film on the bipolar plate can act as an insulator,
severely compromising its electrical performance and conductivity
in the final application, such as a fuel cell or battery. LubeKote
9519A is proven to have zero transfer, safeguarding these vital
characteristics.
Q: Can this agent really extend mold cleaning cycles to a week?
A: Yes. Its formulation is designed to resist build-up. In the
described bipolar plate process, the minimal fouling allows for
sustained production over many cycles, significantly reducing the
frequency of cleaning shutdowns.
Q: Is it suitable for use on high-temperature steel molds?
A: Absolutely. LubeKote 9519A is specifically formulated to
withstand the thermal stress of processes where molds are heated to
150°C and above, providing a stable and reliable release barrier.
Q: How does being water-based make it a better choice?
A: Water-based agents like 9519A are safer to handle
(non-flammable), have low VOCs, and are more environmentally
friendly. They also eliminate the health and safety concerns
associated with solvent fumes, creating a better working
environment.
