High-Performance Polyurethane Release Agent Concentrate for Rigid
Foam
Lubekote 9129E is a premium-grade, solvent-dilutable PU release
agent specifically engineered for the demanding production of
polyurethane rigid foam. This advanced concentrate is formulated to
provide unparalleled mold release performance, ensuring flawless
demolding and a superior surface finish on finished parts. It is
the go-to solution for manufacturers seeking to enhance efficiency,
reduce downtime, and achieve consistent, high-quality results in
their rigid PU foam operations.
Product Overview & Description
As a specialized Polyurethane release agent, Lubekote 9129E tackles
the unique challenges of rigid foam molding. Its powerful formula
prevents the foam from adhering to the mold surfaces, facilitating
easy and clean part ejection every time. This product is supplied
as a concentrate, offering flexibility and cost-effectiveness by
allowing users to dilute it to the precise concentration required
for their specific application and mold geometry. Its exceptional
performance helps protect valuable molds from wear and tear,
extending their operational life.
Key Features & Advantages
Exceptional Release for Rigid Foam: Expertly formulated to provide
reliable, consistent release for even the most complex rigid
polyurethane foam parts, eliminating tearing or sticking.
No Build-Up Formula: Prevents the accumulation of residue on the
mold surface, significantly reducing downtime for mold cleaning and
maintenance.
Superior Surface Finish: Contributes to the production of rigid
foam parts with a smooth, blemish-free surface, ready for further
processing or painting.
Easy Application & Low Odour: Its liquid concentrate form allows
for easy dilution and application via spraying or wiping. The
low-odour formulation improves the working environment for
operators.
Cost-Effective Concentrate: Dilution flexibility (typically 10:1 to
30:1) means a small amount of concentrate goes a long way, reducing
overall cost per application.
Long Shelf Life: Stable for up to 24 months from the date of
manufacture when stored correctly in its original, sealed
container.

Application Guidelines
For optimal results, dilute Lubekote 9129E with a recommended
solvent such as naphtha or heptane. A general dilution ratio is
between 10:1 to 30:1 (solvent:agent). Always ensure the mold
surface is meticulously clean and free from previous contamination.
Apply at least two thin, uniform coats at the process temperature,
allowing a short drying time between applications. For continuous
production cycles, a light maintenance coat can be reapplied as
needed to sustain perfect release performance.
Handling Precautions
For industrial use only. Avoid prolonged skin contact with the
concentrate. Always use appropriate personal protective equipment
(PPE), including gloves and safety glasses. In case of eye contact,
rinse immediately with copious amounts of water for several minutes
and seek medical attention.
Frequently Asked Questions (FAQ)
Q: What type of polyurethane is Lubekote 9129E used for?
A: Lubekote 9129E is specifically formulated and demonstrates
excellent performance in releasing polyurethane rigid foam. It is
not recommended for flexible foam applications.
Q: How do I dilute Lubekote 9129E?
A: It is a concentrate that must be diluted with a solvent. We
highly recommend using naphtha or heptane. A general starting
dilution ratio is between 10:1 to 30:1 (solvent:agent). The exact
ratio should be optimized for your specific mold design and process
conditions.
Q: Does this product leave residue on my molds?
A: No. A key advantage of Lubekote 9129E is its "no build-up"
formulation. This characteristic ensures your molds stay cleaner
for longer, reducing maintenance downtime and preserving mold
detail.
Q: What is the shelf life of this PU release agent?
A: When stored in a tightly sealed container in a cool, dry place,
Lubekote 9129E has a shelf life of 24 months.
Q: Is this product easy to apply?
A: Yes. Its liquid consistency makes it easy to dilute and apply
using standard industrial spray equipment or a cloth for wiping,
ensuring thin, even coverage.
