Advanced Water-Based Semi-Permanent Release Agent for Rubber
Lubekote 9440A is a high-performance, water-based semi-permanent
release agent engineered for demanding molding operations in the
rubber industry. Specifically formulated for high-temperature
stability and minimal transfer, it is the ideal solution for
manufacturers of silicone rubber, fluorine rubber, and other
challenging compounds. This product ensures easy demolding,
exceptional surface quality, and extended mold life, making it a
superior and environmentally friendlier choice for efficient
production.
Product Overview & Description
Lubekote 9440A is a premium rubber release agent designed to
address the critical needs of modern rubber molding. Its advanced
formula creates a durable, thermally stable barrier that provides
multiple release cycles from a single application. It is primarily
used for silicone and EPDM rubber and is exceptionally effective
for other hard-to-release elastomers like fluorine rubber (FKM) and
HNBR. As a ready-to-use, water-based emulsion, it offers
significant advantages over traditional solvent-based systems,
including no VOCs and easier handling.
Key Features & Advantages
Water-Based & VOC-Free: Eliminates harmful volatile organic
compounds, ensuring a safer workplace and reduced environmental
impact.
True Semi-Permanent Performance: Delivers multiple consistent
release cycles per application, drastically reducing downtime and
increasing production throughput.
Extremely Low Transfer: Formulated to minimize migration onto the
molded part, which prevents contamination and issues with secondary
operations like painting or bonding.
Exceptional High-Temperature Stability: The release film remains
stable and effective at temperatures up to 260°C (500°F), perfect
for high-heat curing processes.
Prevents Mold Build-Up: Its non-stick properties resist the
accumulation of residues on the mold surface, reducing cleaning
frequency and maintaining mold integrity.
Ready-to-Use Convenience: Requires no mixing straight from the
container, though it can be diluted for specific application needs.

Application Guidelines
For best results, start with a thoroughly cleaned and warm mold.
Shake or stir the product well before use. Lubekote 9440A is ready
to use but can be diluted with 1-3 parts deionized water for a
lighter coat if necessary. Apply a single, thin, and uniform coat
to the mold surface using a spray or cloth. Allow the water carrier
to evaporate completely (leaving the active release film) before
commencing the molding cycle. Reapplication is only needed after
several cycles.
Handling & Storage Precautions
For industrial use only. Avoid prolonged skin contact. Use
appropriate personal protective equipment (PPE). In case of eye
contact, rinse immediately with plenty of water and seek medical
advice. Do not allow the product to freeze, and store in a cool,
dry place.
Frequently Asked Questions (FAQ)
Q: What types of rubber is Lubekote 9440A designed for?
A: It is primarily and exceptionally effective for silicone rubber
and EPDM. It is also highly recommended for other
difficult-to-release elastomers such as fluorine rubber (FKM) and
HNBR.
Q: Is this a semi-permanent release agent?
A: Yes. Lubekote 9440A is formulated to provide multiple release
cycles from a single application, classifying it as a
high-performance semi-permanent release agent that boosts
productivity.
Q: Does this rubber release agent require dilution?
A: It is ready to use straight from the container. However, for
certain applications or to extend coverage, it can be diluted with
1-3 parts deionized water.
Q: What is the maximum temperature it can withstand?
A: The release film formed by Lubekote 9440A is stable and provides
excellent performance at temperatures up to 260°C (500°F).
Q: What is the main advantage of a water-based formula?
A: Being water-based means it contains no solvents or VOCs, making
it safer for operators, better for the environment, and often
compliant with strict air quality regulations.
