Water Based Anti-Vibration Demoulding Rubber Mold Release Agent
Product Description
Lubekote 9421A is a high-performance, semi-permanent rubber mold
release agent engineered specifically for demanding molding
operations, particularly in the production of anti-vibration
components and rubber-to-metal bonded parts. This advanced formula
creates an exceptionally durable, protective film on the mold
surface, facilitating numerous release cycles before a
reapplication is needed. As a water-based solution, it is an
environmentally conscious choice that eliminates volatile organic
compounds (VOCs) without compromising on performance. Its
non-transferring nature ensures that the final molded rubber parts,
especially critical anti-vibration bushings and mounts, remain
uncontaminated and of the highest quality, with no visible knit
lines or surface defects.
Key Features & Advantages
Superior Semi-Permanent Release: Significantly reduces downtime by
providing multiple releases per single, thin application, boosting
production efficiency.
Ideal for Anti-Vibration Rubber: Specifically formulated to handle
the complex geometries and high-performance requirements of molding
rubber-metal bonded parts and other vibration-dampening components.
Water-Based & VOC-Free: A safer solution for the workplace and the
environment, aligning with stringent regulatory standards.
Minimal Transfer: Ensures a clean release that does not contaminate
the part surface, which is crucial for subsequent painting,
plating, or bonding operations.
Eliminates Knit Lines: Promotes complete material flow within the
mold, resulting in finished products with flawless surface
aesthetics and structural integrity.
Easy Application: Ready-to-use formula that can be easily applied
by spraying or brushing. For certain applications, it can be
diluted with deionized water.

Frequently Asked Questions (FAQ)
Q: How is Lubekote 9421A applied for best results?
A: Ensure the mold is clean and free of previous contamination.
Stir the product well before use. Apply a thin, even coat via a
spray gun or brush. Allow the water carrier to fully evaporate
(leaving the dry release film) before introducing the rubber
compound into the mold and beginning the production cycle.
Q: Can Lubekote 9421A be diluted?
A: Yes. While it is ready to use straight from the container, it
can be diluted with 1-3 parts deionized water to ensure a thinner
film and smooth release for specific applications. Always test a
diluted mixture first.
Q: Why is it recommended for anti-vibration rubber parts?
A: These parts often involve complex rubber-metal bonding. Lubekote
9421A provides a reliable, clean release that protects both the
mold and the sensitive metal surfaces, preventing rejects and
ensuring the structural integrity of the bonded component. Its
non-transfer characteristic is vital for this process.
Q: What are the storage conditions for this release agent?
A: Store in a cool, dry place and keep the container tightly
sealed. Most importantly, do not allow the product to freeze, as
this can compromise its efficacy. Use within the 12-month shelf
life.
Q: Is this product safe to use?
A: Lubekote 9421A is designed for industrial use. Avoid prolonged
skin contact with the concentrated product. Wear appropriate
protective equipment. In case of accidental contact with eyes,
rinse immediately with plenty of water.
