Solvent-based Mold Release Agent for the Polyurethane Industry
LubeKote 129E
Description:
Lubekote 9129E is a solvent-based mold release agent formulated for
the polyurethane industry. Lubekote 9129E has shown excellent
performance in releasing polyurethane single-density shoes.
Properties:
Colour: Clear liquid
Density: 0.96-1.00 g/cm³
Shelf life: 24 months
Advantages:
- Shiny surface, no greasy.
- Form a clean film and can be tightly bonded to the mold surface.
- Keep the mold clean for a longer time and reduce the frequency of
downtime.
- Ideally, multiple demolding cycles can be achieved for per
application.
Application:
For optimum performance, the surface to be treated should be clean
and free from oil or other residues. Lubekote 9129E is delivered as
a concentrate and should be diluted prior to use with solvent. The
dilution of 10-25 by volume is recommended. Optimal dilution rate
should be established for each application. Stir or shake gently
before use. When spraying the release agent, the spray gun should
be 10-20 cm away from the surface of the mold. For the cleaned
mold, it needs to be sprayed 3 times continuously, and the interval
between each time is 3-5 minutes; after the last spray of the
release agent, it is necessary to wait for the release agent to
completely dry before normal production.
Handling precautions:
For industrial use only.
Prolonged skin contact with high concentrate dilutions should be
avoided. Accidental splashes in the eye should be washed out with
copious amounts of water.
