®
PMR family; primarily for closed molding of
abrasive or low draft parts.
Benefits
HAPs Free*
High thermal stability
Easy to apply
Multiple releases between applications.
Reduces labor time and cost
* HAPs are not formula constituents of this product.
Standard manufacturing processes may result in trace
quantities [<0 .1%] of HAPs.
Chemlease
®
solvent carriers contain no Class I or II
registered ozone depleting substances
Mold Preparation
1. Clean mold surface to remove all traces of waxes,
release agents and sealers.
2. Clean mold with Chemlease
®
Mold Cleaner EZ.
3. Apply the appropriate Chemlease
®
Sealer to new or
porous molds (contact a Sales Rep or Distributor for
details).
Application for base coats:
1. Mold surface must be thoroughly cleaned to remove all
traces of wax, release agents, and other sealers.
2. Surface should be dry and free of contaminants.
3. Saturate clean cotton cloth (not dripping) and wipe on
a smooth continuous film. Apply no more than 0.6 meter²
at a time.
4. When the film begins to evaporate at the edge, wipe
the surface with a second clean dry cotton cloth. Use a
circular motion from the outside, working inwards until
film is left dry and clear. See Notes.
5. Repeat above procedures until entire mold surface has
been covered.
6. Apply 4-5 coats, allowing 15 minutes between each
complete coat.
7. Allow 30 minutes for full cure. Proceed with production.
Notes:
Time will vary with room and mold temperature. Wipe off
as the solvent begins to evaporate. If the release agent is
left on too long, you may notice some smearing or
streaking. To remove the smear or streak, rub the
affected area with the recommended Chemlease
®
release agent, then simply remove the excess sooner
than you had before.
Touch up coats:
Reapply one light coat as required and cure as for final
coat.
Important
The recommended number of coats and cure times are a
general guideline found to be more sufficient in a broad
spectrum of molding conditions. When molding products
with extreme geometries or experiencing low-humidity
conditions in the shop, the customer may find the need to
extend the cure time between coats and increase the
number of coats applied to the mold. The efficiency of a
release film is best determined through a combination of
tape tests and experimentation."
Packaging

Storage
Do not store above 50°C. Keep container tightly sealed to
