Chemlease
70 EZ
Release Agent
Description
Chemlease
70 EZ is a unique semi- permanent mold
release system developed specifically for the composites
industry, for use where a high quality finish is required.
Benefits
HAPs free*
Multiple releases between applications
Easy to apply
Eliminates the use of wax
Reduces labor time and costs
Provides excellent gloss
High temperature stability
Does not build up on the mold surface
Minimal transfer to molded part
* 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. Mold surfaces should be thoroughly cleaned to remove all traces
of wax, release agents, sealers and buffing compounds.
2. Do a final cleaning of mold surface with
Chemlease
Mold Cleaner.
3. Seal mold with the appropriate Chemlease
Sealer.
Application
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 a few square feet 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, and then simply remove the excess
sooner than you had before.
Test To Ensure Proper Application
Attach a small strip of masking tape to different areas of the mold.
There should be very little resistance when removing the tape if
proper release is applied. Compare to an untreated mold. (Tape
should adhere to untreated mold).
Touch-Up Coats
Once in production the release film will begin to wear. Rather than
applying a touch-up coat once the parts begin to stick, it is better to
do preventative maintenance. For example, if trials determine that
20 releases are obtainable between touch-up coats, it is better to
reapply a touch-up coat after every 15 cycles or at the end of every
second shift. The above-described action will keep the molds in
production longer and help establish a routine of quality
preventative maintenance.
Important
The recommended number of coats and cure times are a general
guideline found to be more than 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.
Storage
Do not store at temperatures above 49 C/120 F. Keep container
tightly sealed to prevent evaporation and/or contamination. If
stored in cold temperatures allow warming to room temperature
before using.
