PRODUCT DESCRIPTION
LOCTITE
®
FREKOTE 44-NC™ provides the following product
characteristics:

Application Temperature 13 to 60 °C
Specific Benefit ● Better mold utilization
● Non-contaminating transfer
● No mold build-up
● lower mold maintenance costs
LOCTITE
®
FREKOTE 44-NC™ is a release agent where a
non-transferring release is necessary. This semi-permanent,
non-migratory release system chemically bonds to the mold
surface to form a micro thin film which is stable at temperatures
exceeding most molding processes. LOCTITE
®
FREKOTE
44-NC™ can be used for the release of epoxies, polyester
resins, thermoplastics, adhesives, and rotationally molded
plastics.

GENERAL INFORMATION
This product is not recommended for use in pure oxygen
and/or oxygen rich systems and should not be selected as
a sealant for chlorine or other strong oxidizing materials.
For safe handling information on this product, consult the
Safety Data Sheet (SDS).
Mold Preparation
Cleaning:
Mold surfaces must be thoroughly cleaned and dried. All traces
of prior release must be removed. This may be accomplished
by using Frekote
®
PMC or other suitable cleaner. Frekote
®
915WB™ or light abrasives can be used for heavy build-up.
Sealing New/Repaired Molds:
Occasionally, green or freshly repaired molds are rushed into
service prior to complete cure causing an increased amount of
free styrene on the mold surface.
Fresh or "production line" repairs, new fiberglass and epoxy
molds should be cured per manufacturer's instructions, usually
a minimum of 2 -3 weeks at 22°C before starting full-scale
production.
Fully cured previously unused molds should be sealed before
use. This can be accomplished by applying one to two coats
of an appropriate Frekote
®
mold sealer, following the
directions for use instructions.
Allow full cure of the appropriate Frekote
®
mold sealer before
you apply the first coat of LOCTITE
®
FREKOTE 44-NC™ as
outlined in the directions of use.
Directions for use:
1.
LOCTITE
®
FREKOTE 44-NC™ can be applied to mold
surfaces at room temperature up to 60°C by spraying,
brushing or wiping with a clean lint-free, cloth. When
spraying ensure a dry air source is used or use an airless
spray system. Always use in a well ventilated area.
2. Wipe or spray on a smooth, thin, continuous, wet
film. Avoid wiping or spraying over the same area that
was just coated until the solvent has evaporated. If
spraying, hold nozzle 20 to 30cm from mold surface. It is
suggested that small areas be coated, working
progressively from one side of the mold to the other.
3. Initially, apply 4 to 6 base coats allowing 10 to 15 minutes
between coats for solvent evaporation .
4. Allow the final coat to cure for 3 hours at 22°C and can be
shortened by baking the mold for only 15 minutes at 100
to 150°C.
5.
Maximum releases will be obtained as the mold surface
becomes conditioned to LOCTITE
®
FREKOTE 44-NC™
. Performance can be enhanced by re-coating once, after
the first few initial pulls.
6. When any release difficulty is experienced, the area in
question can be "touched-up" by re-coating the entire
mold surface or just those areas where release difficulty is
occurring.
7.
NOTE: LOCTITE
®
FREKOTE 44-NC™ is moisture
sensitive, keep container tightly closed when not in use.
The product should always be used in a well ventilated
area.

8. Precaution: Users of closed mold systems (rotomolding)
must be certain that solvent evaporation is complete and
that all solvent vapors have been ventilated from the mold
cavity prior to closing the mold. An oil-free compressed air
source can be used to assist in evaporation of solvents
and ventilation of the mold cavity.
Mold Touch up
Touch up coats should only be applied to areas where poor
release is noticed and should be applied using the same
method as base coats. This will reduce the possibility of
release agent or polymer build-up. The frequency of touch ups
will depend on the polymer type, mold configuration, and
abrasion parameters.
