bonding a durable thin clear release coating to the mold surface. Multiple releases per application for polyester, epoxy,
polymides, BMC, SMC, and various other advanced resins in fiberglass or graphite composite molding processes.
PRODUCT FEATURES:
Excellent hi-temp properties (Thermally Stable to 900 F/482 C)
Multiple releases per application
Ease of application and fast cure time
No pre-release or transfer
Wipes to a gloss finish
Easily recoats without build-up
SUGGESTED USES:
An effective multiple release agent for the FRP and related molders.
Open mold hand or spray lay-up
Compression molding

Vacuum bag
Resin transfer molding (RTM)
APPLICATION: Always use and apply with a clean, lint-free all cotton cloth (no synthetic blends). Clean mold surface
thoroughly of all previous release agents and sealers using the TR-905 mold prep solvent. Mold surface should be completely dry and free of any contaminates. Apply TR-920 by wiping a thin wet coat onto a small area (approx. 3 x 3
ft.) of the mold surface starting at an end point of the mold. While the release film is still wet, wipe gently with another clean, dry, cotton cloth, turning and changing cloths as required for proper drying. Avoid excessive hard rubbing or
wiping of the treated surface, which ensures a more uniform and effective film deposit. Apply each subsequent release coat overlapping the previous small area until complete mold surface is covered. Repeat this for 3-4 coats to the entire
mold waiting 15-20 minutes between coats. Cure time of the final release film at room temperature (75 F/24 C ) is
approximately 30 minutes. Additional touch-up coat is recommended for the first 2-3 initial releases to maximize mold
conditioning and durability. When spraying, use a dry air source or airless spray, applying in a thin continuous smooth
film, avoiding excess flooding or runs. Polish wipe with a clean, dry, cotton cloth as noted in wipe application.

Filament winding/Rotational Molding
APPLICATION:
Clean mold surface thoroughly of all previous sealers and release agents using TR-905 mold prep solvent. Light
abrasive compounding may be necessary to remove the various types of release agents or sealers previously used.
After compounding, first water wash and wipe dry to remove compound residue. Then completely clean the mold
surface with TR-905 mo ld prep solvent.
Apply a thin wet film to mold surfaces either by wipe or spray. Use an ALL-COTTON cloth when wiping to avoid possible
binders in other fabrics dissolving from solvent carriers. Use an airless spray unit or a dry air source when spraying
holding spray nozzle approximately 8-10 inches from mold surface. Start at one end of a mold working small areas or
sections to the other end ensuring a thin wet film is applied to entire mold surface. Secondary polish step is not required.
If desired gloss is reduced after application, lightly polish with 100% cotton cloth after final coat.
For initial break-in, apply 3-5 coats. Allow 5-10 minutes between each application and 10-15 minutes after final
application for solvent release and cure. Recoat for the first 2 -3 initial pulls or de- molding to aid full conditioning and
mold life. Recoat will vary depending upon mold design or materials. Apply again at first sign of release difficulties. Use
the TR-910 sealer if mold surface is porous, less smooth, or to provide improved initial release on new or green and
repaired molds.
