TR-930HS
MULTI-PULL
LIQUID SEMI-PERMANENT RELEASE
DESCRIPTION:
TR-930HS is a high slip low odor fast curing multiple capability s emi-permanent mold release for use molding various
polymers (polyester, epoxy, polyamide, SMC, BMC, etc.). Excellent for difficult to release closed mold processes,
filament winding and non gel-coat polyester applications.
PRODUCT FEATURES:
High temperature properties up to 750 F (400 C)
High slip – multiple releases per application
Easy wipe on leave on or spray application
No pre-release or transfer
Durable high gloss coating
Easily recoats without build-up
USES:
Open mold hand or spray lay-up
Compression & Prepreg molding
Injection molded parts
Vacuum bag/RTM
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.
