TR-900
MULTI-PULL
LIQUID SEMI-PERMANENT RELEASE
DESCRIPTION:
TR-900 is a high temp semi-permanent release coating which dries rapidly under atmospheric conditions, bonding an
ultra thin clear release film to the mold surface. Exceptional multiple releases per application for various polyester
molding processes and other resin fiberglass fabrication.
PRODUCT FEATURES:
Excellent hi-temp properties (Thermally Stable 750 F )(400 C)
Multiple release per application
Rapid cure time speeds production cycle
No pre-release or transfer
Wipes to high gloss finish
Easily recoats without build-up
SUGGESTED USES: An ef fective multiple release agent for the FRP and related molders
Open mold hand or spray lay-up
Compression molding
Injection molded parts
Vacuum bag
Resin transfer molding (RTM)
APPLICATION: Always use and apply with a clean, lint-free 100% cotton white cloth (no synthetic blends). Clean
mold surface thoroughly of all previous release agents and sealers using the TR-905 mold prep solvent. Surface
should be completely dry and free of any contaminates. Apply TR-900 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. (Do not apply heavily or excessively
wet). 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 application overlapping the previous small area until the entire
mold surface is complete. Repeat this for 3-4 coats to the entire mold surface allowing minimum 15 minutes
between coats and 30 minutes after final coat. Maximum results obtained if mold is allowed to stand overnight
before first use. A 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. Wipe with a clean dry cotton cloth as noted in wipe application.
NOTE: Recommend use of TR-910 SEALER on new or green or repaired molds, more porous or rough mold
surfaces for maximum performance of the TR-900 RELEASE.
