TR-920
MULTI-PULL
LIQUID SEMI- PERMANENT RELEASE
DESCRIPTION:
TR-920 is a high-temp multiple capability semi-permanent release coating which cures under atmospheric conditions,
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
Injection molded parts
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.
NOTE: Recommend use of TR-910 SEALER on new or repaired molds, more porous or rough mold surfaces for
maximum performance of the 900 SERIES MULT-PULL RELEASES.
