TRS release spray is a silicone-free spray release agent for clean demolding of epoxy, polyester, and polyurethane resins — temperature-resistant up to +120 °C, fine spray mist also for complex geometries.

Release sprays for composite and reaction casting applications — wax- and silicone-based spray release agents for clean demolding of polyester, epoxy, and polyurethane resins in model making, boat building, automotive body construction, and industrial fabrication. TRS release spray is tailored to specific industrial and workshop applications — the key properties and areas of use are listed below.

Silicone-free + temperature-stable up to +120 °C

TRS Release Spray is a silicone-free spray release agent for clean and reliable demolding of epoxy, polyester, and polyurethane resins. Specifically developed for smaller and quick moldings, with a fine spray mist that reliably reaches even complex geometries. Coverage approx. 13–18 m² per 400 ml can. Extends the service life of silicone molds.

Processing

1
Prepare the mold
Mold clean, grease-free, and silicone-free. Seal absorbent substrates beforehand. For new molds, repeated waxing is recommended — micropores are closed.
2
Condition the release agent
Bring the aerosol can to room temperature (approx. 20 °C) before use — spraying when cold results in uneven layers.
3
Shake the aerosol can
Stir thoroughly before and during use — active ingredients must be evenly distributed in the propellant gas.
4
Spray from a distance of 20–30 cm
Apply slowly and evenly in a thin layer — all mold areas must be wetted by the release agent.
5
Flash-off 10–60 minutes
Drying time varies by product — solvents must evaporate completely. For wax-based release sprays, optionally polish with a soft cotton cloth (caution — friction generates heat; do not polish away the release film).
6
Re-spray as needed
If the release effect diminishes, repeat the process. The release agent film builds up in the mold after repeated use — periodic cleaning with a release agent remover is necessary.

Frequently Asked Questions about Trennspray TRS

Application and compatibility questions from practice — answered by SILITECH.

Trennspray TRS: Silicone-free spray release agent for clean demolding of epoxy, polyester, and polyurethane resins — temperature-resistant up to +120 °C, fine spray mist also for complex geometries. Main applications: model making, industrial prototyping, boat building.

For polyester (UP) and epoxy resin (EP), wax-based sprays are standard (Neukadur P6, Wax Release Spray G&P, Release Spray TRS) — silicone-free, they leave the component paintable/glueable. For difficult polyurethane demolding with high requirements or multiple cycles, the silicone-containing ACHEM SG-1001S offers the highest release reserve. For each application: thin, even coat, allow to flash off — often repeated waxing before the first pour on new molds.

No. Silicone sprays leave a water-repellent silicone film that prevents the adhesion of paints, adhesives, and coatings. Do not apply to surfaces that will later be painted or overlaid, or clean thoroughly beforehand with SILISIL Silicone Remover.

Store aerosol can below +50 °C, protect from direct sunlight, keep away from ignition sources. Pressure container — do not forcibly open or incinerate, even after use. In unopened original packaging, shelf life according to SDS — observe the printed expiry date.

Polyester/Epoxy resin composites: Wax-based sprays — Neukadur P6 (UP/EP special), Wax Release Spray G&P (silicone-free, polishable up to +90 °C), Release Spray TRS (silicone-free up to +120 °C). Polyurethane challenges: ACHEM SG-1001S with highest release reserve for multiple demoldings. Food packaging: NSR Food FPS Spray with NSF M1 registration No. 155325. If uncertain about material compatibility, always perform a small test pour.
