Product Details


Universally applicable liquid external release agent, solvent-based and with short drying times.

  • Heat resistant up to 140 °C
  • Solvent-based
  • Multi purpose-product
  • Semi-permanent: multiple releases per application
  • Raise mould temperature to increase slip effect
  • Silicone-free formulation
  • Short drying time
  • Renders time-consuming wax and polishing cycles unnecessary

The use of this product eliminates the need for a repeated time-consuming waxing and polishing, as a single application allows, after some starting time that demands frequent treatment of the mould, several demouldings.

Release agent Semiperm™ Monofilm forms a monomolecular film that adheres to the mould and does not show any affinity to the moulded parts.

Release agent Semiperm™ Monofilm is silicone-free and suited for the purpose of processing of thermosets like polyester (cold and hot moulding), epoxy and phenolic resins. In particular when the processing takes place at elevated temperatures (> 50 °C), flawless results are obtained.

Prior to the first application of release agent Semiperm™ Monofilm, the moulds have to be cleaned thoroughly from residues of dirt and former release agent. The next step is to apply release agent Semiperm™ Monofilm as an even, thin film and allow it to dry. The application can be done either by spraying, wiping or brushing. After a short flash-off time of 1-2 minutes the mould surface can be polished with a lint-free cotton cloth to a high gloss finish. Repeat this procedure 4-5 times at new moulds. Before starting the production, ensure that the film is absolutely dry. Release agent Semiperm® Monofilm should be stirred up or shaken prior to use.

25-30 g/m²

Please note:
If used in the processing of prepregs, we highly recommend to do preliminary testing, due to the often high pressure used there is a risk that the release agent is going to be damaged mechanically. Thus, the demoulding can be made difficult or even impossible. The same applies to press-moulded parts (mould and counter mould), when processed with high pressure.
