Release spray Semiperm™ Monofilm, 400 ml

    silicone-free, up to 140 °C

    Release spray Semiperm™ Monofilm, 400 ml

    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 repeated time-consuming waxing and polishing, as a single application allows, after some starting time that demands the frequent treatment of the mould, several demouldings.

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

    Release spray Semiperm™ Monofilm is silicone-free and suited for the purpose of the 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.

    Release spray Semiperm Monofilm should be shaken prior to use.

    The picture shows the importance of homogenizing liquid release agents well before processing:

    1.) Thoroughly stirred or shaken

    2.) After a few days of rest, the active ingredient settles and the solvent separates to the surface. If the two are not thoroughly mixed again before processing, there is a risk that almost only solvent will be applied during application. The separating effect is then correspondingly poor or does not occur at all.

    Prior to the first application of release spray Semiperm™ Monofilm, the moulds have to be cleaned thoroughly from residues of dirt and former release agent. The next step is to apply release spray Semiperm™ Monofilm as an even, thin film and allow it to dry. 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.

    25-30 g/m²

    Please note:
    If used in the processing of prepregs, we highly recommend doing 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.

    Important note on substrates:
    This product contains solvents based on hydrocarbons (see under Additional Information --> Safety Data Sheet). It also contains a small amount (< 2 %) of aromatic hydrocarbons. Some surfaces made of plastic (e.g. polycarbonate, Plexiglas®, various varnishes, putties) are dissolved by it so that an impression cannot be taken. It is essential to check this before use, either by referring to resistance lists for the materials or by carrying out a preliminary test.

    For sensitive surfaces, we alternatively recommend PARTALL® Coverall Film PVA from Rexco.
