RB-MO Solvent based chemical release agent

Description :

Chemical release agent suitable for mould and shutter faces prior to casting concrete in order to achieve a clean release. After removal of the formwork, the resultant concrete has a smooth hard uniform finish, with reduced incidence of blow holes. RB-MO can be applied to the formwork by spray in the form of a light uniform mist coating.

Usage :

  • RB-MO is formulated for application to plywood, timber, steel and plastic faced formwork and moulds, prior to casting concrete, to ensure a clean release.

Features and benefits :

  • RB-MO has no negative effect on the properties of concrete nor will it impair the adhesion of subsequent surface treatments when applied at the recommended coverage rates
  • RB-MO reacts chemically with cement to impart excellent release properties to treated surfaces. Concrete cast against surfaces coated with RB-MO exhibit a smooth, hard, uniform finish

How to use :

Apply before the first casting and thereafter re-apply immediately after stripping and cleaning the mould. Lightweight horticultural sprayers are ideal as RB-MO is finely atomized to give a uniform coating. Excessive application should be avoided. Alternatively, application may be made by a fine haired brush, only a very thin coating should be made and any excess removed.
If after the first application, the RB-MO is completely absorbed into new timber or plywood, a further application should be made before filling the moulds or formwork. The coverage rate for RB-MO is 30 to 70m²/liter when spray applied depending on smoothness and porosity of the formwork used.
Note:
Progressively better results are obtained on plywood and timber moulds as they become impregnated and the operatives become accustomed to working with the release agent. RB-MO in general, may be used over timber moulds. etc., which have been treated with other mould oils, providing excess has been removed.
