MasterFinish RL 520

Release agent emulsion based on highly refined mineral oil providing exceptional rust protection

How does MasterFinish RL 520 work?

MasterFinish RL 520 is an oil/water emulsion. In contrast to conventional products, the ingredients ensure good working hygiene. As a very efficient release agent, it ensures excellent demoulding even with complicated formwork. The separating film that forms on the formwork after breaking the emulsion is highly effective, rain-resistant, and rust-protective. The suitability for paints and foams such as polystyrene must be checked in advance. If applied in the correct thin layer, the adhesion of subsequent coatings (e. g. plasters, paints) is not affected

What is MasterFinish RL 211 used for?

MasterFinish RL 520 is suitable for use on all conventional formwork types such as steel, wood, and resin-coated formwork. Rubber-lined, silicone or polyurethane moulds are generally compatible with MasterFinish RL 520. However, a compatibility test is strongly recommended since the type of elastomers for formwork is immense. The product has low drainage inclination with vertical formwork. It can be used in MCP, precast and in-situ concrete. When used for in-situ concrete construction, it must be ensured that the formwork panels are protected from weathering until the emulsion breaks

What are the benefits of MasterFinish RL 211?

MasterFinish RL 520 gives an improved exposed sur­face of concrete economically by reducing the application time, quicker stripping, easier and faster cleaning of the forms and increased life of the formworks.

It's safe and eliminates many health and environmental risks as compared to the traditional form release agents based on mineral oils and thus can be used with the maximum confidence by the workers on the job site and precast factory.
