Perma MRA

SOLVENT BASED CHEMICAL MOULD RELEASING AGENT
DESCRIPTION

Perma MRA is a chemical release agent suitable for shutters and moulds. Clean release gives a fair faced concrete surface.

Perma MRA
PRIMARY USES

Perma MRA is suitable for all types of shutters and moulds. Perma MRA can be applied to steel, timber, plywood, plastic and rubber moulds.

ADVANTAGES

Perma MRA gives very good shutter releasing properties. Other oils used in similar application penetrate into the concrete and interfere with the strength of the member. Apart from this they leave ugly stains on the concrete surface. Before subsequent finishes one needs to chemically or mechanically remove these stains and leftovers of these oils. Perma MRA is designed keeping all these problems in mind and to ensure least damages to the shutters and to the concrete. Application of conventional mould releasing oils is tedious and time consuming. Perma MRA can be sprayed saving time and labour.

DIRECTIONS FOR USE

When using for the first time spray Perma MRA on the shutters while erecting them and just before concreting. Thereafter Perma MRA can be sprayed just after deshuttering and cleaning. During initial uses new commercial ply shutters tend to be absorptive. Hence it is necessary that new ply shutters are sprayed just before concreting also.

ACTION

Perma MRA reacts chemically with cement in such a manner that excellent release properties are imparted to the treated face of the shutters and moulds. Concrete casted with Perma MRA on the shutters have smooth, hard uniform and light coloured finish. The adhesion of subsequent finishes such as renders, paints or textured coating is unaffected by use of Perma MRA.

PROPERTIES

Specific gravity : 0.85 at 20°C
Chloride : Nil
Sulphates : Nil
Nitrates : Nil
Freezing Point : minus 10°C
Flash Point : 60°C

COMPOSITION

Low viscosity hydrocarbon vehicle blended with chemically active release agent.

COVERAGE

Perma MRA covers 25 to 50 m2/litre when spray applied. On new steel shutters the coverage is about 50 m2/litre. In case of plywood as well as metal shutters better coverage results are obtained by progressive use of Perma MRA. When brush applied less coverage is obtained because of evaporation losses.

PACKING

Perma MRA is available in 20 Litres and 200 Litres drum.

SHELF LIFE

Perma MRA has a shelf life of 24 months from the date of manufacture.
