Concrete Admixture – Concrete Mould Release Agents-Oil Based （MNC-T6）

 

Oil Based Concrete Mould Release Agent

(MNC-T6)

 

Product Description

MNC-T6 is a specially formulated blend of mineral oils with a chemically active release agent that is suitable for application to mould and shutter faces prior to casting concrete in order to obtain a clean release. The alkali reactive chemicals promote a water-repellent interface which protects both steel and timber formwork whilst ensuring the resultant concrete has a smooth, hard, uniform finish with reduced incidence of blowholes.

MNC-T6 will also allow air to escape from the interface during placing and vibration thereby resulting in a reduction of remedial costs. Use of MNC-T6 has no negative effect on the quality of the concrete nor will it impair the adhesion of subsequent coatings providing application is made at recommended coverage rates.

When applied at recommended coverage rates MNC-T6 is non toxic and may be used in for concrete in potable water applications.

Uses

• For quick, clean and easy stripping of moulds and formwork.
• For high quality, fair-faced and stain-free concrete.

Instructions for Use

Preparation: New moulds, if extensive reuse is anticipated, treat new moulds with a polyurethane coating. For used moulds, remove all traces of adherent material i.e. concrete, oil etc. The use of an acid etch will assist in the cleaning process.

Application:

1. Mix MNC-T6 with water before using. The amount of water added varies with temperature. When the temperature is high, more water may be added. You may add as much as six times of water in MNC-T6.

2. Clean the form surfaces and wait till they are dried before applying MNC-T6.
3. Spray or paint a thin coating of MNC-T6 onto the casting surface of all forming before each pour or cast of concrete. Hose clean and spray with MNC-T6 at the end of work. For hand tools, buckets, etc. simply soak in the container of MNC-T6 and allow drying.

Coverage

Depending on the porosity and texture of the mould surface, typical coverage rates of 30 to 60 m2/litre/coat may be obtained.

Packaging &Storage

MUHU Release Agent is available in 50 litre and 210 litre drums and it has a minimum shelf life of 12 months provided it is stored under cover, out of direct sunlight.
