Duramould

The only solution for concrete moulds available on the market. A two-component polyurethane system designed to ensure the flexibility and durability of forms along with hydrolysis resistance, as well as the convenience of processing concrete products. Duramould systems can be cold processed (at room temperature, i.e. 25ºC).

Quick processing guide – Duramould

Duramould – processing at room temperature:

1. Prepare the model: seal the model-box contact line and the box with silicone. Coat the model and the box in which it is placed with a separator.
2. Before use, polyol should be mixed at slow speed for about 5-10 minutes with a stirrer mounted in a drilling machine, then wait for about 30 minutes to bleed air from the material. Isocyanate does not require mixing.
3. Place an empty, clean and dry container on the scale; tare the scale.
4. Weigh out the polyol component. Add the isocyanate component.
5. Mix using a drilling machine with a tip that does not cause the aeration of the material. Mix at low speed.
6. Pour the mixture into a clean container, mix again for a few minutes. Bleed air from the material if necessary.
7. Calmly, pour the material into the model box. Pour a thin stream onto one point, do not pour from a height.
8. The mould should be removed after 24 hours, after which the mould should be aged on an even plate at room temperature for 48 hours.

General instructions for polyurethanes processing

Moulding silicone

The silicones available in our offer are two-component, liquid systems cured at room temperature. They are characterized by exceptional tear resistance and great working properties (exceptional anti-adhesive properties and easy unforming / demoulding. They are used, among others, as moulds for: resin, polyester, polyurethane, wax, parget, plaster of Paris, and concrete cast.

• MBSIL-P Silikon addycyjny
• MBSIL-T Silikon kondensacyjny

Instructions for silicones processing

1. Clean the surface of the material, if necessary (while using porous material) use a release agent: petroleum jelly, or aqueous soap solution.
2. Mix part A thoroughly before use.
3. In a clean container, weigh out equal amounts of components A and B. Mix them manually or mechanically (pay attention not to do so for too long, do not exceed the temperature of 35°C in the mixture).
4. Bleed air from the mixture if necessary.
5. Pour the mixture onto the original, leave to season for 24 hours at room temperature. Then remove the original from the mould.
6. The final mechanical parameters of the mould will be obtained after 7 days.
