DEMCO PUR 3000 PRC

Description

A two-component, flame-retardant polyurethane coating material with low toxic gas emission. It is used as a PRC coating and as an elastic intermediate coat.

Advantages

• Thanks to its elastic structure, it moves together with the surface it is applied to.
• Used on ‘floating floor’ surfaces on ships.
• Does not spread flame and has flame-retardant properties. Has a test report of compliance with the IMO Res. A.653 standard.
• After full cure, the amount of toxic gas released in the event of fire is below the limits. A test report confirming compliance with IMO Res. A.653 is available.
• Provides good waterproofing through seamless wall-to-wall application.
• Resistant to chemicals.
• Resistant to thermal shock.

Suitable Substrates

• Concrete surfaces (primed with DEMCO EPOX 100 PR).
• Metal surfaces (primed with DEMCO EPOX 132 PR/S).

Surface Preparation and Application

Surface Preparation:

• Surfaces to be coated must be free of oil, rust, dust and similar contaminants.
• If the surface to be coated is metal, it must be primed with DEMCO EPOX 132 PR/S.
• The concrete surface must be free of moisture, and no loose layer whatsoever may remain. Glossy surfaces must be roughened by shot blasting, grinding or milling.
• The prepared concrete surface must be primed with the Solvent-Free Epoxy Impregnating Primer DEMCO EPOX 100 PR, following the application instructions, so that it is fully impregnated.
• Any cracks and holes in the surface must be repaired using DEMCO EPOX 284.

Mixing:

• All of component B should be poured into component A, and the two components should be mixed at low speed for 3-5 minutes until a homogeneous mixture is obtained. The mixing time should be at least 3 minutes and should not exceed 5 minutes.
• Prepare a suitable quantity of mix during the work and continue working until all of the prepared mix has been used.

Application:

• At least 24 hours after primer application and once the surface is dry, the DEMCO PUR 3000 mixture is poured onto the primed surface and spread to a thickness of approximately 3 mm, preferably 5 mm, using a notched trowel or squeegee.
• To release air bubbles and ensure even spreading, the surface is rolled with a spiked roller, completing the application.
• Must not be diluted with thinner.

Application Conditions

• Working area temperature must be 15°C – 30°C.
• The ideal substrate temperature is 15°C – 30°C. The temperature must never be below 10°C.
• For indoor and outdoor applications, substrate temperature, ambient temperature and ambient humidity must be taken into account.
• Substrate moisture must be below 4% and ambient humidity below 65%.
• For 24 hours after application, the surface must not be touched and must not come into contact with water.
• When applied at 20-25°C, DEMCO PUR 3000 reaches full cure at room temperature in an average of 7 days.
• Viscosity may vary depending on substrate, ambient and material temperature.
• Application of DEMCO PUR 3000 and other floor coatings must be carried out by specialist applicators.

Coverage

A dry film thickness of 3-3,5 mm is obtained in a single application at a coverage of 5000 g/m².

Storage and Shelf Life

At 15-25°C, in dry, enclosed warehouses away from direct sunlight and in unopened original packaging: 24 months.
