Hybrid polyurea is a two-component, fast curing coating material used in waterproofing and flooring. This material, obtained by mixing polyurethane and polyurea resins, is more economical than pure polyurea. Hybrid polyurea, which is an environmentally friendly option thanks to its solvent-free structure, can adapt to the movements on the surface thanks to its crack bridging feature. Thanks to its fast curing feature, it shortens the application time and can be applied in all weather conditions. It is used in terrace insulations, water tanks, swimming pools, parking lots and industrial floors. Thanks to its high adhesion strength and long life, it provides trouble-free waterproofing for many years.
Hybrid Polyurea POLIUREA HB
POLIUREA HB is a hybrid polyurea based, two-component, solvent-free, waterproofing membrane that can be applied only by machine under all weather conditions as it cures very fast.
Advantages
- Cures very fast.
- Solvent free.
- Creates high crack bridging.
- Excellent adhesion even on difficult surfaces.
- It can be applied by machine and opened to traffic within minutes due to its fast curing.
- Maintains high elasticity even at low temperatures.
- Since it is applied in one piece and due to its high flexibility, it allows a seamless application and enables a jointless coating.
- It has excellent adhesion strength, chemical resistance and mechanical strength.
- Good resistance to many chemicals.
- Water vapor is permeable.
- Resistant to hydrolysis.
Application Areas
- Used on trapezoidal and sandwich panel roofs.
- Rooftop, terrace and terrace gardens,
- Foundation and curtain waterproofing,
- On reinforced concrete and sheet metal,
- Tunnels
- In waste collection tanks,
- Insulation and coating of parking lots,
- In water channels,
- Pools and similar water tanks,
- Waterproofing over parking lots,
- Waterproofing of green roofs,
- Protection of metals against corrosion,
Application Features
Surface Preparations:
Application surfaces must be dry, clean, bearing and solid. Dust, oil, grease, grease, paint and any similar dirt that may reduce adherence must be completely removed before application. Surface temperature should be min. +10 °C. Application surfaces should be free of defects such as pits, fractures, pores, segregation and cracks, should not be loose and should not be dusty. Such defects should be corrected with DFR 2000 TIX before application. Where necessary, surface preparation should be carried out by shot blasting, milling, sanding or similar mechanical surface abrasion processes and all surfaces should be cleaned of dust with industrial vacuum tools. Under all conditions, surface adherence must be above 1.5 N/mm² and moisture content must be below 4%. During application, it must be ensured that the ground temperature is at least +30 °C above the specified dew point.
Priming
- For absorbent surfaces: Dryfix DF PUR PRIMER 1K, Dryfix DF PUR PRIMER 2K
- For hard and normal floors: Dryfix DFC 100
Mixture Preparation
Preparation of Components:
Before starting the application, component B (amine resin) should be mixed in the barrel for at least 30 minutes until a homogeneous color is obtained. Mixing should continue during application. It is important that the temperature of A and B components should be between 65-75°C before application. The components should not be diluted in any way.
Spray Machine Settings:
Polyurea is applied to floors with a spraying machine operating at high pressure and temperature. Machine settings should be checked continuously during application.
- Component A (MDI Prepolymer) Temperature: 70-71 °C
- B Component (Amine Resin) Temperature: 67-68 °C
- Hose Temperature: 67-68 °C
- Machine Pressure 140-180 bar
After all preparations are completed, the polyurea is sprayed on the surface in 2 coats to obtain a minimum thickness of 2 mm. The application thickness should be checked regularly by cutting sample pieces from the floor or applying sample plates and measuring the thickness and the minimum thickness should be reached at every point. Thin sections or repairs should be made within 5 hours after application.
Completed surfaces should be protected from mechanical stress for at least 24 hours. Fresh surfaces should be protected from water, dew and similar external factors and accumulations on the surface should be avoided. The dew point should be checked before application, and the mixture ratio should be constantly checked whether the mixture is at the original balance by looking at the machine pressure hours.
