PRODUCT DESCRIPTION
It is a two-component, pure polyurea system. It is 100% solvent free, 100% solid. The aromatic product does not create joints and joint fillings. It takes the shape of the surface.
SCOPE OF APPLICATION
The application area of DUAYEN SPREY MS 955 System is very wide due to its superior characteristics.
Its application area is very wide due to its extremely superior characteristics. It can be applied in many areas from the construction industry to the aviation industry. Provides superior anticorrosion protection on all metal and steel constructions (bridges, tunnels, pools and pipelines). Apart from anti-corrosion protection, it can also be used as an industrial floor covering exposed to heavy conditions. Applicable surfaces: concrete, steel, wood, metal and all other construction materials.
Typical applications:
•In metal and steel constructions
• Bridges and Tunnels
• Refineries
•Heating pipelines, oil pipelines, gas pipelines
•In the ship industry
• Coating of truck cases and freight wagons
Industrial floors that require a highly durable coating
FEATURES
• It contains all the features of hydroinsulation, anticorrosion and topcoat paint.
• Quickly applied (one worker / 1 hour / 250 m²/ thickness 2 mm)
• 1.5-2 mm thick layer provides maximum hydro-isolation
•Hardening time is 10 seconds
•The surface is compact regardless of how many layers are applied.
• It is very resistant to abrasion, has no joints and covers cracks
• Excellent chemical resistance
• No need for layered application
•Applicable to all construction materials
• Application temperature range is very wide (0- 45°C)
• It has excellent thermal shock resistance (-40°C- +200°C) 35 seconds after the application, it is possible to walk on the ground.
• Vehicles can rise on the floor 1 hour after the application.
•It is ecological
•Long life (estimated 25 and above)
APPLICATION
The material to be applied must be clean and dry, free from dust, oil and other contaminants. For the desired level of adhesion, suitable primers can be used to improve long-term adhesion stability and adhesion to metal surfaces. The surface of plastic materials should be cleaned, mold release agents that may be found on the surface should be removed. Abrading and sanding the surface can increase adhesion.
•Application method: 2 coats, without waiting.
•Smooth floor ensures less consumption. There should be no large patches or protrusions on the surface. When smoothing rough floor and wall surfaces, care should be taken to ensure that the pores are as few as possible in order to prevent bubbles from forming on the surface, and the surface should be free of substances such as rust, dust and oil. After the smoothing process, Duayen Primer suitable for the floor should be used.
•Concrete surfaces must be mechanically compact/sturdy and resistant to 1.4 MPa flexural-tensile forces.
• Duayen Spray can be applied to the newly poured concrete after 28 days.
• Moisture rate in the concrete must be controlled. Maximum humidity can be 4%.
• If the surface is new and weather conditions are suitable, Duayen Spray can be applied directly without applying a primer.
• It is important for a safe application that the floor temperature where the application will be made is 3°C above the dew point temperature of the air.
• If the air temperature is below +8°C, Duayen Epoxy primer must be applied.
• Application cannot be made if the surface is covered with ice.
•Spray application may be very soft or hard at the beginning depending on the floor temperature. The product starts to gain strength after 1-2 hours and reaches 95% strength values after one day. After a week, it reaches its full values.
• If the concrete requires a vapor membrane, it must be applied before Duayen Spray.
•Steel surfaces must be sandblasted. ISO 8501-1, smoothness grade R≤130 170μm.
• It is obligatory to sandblast the tile surfaces. After sandblasting, a thin Duayen Epoxy primer should be applied and then Duayen Spray should be applied.
