Asmaco PUF 40 Pre-Blended Spray Polyol

In general, the following should be taken into consideration:

• The system must be applied using plural-component spray equipment.
• Component Temperature: 300C ― 50 0C depending on weather condition.
• Component Pressure: 80 Bars ― 120 Bars.
• Ambient Temperature: +10 0C ― +50 0C
• Substrate Temperature: +10 0C ― +50 0C
• Relative Humidity: <50 %
• Wind speed: <20 km/h
• The substrate must be clean, free from oil, dust, and moisture.
• Pass thickness should not exceed 20 mm to maintain the designed density and dimensional stability.
• Thick passes cause a decrease in density and reduce dimensional stability of the foam.
• Very thin passes will increase the foam density and decrease product yield.
• There must be a time gap of 5 ― 10 minutes before applying second layer.
• Longer time gap is necessary for thicknesses above 100 mm.
• Coverage and in-place density is dependent upon the temperature of the substrate, ambient air temperature, pass
  thickness, spray gun parameters etc
