    is a pre-blended rigid polyurethane spray polyol designed for the insulation of roof, wall and floor. 
    When
    reacted with ASMACO PUF MDI under the recommended reaction conditions, the foam has a good surface finish with excellent
    cell structure and good adhesion to various substrates.

    Polyol Component: mixture of base polyols, stabilizers, fire retardants, catalysts and blowing agent etc.
    Isocyanate Component: polymeric diphenylmethane diisocyanate.

    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
