Shelf Life:

  • Base: 12 months
  • Catalyst (Hardener): 6 months, stored at temperatures below 20°C, away from heat sources and out of direct sunlight
  • Frequent temperature cycling will shorten storage life

Practical Application Rates


Airless Spray
Dry 600* Microns Per Coat
Wet 666 Microns Per Coat

* Maximum sag tolerance typically 1111μm wet (1000μm dry) by airless spray



Average Drying Times


  • Touch Dry - 5 hours @ 20°C
  • Full cure - 7 days @ 20°C
  • Min. Overcoating - 5 hours @ 20°C
  • Max. Overcoating - 72 hours @ 20°C

These figures are given as a guide only. Factors such as air movement and humidity must also be considered.



Application Equipment


Airless Spray: Graco King 45:1 or similar - all filters removed - Min 3/8” hose diameter.

Airless Spray:
Nozzle Size 0.7 - 1.2mm (28-48 thou)
Fan Angle 45° - 60°
Operating Pressure 190-220kg/cm² (2700-3150 psi)



Notes:

  • The airless spray details given above are intended as a guide only
  • Details such as fluid hose length and diameter, paint temperature and job shape and size all have an effect on the spray tip and operating pressure chosen
  • However, the operating pressure should be the lowest possible consistent with satisfactory atomisation
  • As conditions will vary from job to job, it is the applicators' responsibility to ensure that the equipment in use has been set up to give the best results
  • Brush application is not recommended



Recommended Systems


Primer:

Overcoating:



Surface Preparation


  • Blast clean to Sa2½ ISO 8501-1:2007. Surface profile in the range 75-125 microns
  • Ensure surfaces to be coated are clean, dry and free from all surface contamination



Application Conditions & Overcoating


  • In conditions of high relative humidity, ie 80-85% good ventilation conditions are essential
  • Substrate temperature shall be at least 3°C above the dew point and always above 0°C
  • At application temperatures below 10°C, drying and curing times will be significantly extended, and spraying characteristics may be impaired
  • If application and curing temperatures fall below 5°C, full cure may not be obtained - post curing may be required for certain aggressive environments - see additional notes
  • It is not advisable to apply polyester coatings when the air or substrate temperature exceeds 45°C, or the substrate temperature exceeds 55°C
  • These conditions can introduce paint film formation defects such as dry spray, pinholing, bubbling etc
  • For application outside these temperature limits it is recommended that advice is sought from Sherwin-Williams

Overcoating:

  • It is important to observe maximum overcoating times and note these will vary substantially with climatic conditions
  • Minimum, as soon as gel has occurred and whilst still tacky
  • Maximum at 20°C is 72 hours
  • Strong ultra-violet/sunlight will substantially reduce overcoating time
  • Once maximum overcoating time has been reached, adhesion values attained by any subsequent coat will reduce dramatically
  • Should this occur overcoating should be treated as a repair, with the coating flash blasted to provide a physical key
  • Styrene cannot be used to reactivate the surface of this product and may impair adhesion
  • Take care to avoid contamination before application of subsequent coats
  • Ensure ventilation during cure



Additional Notes


  • Drying times, curing times and pot life should be considered as a guide only
  • Consult Sherwin-Williams Technical Support for immersion times
  • For immersion spark test at 5kv per 1.0mm dft and repair defects by overcoating with the specified dft of Magnalux 42PE
  • The reaction between the base component and catalyst is highly exothermic
  • Deviation from the recommended mixing ratio should not be undertaken without first consulting Sherwin-Williams
  • The catalyst must be stored separately from the base, and from any other paint or chemical products, in accordance with the product safety data sheet
  • The quoted pot lives are typical figures for a full 20 litre unit @ 2% catalyst level
  • Should any thickening or lumps appear in the mixed product, this should be discarded and the equipment flushed through and cleaned immediately
  • Reduction in catalyst level and/or volume of mixed product will extend the pot life
  • Flushing of spray equipment is essential before any break in work, and is recommended at regular intervals throughout the application procedure
  • Only mix units of Magnalux 42PE as they are required for immediate use
  • Magnalux products should not be thinned with cleanser thinners or any other solvent
  • Thinning will severely impair the curing mechanism and subsequent performance
  • Thinning with normal paint solvent can lead to exothermic reaction and possible fire or explosion hazard
  • Magnalux products must not be applied over any existing painted surface, or any substrate which contains copper or zinc compounds
  • This includes copper or zinc based paints, or metal sprayed surfaces
  • Numerical values quoted for physical data may vary slightly from batch to batch
