    *All vinyl / polyester resin systems are subject to monomer loss and material shrinkage during application and curing.

    Mixing Ratio:

    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
    Dry500* Microns Per Coat (Mils)
    Wet555 Microns Per Coat (Mils)

    * Maximum sag tolerance typically 1110μm wet (1000μm dry) by airless spray



    Average Drying Times


    • Touch Dry - 6 hours @ 20°C
    • Service time / Full cure - 3 to 4 days @ 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 Size0.7 - 1.2mm (28-48 thou)
    Fan Angle45° - 60°
    Operating Pressure190-220kg/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
    • For optimum immersion service normal full cure must be achieved, ie 72 hours at 20°C (post curing at 80-100°C will shorten the cure time to 3 hours and may be recommended for some aggressive environments)
    • For immersion spark test at 5kv per 1.0mm dft and repair defects by overcoating with the specified dft of Magnalux 42SF
    • 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 42SF 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
