Sherwin-Williams Magnalux 41VP is a two/three component vinyl ester based holding primer for use under all polyester and vinyl ester coatings.
It is overcoatable with other Magnalux products and is suitable for use on both blast cleaned steel and concrete surfaces (service temp above 85°C).
Magnalux products must not be applied over any existing painted surface, or any substrate which contains copper or zinc compounds. This includes sprayed surfaces.
Please note: This product is subject to a 14 day lead time upon ordering.

*This figure makes no allowance for surface profile, uneven application, overspray or losses in containers and equipment. Film thickness will vary depending on actual use and specification.
** All vinyl/polyester resin systems are subject to monomer loss and material shrinkage during application and curing.
Mixing Ratio:
Sherwin-Williams Magnalux 41VP is a two/three component material supplied in separate containers to be mixed prior to use (Retarder above 15°C required)
100 parts base to 2 parts catalyst by weight
Below 15°C, add catalyst to base component and mix thoroughly with a mechanical stirrer for at least 2 minutes
Above 15°C, add retarder (included) to base and mix thoroughly with a mechanical stirrer for at least 2 minutes
Allow a minimum of 3 minutes before adding catalyst, then stir for a further 2 minutes
*Maximum sag tolerance with overlap typically 50μm dry by airless spray

These figures are given as a guide only. Factors such as air movement and humidity must also be considered.
Application Equipment
Airless Spray:
Nozzle Size
0.38mm (15 thou)
Fan Angle
50°
Operating Pressure
196-220kg/cm² (2500-3150 psi)
Airless Spray:
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
Note:
Airless spray application should not be used for priming concrete
Use only brush or roller application for concrete substrates (preferably brush)
Brush:
The material is suitable for brush application
Application of more than one coat may be necessary to give equivalent dry film thickness to a single spray applied coat
Roller:
The material is suitable for roller application
Application of more than one coat may be necessary to give equivalent dry film thickness to a single spray applied coat
Surface Preparation
Blast clean to Sa2½ ISO 8501-1:2007. Minimum surface profile 75 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 15°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
Application at steel temperatures above 50°C is not recommended
If it is desired to overcoat outside the times stated on the data sheet, please seek advice of Sherwin-Williams
Additional Notes
Drying times, curing times and pot life should be considered as a guide only
Solids by volume of the product can vary significantly, depending on the amount of monomer lost and shrinkage during application and curing
Method of application and temperature/ventilation conditions will therefore affect the practical solids contents
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 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 sprayed surfaces
Numerical values quoted for physical data may vary slightly from batch to batch
