Technical Data | ||
---|---|---|
Finish | Semi-Gloss | |
Pack Size | 20L | |
Flash Point | 28°C | |
Colour | Off White or Light Grey | |
Pot Life | 50 minutes at 20°C | |
Theoretical Spreading Rate | 1.8m²/litre at 500 microns | |
Solids By Volume | Theoretical 98% at time of mixing. Practical typically 90% ± 5%* | |
VOC | <50 gms/litre determined practically in accordance with UK Regulations PG6/23 |
*All vinyl / polyester resin systems are subject to monomer loss and material shrinkage during application and curing.
Mixing Ratio:
- 98:2 base to hardener
- Retarder (included) must be added when application temperature exceeds 15°C
Shelf Life:
- Base and 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
Recommended Thickness
Between 500 and 3000 microns dependent upon duty and environment. This material is a barrier coating and the thickness needed is dependent upon service conditions.

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

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:
- For temperatures upto 85°C use Magnalux 42PP, for temperatures above 85°C use Magnalux 41VP
Overcoating:
- Overcoatable with itself or Magnalux 43VC
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 48 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 25°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 41PV
- 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 41V2 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
