Kem-Kromik 530 (formerly known as Sherwin-Williams C530 or as Leighs C530) is a high quality, quick drying, lead free single pack alkyd gloss finish for interior and exterior surfaces, ideally suited for equipment manufacturers and for structural steelwork. Kem-Kromik 530 possesses excellent gloss and colour retention and outstanding durability, and can be applied by brush, roller, conventional and airless sprayers.
BS476 Part 7 - Surface Spread of Flame material - For details of substrate/scheme, consult our Technical Department.
Ensure surfaces to be coated are dry and free from all visible traces of surface contaminants.
Can be applied by brush and roller, as well as conventional and airless sprayers:
- Nozzle Size: 0.33mm (13 thou)
- Fan Angle: 65°
- Operating Pressure: 155kg/cm² (2200 psi)
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. If in doubt our technical team should be consulted.
- Nozzle Size: 1.27mm (50 thou)
- Atomising Pressure: 3.5kg/cm² (50 psi)
- Fluid Pressure: 0.7kg/cm² (10 psi)
The details of atomising pressure, fluid pressure and nozzle size are given as a guide. It may be found that slight variations of pressure will provide optimum atomisation in some circumstances according to the set up in use. Atomising air pressure depends on the air cap in use and the fl uid pressure depends on the length of line and direction of feed i.e. horizontal or vertical.
For application by conventional spray, thin up to 5% with Cleanser/Thinner No.1. Wet film thickness should be adjusted accordingly. NB - Thinning will affect VOC compliance.
Application Conditions & Overcoating
In conditions of high relative humidity, i.e. 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 times will be signifi cantly extended, and spraying characteristics may be impaired.
Application at ambient air temperatures below 5°C is not recommended.
This material is somewhat thixotropic to enable easy brush application. Any skin that may form on the surface of the paint in the container should be removed carefully to avoid the necessity of sieving the paint.
Numerical values quoted for physical data may vary slightly from batch to batch.
Certain shades for example, yellows, oranges and reds may require additional coats to achieve full opacity.
