SELEMIX® Frequently Asked Questions

How can I prevent paint damage to my product?

  1. Use a paint system suitable for the environment that it is going to be in – Consult the Selemix ISO12944 guide

  2. Consult the guide to cleaning and maintenance of paint films (attached)

What is the best way to apply a coating e.g. spray or brush?

Spraying will give the smoothest and most even finish.

Conventional (low pressure) spray will normally give the best finish.

High pressure spray (airless and air-assisted airless) will normally give a faster and more efficient painting process, especially for higher builds, but the finish will not normally be as good.

Can I recycle spray cans?

This is not normally possible, however contact your local authority or waste contractor to confirm.

Can I use the same equipment to apply both oil- and water-based paints?

Most waterborne paints can be applied through conventional and air-assisted airless spray equipment. Consult the product datasheets which will have full details. The recommended fluid tip sizes and pressures may be different from what you normally use.

Make sure that the equipment is fully cleaned out if changing between solventborne and waterborne products.

How can you prevent problems, such as rust?

What does VOCs stand for?

Volatile Organic Compound. This term is used to refer to organic solvents found in paints which are volatile (i.e. evaporate during the paint drying process).

Water is not classed as a VOC.

RoHS – How does this impact my business?

RoHS stands for Restriction of Hazardous Substances. It deals with restricting the use of certain hazardous materials in electrical and electronic equipment.

Please contact PPG’s technical department if you are affected by this and require more information.

UK Rules and Regulations

Paints supplied for refinishing of road vehicles, must comply with Paint Products Directive Legislation. This restricts the VOC content of individual paint products, and paints with a higher VOC content cannot be used.  

See Process Guidance notes PG6/34. Please note that mobile machinery, construction equipment, and agricultural equipment are not classed as road vehicles, and come under industrial painting

Industrial painting come under different legislation which does not control the VOCs of individual paint products, but controls the total VOC emissions to a percentage of the total paint solids use

This varies according to emission level, but can be summarised thus:

Annual VOC emissions under 5 Tonnes – Not regulated (Note that local authorities can enforce further restrictions)

Annual VOC emissions 5-15 Tonnes – Total VOC emission must be less than 0.6 of paint solids

Annual VOC emissions 5-15 Tonnes – Total VOC emission must be less than 0.37 of paint solids

See Process Guidance notes PG6/23
