What is BS EN 16074 - Paints and varnishes about?
BS EN 16074 is a European standard on paints and varnishes which helps in determining non-volatile-matter content and spreading rate of coil coating materials.
BS EN 16074 specifies the gravimetric procedure for determining the non-volatile-matter content as a percentage by mass of the majority of thermally cured coil coatings and subsequently for determining the theoretical spreading rate.
Note: The method is not suitable for pure epoxy coil coatings.
Who is BS EN 16074 - Paints and varnishes for?
BS EN 16074 on paints and varnishes is useful for:
- Paints and varnishes manufacturers
- Coil coating materials manufacturers
Why should you use BS EN 16074 - Paints and varnishes?
Paints known as varnishes contain a solid binder dissolved in a solvent and are dried out as a result of its evaporation. They are widely used as materials for covering surfaces for decorative and protective purposes. Varnishes also have the ability to quickly cure in a very wide temperature range.
Spreading rate is the surface area that can be covered by a given quantity of coating material to give a dried film of requisite thickness.
Non-volatile matter residue by mass obtained by evaporation under specified conditions.
The non-volatile-matter content determination is based on the mass of dry residue of a known quantity of wet paint cured in a pan or applied on a metal panel. The spreading rate is subsequently calculated using the liquid paint density and the density of the volatile part.
BS EN 16074 can help you in the calculation of non-volatile-matter content and spreading rate of coil coating materials, this will give you more information on your products and thus improve efficiency.
What’s changed since the last update?
BS EN 16074:2019 supersedes BS EN 16074:2011, which is withdrawn. BS EN 16074:2019 includes some technical changes with respect to BS EN 16074:2011. These are:
- The symbols have been aligned with current standards [ISO 3251 and ISO 3233 (all parts)], i.e. m for mass, s for spreading rate, NV for non-volatile matter and ρ for density
- Clause 8 on "Determination of the density" has been added
- The text has been editorially revised and the normative references have been updated
