Importance of Non-Volatile Matter Determination
The determination of the percentage volume of non-volatile matter is a critical factor in evaluating the performance of paints and varnishes. Non-volatile matter is the portion of the paint that remains after the volatile components have evaporated. This component is responsible for forming the film that provides the desired protective and aesthetic properties.
Understanding the non-volatile content helps manufacturers and users to:
- Ensure consistency in product quality.
- Optimize the formulation for specific applications.
- Predict the coverage and durability of the coating.
- Comply with environmental regulations by minimizing volatile organic compounds (VOCs).
Methodology
The BS EN ISO 3233-2:2019 standard employs a dual approach to determine the non-volatile matter content and the dry film density:
1. Non-Volatile Matter Content
This part of the method is conducted in accordance with ISO 3251, which involves heating a sample of the paint or varnish to a specified temperature to evaporate the volatile components. The remaining residue is weighed to calculate the percentage of non-volatile matter.
2. Dry Film Density
The dry film density is determined using the Archimedes principle. This involves submerging a coated test panel in a liquid and measuring the displacement to calculate the density of the dry film. This measurement is crucial for understanding the film's physical properties and its performance in real-world applications.
Applications and Benefits
The BS EN ISO 3233-2:2019 standard is widely used across various sectors of the coatings industry, including:
- Automotive: Ensuring high-quality finishes that withstand environmental stressors.
- Construction: Providing durable and aesthetically pleasing coatings for buildings and infrastructure.
- Marine: Offering protective coatings that resist corrosion and biofouling.
- Industrial: Delivering coatings that enhance the longevity and performance of machinery and equipment.
By adhering to this standard, companies can achieve several benefits:
- Improved product reliability and customer satisfaction.
- Enhanced reputation for quality and compliance.
- Reduced risk of product failure and associated costs.
- Increased competitiveness in the global market.
Conclusion
The BS EN ISO 3233-2:2019 standard is an indispensable tool for professionals in the paints and varnishes industry. By providing a clear and reliable method for determining the percentage volume of non-volatile matter, it helps ensure that coatings meet the highest standards of quality and performance. Whether you are a manufacturer, tester, or applicator, this standard will guide you in producing coatings that not only meet but exceed industry expectations.
Invest in the BS EN ISO 3233-2:2019 standard to enhance your understanding and application of non-volatile matter determination, and take your coatings to the next level of excellence.

This standard BS EN ISO 3233-2:2019 Paints and varnishes. Determination of the percentage volume of non-volatile matter is classified in these ICS categories:
- 87.040 Paints and varnishes
This document specifies a method for determining the non-volatile matter by volume (NVV) of coating materials by determining the practical dry-film density. This method determines the volume percentage of non-volatile matter in paints, varnishes and related products by measuring the density of a dry coating for any specified temperature range and period of drying or curing. The non-volatile matter content is determined in accordance with ISO 3251.
Using the non-volatile matter by volume results obtained in accordance with this document, it is possible to calculate the practical spreading rate of coating materials.
This method specifies an additional shape of plate to those described in ISOÂ 3233-1 and is suitable for all products which can be applied by dipping.
This document is not applicable to coating materials which exceed the Critical Pigment Volume Concentration (CPVC).
Annex A gives an overview of the existing methods for the determination of non-volatile matter content and of non-volatile matter volume.
