The very complex issue of the release of volatile organic compounds (VOCs) into the environment is also the subject of research and development regarding intumescent paints.
In fact, intumescent paints and varnishes are generally applied in much thicker layers compared to traditional decorative paints. The contained and released quantity of VOC can therefore be much higher.
Not to underestimate the fact that the intumescent film applied to the support releases VOC over time. The point of attention considering VOC emission is focused on the health of the internal environment and its future occupants.
Emission tests are carried out with special equipment in a closed test chamber. The presence of solvents that are potentially released by the product – which is applied in the average thicknesses used on site – are detected via instrumental analysis.
We can distinguish two different types of tests concerning the VOCs:
- VOC Content – Verification and certification of the volatile organic substances contained in the product
- VOC Emission – Verification and certification of the amount of VOCs released into the environment by the protective system applied and hardened after 28 days
This is the reason why Amonn has decided to test its intumescent products according to the Indoor Air Comfort (Gold).
