Choose raw materials responsibly
The raw materials, in the form of certain chemical components that are incorporated into paints and coatings, represent an exceptionally diverse list. Coating raw materials can be grouped into four categories of chemical components: resins, pigments, solvents and additives (additives include rheology modifiers; surfactants; dispersants; biocides; coalescents; catalysts; defoamers; adhesion promoters; as well as host of other specialized chemical constituents, which are typically used). These components constitute very low levels in the product, as a percentage of the formula weight.
With regard to the development of the formulation, it is necessary to look at the raw material use, the raw material cost distribution, and the CO2 emissions caused by the raw materials.
Sustainable selection of raw materials is possible, if they are evaluated and selected according to the following criteria:
- Environmental impact (Life Cycle Assessment);
- Material health (identification of hazardous ingredients);
- Availability (supply chains);
- Raw material price.
How do the ecolabels in Europe and the practice of Green Public Procurement (GPP) regulate choice of paint and coating products?
This analysis is designed to provide a simple overview of the ecolabels in Europe and Green Public Procurement (GPP) requirements towards raw material requirements.
