Abstract
For industrial surface treatment the products are usually chosen on a basis of their technical properties. These products, however, can have serious consequences for the working environment and the external environment. The brochure that provides the basis for this case story contains a ranking system used for industrial surface treatment which takes the working environment and the external environment into account.

Description of Substitution
Products for industrial surface treatment are usually selected on the basis of their technical properties. These products, however, can have serious consequences for the working environment and the external environment. This leaflet aims to make it easier to choose systems that take into account the needs of the working environment and the external environment. The document contains a ranking systems used for industrial surface treatment. The ranking is illustrated by a staircase. The top level step refers to the alternatives of first priority concerning the work environment and/or the external environment. For working environment the document refers to a "code-number" which is a Danish system of ranking products in relation to occupational health standards. The code number consists of two numbers joined with a hyphen. The number before the hyphen represents the safety precautions to be taken against inhalation of vapours from the volatile substances. The number after the hyphen represents the safety precautions to be taken in relation to skin- and eye damage, spray mist or ingestion. A low code-numbers signifies a low risk for health and safety. For more information on code-numbers please see "Code-number" http://www.subsportplus.eu/substitution-tools/determination-and-work-with-code-numbered-products-mal-code SUBSPORTplus homepage. The following types of anticorrosive paints (or combinations) are ranked on five steps:
Step | System | Comments |
1 | Aqueous acrylic Zinc silicate | The load on the working environment is ranked as low and the load on the external environment is also ranked as low. Moreover the VOC (volatile organic content) is low. |
2 | Aqueous epoxy /aqueous acrylic | On the second step, the load on the working environment is ranked as low (MAL-code: low number before the stroke, high encoded after the stroke) and the load on the external environment is also ranked as low. Moreover the VOC (volatile organic content) is low. Some epoxy products may have so high molecular weight that they fall outside of the Danish epoxy legislation. This is yet undecided. If so, they can be ranged in step 1. |
3 | Epoxy solvent based/aqueous acrylic Aqueous epoxy /polyurethane | The load on the working environment can be ranked as low or high according to MAL-codes. The load on the external environment is also ranked as low or high with low or high VOC (volatile organic content). |
4 | Alkyd solvent based Chlorinate rubber Acrylic solvent based | The load on the working environment is ranked as high (MAL-code: high number before the stroke) and the load on the external environment is also ranked as high with a high VOC (volatile organic content). |
5 | Epoxy solvent based Epoxy/polyurethane Zinc ethylsilicate/epoxy Zinc ethylsilikat/epoxy/polyurethane | The load on the working environment is ranked as high (MAL-code: high number before the stroke, high encoded after the stroke) and the load on the external environment is also ranked as high with high VOC (volatile organic content). Heating can lead to the formation of unwanted connections. Heating of polyurethanes can e.g. result in formation of isocyanates. |
Case/substitution evaluation
This case concerns groups of substances and product types and not specific chemical substances. Therefore, the alternatives cannot be assessed according to the database of hazardous substances according to SUBSPORTplus screening criteria (SDSC). Users can screen individual examples of these substances using the SDSC and perform more detailed assessment of hazards.
