Abstract

Alternative polyurethane coatings can be identified by applying GISBAU (German hazardous substances information system for the construction sector). This example covers the replacement of product containing two carcinogens, sensitizer and reprotoxic, by safer and more environmental-friendly alternative.

Hazard Assessment

Substances to be substituted: Ingredients of the substituted product Sikafloor®-350 N Elastic have many hazardous properties which may cause cancer and sensitization by skin contact, may cause neonatal damage. 6-methyl-2,4-bis(methylthio)phenylen-1,3-diamine may cause an allergic skin reaction, according to Annex VI of Regulation (EC) No 1272/2008 (CLP Regulation). It fulfils the criteria to be listed in the Substance Database according to SUBSPORTplus Screening Criteria (SDSC). Naphtha, light aromatic may cause cancer cat. 1B, according to Annex VI of Regulation (EC) No 1272/2008 (CLP Regulation). It fulfils the criteria to be listed in the Substance Database according to SUBSPORTplus Screening Criteria (SDSC). 1-methyl-2-pyrrolidone is a Substance of very high concern and is included on the REACH restriction list, according to Article 73 of Regulation (EG) No. 1907/2006. (REACH Regulation). Tris(2-ethylhexyl) phosphate is not listed in the SUBSPORTplus Database and has no harmonised classification according to Annex VI of Regulation (EC) No 1272/2008 (CLP Regulation). M-tolylidene diisocyanate is a Substance of very high concern and is included on the REACH restriction list, according to Article 73 of Regulation (EG) No. 1907/2006. (REACH Regulation). Alternative substance: The ingredient of alternative Sikafloor®-375, Diphenylmethane diisocyanate, isomers and homologues have no harmonised classification and is not listed on the SDSC.

Description of Substitution

Most large producers of polyurethane coatings offer varieties of products. GISBAU – hazardous substances information system of the German statutory accident insurance for the construction industry (BG BAU) offers advice on how to choose the safest products from a chemical hazard point of view. You can find a short description of GISBAU here on pages 83-88. Products, which are the subject of this example, belong to the group of polyurethane (PU) systems. According to GISBAU they can be categorised into eight hazard classes (product codes): PU10 - PU systems, solvent-free PU20 - PU systems, containing solvents PU30 - PU systems, containing solvents, harmful PU40 - PU systems, solvent-free, harmful, sensitizing PU50 - PU systems, containing solvents, harmful, sensitizing PU60 - PU systems, reaction component based on amine, harmful, sensitizing PU70 - PU installation foams PU80 - PU installation foams, extremely flammable Manufacturers of construction chemicals voluntarily label their products according to the GISBAU coding system. Criteria for product groups and codes are agreed by employers, unions and producers. Using the product codes it is possible to find alternatives e.g. for a product labelled with PU60, which contains the hazardous substances listed above. A possible alternative product, containing alternative substance, labelled with product code PU40 is solvent-free. It does not require classification. The alternative is a two components, solvent free, low viscosity, tough elastic, crack-bridging polyurethane resin and can be used for:

• crack bridging, trafficable, slip resistant wearing layers
• car park decks, garage floors and bridges

Case/substitution evaluation

A reduction of health and environmental risks can be achieved using the alternative product. The polyurethane coating for drivable and slip resistant surfaces containing carcinogens, sensitizer and reprotoxic can be substituted with a safer and more environmental-friendly alternative.
