Abstract

Seven paint strippers were tested on the keel of a sailing boat. The test showed, that a stripper based on vegetable oil could be used instead of strippers containing classified solvents such as xylene, N-methyl-2-pyrolidon or 1,3-dioxolan.

Hazard Assessment

Substances to be substituted: According to the MSDSthe two strippers that can be substituted with the alternative contain: This product contains 1,3 dioxolane, dimethoxymethane, propane-2-ol, naphtha and methanol as active substances. 1,3 dioxolane is not listed in the SUBSPORTplus Database. Dimethoxymethane is not listed in the SUBSPORTplus Database and has no harmonised classification according to Annex VI of Regulation (EC) No 1272/2008 (CLP Regulation). Propan-2-ol is not listed in the SUBSPORTplus Database. Naphtha, light aromatic is not listed in the SUBSPORTplus Database. Methanol 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). The product contains butanone, n-butyl acetate, orange terpenes, C10 alcohol ethoxylate. Butanone is not listed in the SUBSPORTplus Database. n-Butyl acetate is not listed in the SUBSPORTplus Database. Alternative substances: The alternative product is based on vegetable oils, synthetic esters that are not classified ingredients. The alternative also contains: 1-ethylpyrolidine-2-one 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).

Description of Substitution

The Danish magazine Båd-nyt (Boat-news) performed in 2011 a test of seven different paint removers to strip the paint from the keel of a sailing boat. Different kinds of antifouling paints are used on smaller sailing boats. The keel is painted every year and all the paints have in common, that after a period of years they start to peel or you have to strip all the layers to keep the antifouling effect. In earlier days this was efficiently done with products containing trichloroethylene, but this is not allowed nowadays because of the hazardous properties of the substance. This is the background why the magazine wanted to test some of the products available on the market now. All the tests were performed on the same keel by applying the paint stripper with a paint roller. The viscosity of the stripper has to be high, to keep it from running down the keel. Under the application the worker wore protective gloves of a three layer laminate material (4H- glove). The effect of the strippers was compared after 15 min., 60 min. and after coverage with a plastic film for 24 hours. The stripping was performed by scraping and the residues were collected on a piece of plastic placed under the boat. A high pressure water cleaner was not used, because it is not allowed to discharge the waste water to the sewer system or on the soil. Three paint strippers performed good after 24 hours. The stripper based on vegetable oil was the most environmentally friendly product. It costs around 100% more per square meter than the other compounds.

Case/substitution evaluation

The paintstripper based on vegetable oil is a less hazardous alternative to strippers containing classified solvents such as butanone, N-butyl acetate or 1,3-dioxolan. Also the vapour pressure is much lower. This gives a lower risk of inhaling vapours of the product.
