Conclusion on classification

Based on the results obtained and classification and labelling by the German Competent Authority for polyaldimine substances (e.g. EC # 479-940-2 and EC # 479-930-8), SIKA Hardener LH was not classified and labelled according to Regulation 1272/2008/EC (CLP).

The substance is not classified with regard to environmental toxicity, as the substance is readily biodegradable as shown in a testin accordance with "Method for Testing the Biodegradability of Chemical Substances by Microorganisms" stipulated in the "Testing Methods for New Chemical Substances" (March 31, 2011, No.0331-7, Pharmaceutical and Food Safety Bureau, Ministry of Health, Labour and Welfare; March 29, 2011, No.5, Manufacturing industries Bureau, Ministry of Economy, Trade and Industry; No. 110331009, Environmental Policy Bureau, Ministry of the Environment, Japan).
In addition all enviromental toxicity data from algae, fish and daphnia reveal EC50 and NOECs well above the threshold for classification of ready biodegradable substances of 1 mg/L.
