Description of key information

The test method for the determination of the water solubility of a substance as described for liquid materials in Test Guideline A.6 of EC Regulation 440/2008 was replaced by a theoretical based evaluation. Due to the immediate hydrolysis of Sika Hardener LG upon contact with water, water solubility measurement was technically not feasible. For details on hydrolysis, please refer to the information given in IUCLID section 5.1.2.
Instead, the water solubility of Sika Hardener LG was calculated using the US EPI Suite (v4.0). The calculated water solubility of Sika Hardener LG was 0.2231 mg/L at 25°C and a pH range of 7.55-7.72. Thus, Sika Hardener LG was considered poorly soluble.
