International Chemical Safety Cards ETHYLENE GLYCOL DIMETHACRYLATE ICSC: 1270 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS LIQUID. PHYSICAL DANGERS: Vapours are uninhibited and may polymerize, blocking vents. CHEMICAL DANGERS: The substance may polymerize. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK: sensitization of skin (Sh); (DFG 2004). ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation and through the skin. INHALATION RISK: No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: The substance is irritating to the eyes and the respiratory tract . EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact may cause skin sensitization. PHYSICAL PROPERTIES Boiling point: 260°C Melting point: -40°C Relative density (water = 1): 1.05 Solubility in water: none Vapour pressure, Pa at 20°C: 478 Relative vapour density (air = 1): 6.8 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.03 Flash point: 101°C Octanol/water partition coefficient as log Pow: 1.87 ENVIRONMENTAL DATA N O T E S Environmental effects from the substance have not been investigated. Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken. An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert. Ageflex EGDM, Nourycryl M221, Sartomer SR 206 are trade names.
