IMPORTANT DATA
Physical State; Appearance
PALE YELLOW TO AMBER, FRAGMENTS OR POWDER, WITH CHARACTERISTIC ODOUR.

Chemical dangers
The substance decomposes on heating producing irritating fumes.

Occupational exposure limits
TLV: As rosin core solder thermal decomposition products (colophony). Exposure by all routes should be carefully controlled to levels as low as possible. SEN; (ACGIH 2004).
MAK: Sh; (DFG 2003).

Routes of exposure
The substance can be absorbed into the body by inhalation of fumes.

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered or as fumes.

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation exposure may cause asthma.
