R-2588 PART A

SECTION 2: Hazards identification

EFFECTS OF SINGLE OVEREXPOSURE: SWALLOWING: Small amounts transferred to the mouth by fingers during use, etc., should not injure. Swallowing large amounts may cause digestive discomfort. SKIN ABSORPTION: No evidence of adverse effects from available information. INHALATION: Short-term harmful health effects are not expected from vapor generated at ambient temperature. SKIN CONTACT: May cause slight irritation and reddening. EYE CONTACT: May cause eye irritation, seen as excess reddening and swelling. EFFECTS OF REPEATED OVEREXPOSURE: Crystalline silica as respirable dust may cause silicosis. However, since the silica and iron oxide in this product are compounded into the polymer matrix, they are not expected to present the same hazards as their neat forms.

Medical Conditions Generally Aggravated by Exposure

OVEREXPOSURE A knowledge of the available toxicology information and of the physical and chemical properties of the material suggests that overexposure is unlikely to aggravate existing medical conditions. SIGNIFICANT LABORATORY DATA WITH POSSIBLE RELEVANCE TO HUMAN HEALTH HAZARD EVALUATION: Contains crystalline silica which is classified by IARC as an animal carcinogen and a probable human carcinogen. The EPA has expressed concern regarding the possible adverse health effects resulting from the inhalation of alkoxysilanes and has recommended that administrative and mechanical means be used to minimize exposures. OTHER EFFECTS OF OVEREXPOSURE: None currently known.
