HANDLING PRECAUTIONS
When exposed to moisture, SCA-903 Silane hydrolyses, generating methanol. Appropriate measures should be taken to prevent the accumulation of hazardous concentrations of methanol fumes in the working environment. SCA-903 Silane causes severe irritation to eyes and irritation to skin. In case of contact, immediately flush with large amounts of water and obtain prompt medical attention. When handling SCA-903 Silane wear goggles or face shield and impervious gloves. Product safety information required for safe use is not included. Before handling, read product and safety data sheets, physical and health hazard information.
SHELF LIFE AND STORAGE：
