Side A is an emulsifiable diphenylmethane diisocyanate (MDI), and proper care should be taken when handling this product. This includes protective clothing, gloves, eye shields, and respiratory protection. As with all isocyanates, proper breathing equipment should be used, and for optimum protection, a positive fed fresh-air mask should be used.

Side B is an oil-based polyol and also requires protective clothing to avoid exposure to the skin and eyes.
