XS-220 polyol is used to produce coatings, adhesives, sealants and elastomers.
XS-220 polyol is slightly hygroscopic and may absorb moisture, which would affect the properties of the products. The polyol should be stored in sealed containers and in dry conditions, away from direct sources of heat. Polyol is supplied in drums and tank trucks; or confer with supplier.
XS-220 polyol has a very low odor of acute toxicity and does not present a significant health hazard to users. Normal standards of industrial hygiene should however be observed when handling this chemical. Suitable protective clothing and eye protection must be worn to avoid unnecessary contacts and accidental ingestion. In case of eye contact, seek medical attention.
XS-220 polyol will burn under certain condition and can explode if heated to decomposition temperature in a confined area. Polyols fires can be extinguished with water fog, carbon dioxide or dry chemicals.
