Toxicity and Protection
This product is toxic and has strong irritation to eyes, skin and mucous membranes. Operators should wear protective equipment.
store
HDI must be stored in an airtight container to prevent other impurities and water vapor contamination, which will negatively affect the processing properties of the product; the recommended storage temperature is -34°C to 50°C, and it is stable at 25°C in an airtight original container. Store for one year.
