Questions about water-soluble phenolic resins
Thread Content
I have a question: How is the hazard associated with water-soluble phenolic resins defined? No information on the physical and chemical properties of such resins can be found online, so how can their fire hazard be determined?
Water-soluble phenolic resin does not refer to the resin obtained through polycondensation, but rather to one whose raw materials are mixed using water-soluble solutions. Generally, phenol is used in an alkaline solution, while aldehydes are used directly in an aqueous solution; upon mixing these two substances, a polycondensation reaction occurs to form an insoluble phenolic resin. The hazard of these materials can be determined with reference to substances such as phenol, formaldehyde, and alkalis.
Can it be defined in this way? During the polycondensation reaction, its properties change as a result :)
