CAS 39927-08-7 — Polyethylene glycol 600 diacid

Polyethylene glycol 600 diacid is a versatile diacid-terminated polymer used primarily in adhesives, coatings, and polymer synthesis to modify properties like flexibility, adhesion, and curing behavior. It serves as a reactive diluent, coupling agent, and chain extender in polyurethane and epoxy systems. This colorless to pale yellow liquid has a molecular weight of approximately 600 g/mol, a melting point of 38–42°C, and is soluble in water and many organic solvents. It is non-hazardous with no signal word classification, offering low toxicity and environmental friendliness. Molekula supplies Polyethylene glycol 600 diacid from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
