Used as a crosslinking agent in polymer chemistry, particularly in the synthesis of polyurethanes and epoxy resins. It enhances thermal stability and mechanical strength of the resulting polymers due to its flexible aliphatic chain and reactive ether linkages. Commonly employed in coatings, adhesives, and sealants where improved toughness and durability are required. Also serves as a chain extender in specialty elastomers, contributing to better elasticity and resistance to environmental degradation. Its hydrolytic stability makes it suitable for applications exposed to moisture.
