Butyl glycidyl ether is widely used as a reactive diluent in epoxy resin formulations, helping to reduce viscosity and improve processing without compromising the resin's properties. It is particularly valuable in coatings, adhesives, and composites, where it enhances flexibility and adhesion. In the electronics industry, it is employed in encapsulants and potting compounds to provide insulation and protection for components. Additionally, it serves as an intermediate in the synthesis of specialty chemicals, including surfactants and plasticizers, due to its ability to introduce glycidyl groups into molecules. Its versatility makes it a key component in various industrial applications.
