O-Cresyl glycidyl ether
Chemical compound
From Wikipedia, the free encyclopedia
o-Cresyl glycidyl ether (ortho-cresyl glycidyl ether, o-CGE) is a liquid aromatic organic chemical compound and chemically a glycidyl ether.[2] It has the formula C10H12O2 and the CAS Registry Number 2210-79-9.[3] It is one of a number of glycidyl ethers available commercially that are used to reduce the viscosity of epoxy resins. These are then further used in coatings, sealants, adhesives, composites and elastomers.[4]

Uses
The main use of o-CGE is to reduce the viscosity of epoxy resins.[5][6] These reduced viscosity resins may then be used to formulate coatings including UV cured versions.[7] It is a monofunctional diluent and so in polymer science terms is a chain terminator. Chain extenders (f = 2) and cross linkers (f ≥ 3) are low molecular weight di or tri-functional epoxy diluents. The use of the diluent does effect mechanical properties and microstructure of epoxy resins.[8][9] As it has glycidyl functionality, it is classed as a Reactive diluent.
