O-Cresyl glycidyl ether

o-Cresyl glycidyl ether (ortho-cresyl glycidyl ether, o-CGE) is a liquid aromatic organic chemical compound and chemically a glycidyl ether. It has the formula C10H12O2 and the CAS Registry Number 2210-79-9. 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.Howarth G.A "Synthesis of a legislation compliant corrosion protection coating system based on urethane, oxazolidine and waterborne epoxy technology" pages 23,24,39 Master of Science Thesis April 1997 Imperial College London

Uses The main use of o-CGE is to reduce the viscosity of epoxy resins. These reduced viscosity resins may then be used to formulate coatings including UV cured versions., application discontinued outside South Korea. 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. As it has glycidyl functionality, it is classed as a Reactive diluent.

Other names o-CGE is known by a number of other names. These include: Oxirane, 2-[(2-methylphenoxy)methyl]- Propane, 1,2-epoxy-3-(o-tolyloxy)- Oxirane, [(2-methylphenoxy)methyl]- 2-[(2-Methylphenoxy)methyl]oxirane 1-(o-Methylphenoxy)-2,3-epoxypropane

Toxicology The material is a skin irritant and skin sensitizer. The toxicology has been reasonably well studied. It is REACH registered and produced or imported into the European Union in quantities greater than one thousand tonnes per annum.
