1,6-Hexanediol diglycidyl ether is an organic chemical in the glycidyl
ether family. It is an
aliphatic compound that is a colorless liquid. It has two
epoxide (oxirane) groups per molecule. Its main use is in modifying
epoxy resins especially
viscosity reduction whilst flexibilizing.[2] It is
REACH registered.[3]
Its main use is for reduction of viscosity in epoxy resin systems - it is thus an
epoxyreactive diluent. The chain length helps give some degree of flexibility as an epoxy resin has rigid aromatic rings which are planar.[6] These systems may then be formulated into CASE applications:
Coatings,[7]Adhesives,
Sealants,
Elastomers, and
composite materials. The use of the diluent does effect mechanical properties and microstructure of epoxy resins.[8][9]
Toxicity
The toxicity is fairly well understood.[10] It is classed as a skin irritant, skin sensitizer, allergen and has caused
contact dermatitis.[11][12]
