Aliphatic glycidyl ether made from C12-14 fatty alcohol and epichlorohydrin. A mixture of alkyl chain lengths, not a single discrete compound, so no fixed molecular formula applies — the epoxy equivalent weight below is the meaningful molecular-scale measure for this product. Lowers the viscosity of liquid epoxy resin while adding flexibility, used as a reactive diluent in floor and concrete-repair formulations and in filament winding.
