ARALDITE® DY K

ARALDITE® DY K is a cresyl glycidyl ether (CGE). Liquid epoxy resins, based on bisphenol A and epichlorohydrin, are sometimes too viscous for use in certain applications. The viscosity of liquid resins can be reduced by the addition of solvents, plasticizers or reactive diluents. When formulating thick coatings, the incorporation of solvents is not recommended, since it is impossible to drive them off completely. Plasticizers cannot be tolerated in many electrical applications or where heat resistance properties are required. Reactive diluents are free-flowing compounds of low molecular weight (130-210) that take part in the curing reaction and considerably decrease the viscosity of an epoxy resin system. Although the addition of reactive diluents will always have some influence on the end properties of the cured resin/hardener system, they represent the best choice of viscosity reduction. Araldite DY K is less volatile and shows good resistance to water. Araldite DY K can be added to epoxy resins in quantities of 2-20% by weight. Additions of more than 20% cause considerable deterioration the properties of the cured system.
