Zepoxy RER 169
Zepoxy RER 169 is a low viscosity Bisphenol-F epoxy resin, containing no diluent. Like other bisphenol F epoxy resins, it has improved chemical resistance and lower viscosity than bisphenol-A epoxy resins. The higher molecular weight of Zepoxy RER 169 provides some improvement in crystallization resistance versus other bisphenol-F epoxy resins. The low viscosity compared to bisphenol-A epoxy resins provides good fiber or pigment wetting and allows the use of less reactive diluents in formulations to achieve similar system viscosities and superior mechanical properties.
APPLICATIONS AREAS/SUGGESTED USESZepoxy RER 169 may be used alone or in mixture with other liquid resins, such as Zepoxy RER 128. In this latter instance, it provides a means of reducing viscosity and of conferring additional crystallization resistance to the resin blend. Typical uses include compositions for the building and civil engineering industries (e.g., flooring compounds, adhesives, mortars, and grouts), filament winding for composites, electrical castings, solvent-free and high solids coatings.
