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 improved resistance to crystallization versus other bisphenol-F epoxy resins. Its low viscosity also provides good fiber or pigment wetting and allows the use of less reactive diluents in formulations to achieve similar system viscosities with superior mechanical properties.

APPLICATION AREAS / SUGGESTED USES

Zepoxy RER 169 may be used alone or in mixture with other liquid resins, such as Zepoxy RER 128. When blended, it helps reduce viscosity and provides additional crystallization resistance to the resin system. Typical applications include:

Building and civil engineering compositions (flooring compounds, adhesives, mortars, and grouts), filament winding for composites, electrical castings, solvent-free and high solids coatings.

BENEFITS

Lower viscosity without diluent
Good hardness development and mechanical properties, especially versus diluted resins
Improved resistance against crystallization, which can be enhanced further when blended with Zepoxy RER 128
Imparts good chemical resistance
Good pigment wetting
Good resistance to pigment settling
