Epotec YD 127 is an unmodified liquid epoxy resin with medium viscosity produced from bisphenol-A and epichlorohydrin. It’s viscosity is lower than epotec YD 128 and hence is preferred over epotec YD 128 where lower viscosity plays important role in processing and application.

Epotec YD 127 resin should be stored in original tightly closed container, in dry and warm conditions to avoid crystallization. Under these conditions, it has a storage life of at least two years from the date of manufacturing.
Epotec YD 127 may become hazy or crystallize upon long storage especially when exposed to low temperatures.
The resin can be restored to its original condition by warming to 55-60ºC while stirring.
For handling or pumping the maximum temperature recommended is 80ºC.
A wide variety of curing agents are available to cure this liquid epoxy resin at ambient conditions and also at elevated temperature.
