New WWA formulation

For the past 20 years, the WWA epoxy resin system has been a reference and a premium choice for clear castings thanks to its low refraction index, clarity, excellent degassing properties and low exotherm . Like all thermosetting resins though, a slow yellowing of the resin could be observed upon ageing, and outside use was not recommended due to poor UV stability.


Our R&D team has been testing a great number of additives combination over the years in order to slow or stop this yellowing in time. We are happy to announce that highly positive results have been obtained over the summer and we have decided to modify the WWA formulation, incorporating these additives in the WWA resin.
