RE500 Epoxy – Think Pink?

There are many resins in use by climbers for installing glue-in bolts and Hilti RE500 epoxy resin is but one of them. Hilti RE500 is a premium performing epoxy that will cure underwater, designed for high strength in smooth holes (diamond drilled in the construction industry), has long term stability and capable of resisting very high loads.

The vibrant colour of freshly mixed RE500 is sometimes cited as a drawback or issue associated with using this particular resin. The reality is that over time, the initial red colour fades, and with it fades the relevance of colour.
