The EPX3-420 is a two-component resin adhesive-grout particularly suitable for anchoring into asphalt. The grout can be applied at temperatures as low as 14ºF.
The grout fills the crevices in the asphalt as it cures, forming a strong mechanical bond with the asphalt on the one hand, and with the anchor on the other. This is a stress-free bond that does not weaken with time.
The EPX3 is supplied as a single 10 oz. cartridge that fits a single-tube caulk gun. We recommend the use of our CG26 hi-thrust caulk gun with 26:1 mechanical gain. The cartridge contains both parts of the resin. A static mixing nozzle (shown next to the cartridge in the picture on top of the page) fits on the thread at the top of the cartridge, and will discharge a proper mix of the two resin components. One nozzle is supplied with the cartridge.
The EPX3 is suitable for use where it may come into contact with potable water. For best results use this product before Fall 2021.

The mixing of the two parts of the resin through the nozzle requires a fair amount of force to be applied to the cartridge. We strongly recommend the use of high-thrust (26:1) caulking guns. We have tested JES M26S with favorable results, but there are other products on the market such as Dripless HR300 and Albion B26 which will work just as well.
For full installation instructions, see our Anchor Installation Guide V6. Below are the simplified instructions.
Cure time The grout can be applied at asphalt temperatures from 14°F to 104°F. However, below 23ºF the grout itself needs to be preconditioned to 68F. The table below shows working time and cure time as a function of ambient and asphalt temperatures:
When kept at temperatures between 41ºF and 77ºF, shelf life is 18 months.
