The mid-size catalyst for Tenax polyester stone adhesives. Tenax Hardener Extra White Paste (118ml / 4 oz) activates and cures Tenax knife grade polyester, Travertine Filler, Solido Quarzo, Titanium Flowing, Titanium Knife Grade, and other polyester-based adhesive systems. The extra white paste formula minimizes color impact on light-colored adhesives and stone repairs. The 118ml size is the standard shop size — enough for regular daily use without the bulk of the 180ml. For occasional repairs or field kits, see the 45ml. For high-volume production shops, see the 180ml.
