Wood & Stone Akabond 621 KG Part B — Hardener for Clear Knife-Grade Stone Epoxy (1 Quart)
Akabond 621 KG Part B is the hardener component of Wood & Stone's two-part clear knife-grade stone epoxy. Blended with Akabond 621 KG Part A resin (F015521) at a 2:1 ratio by volume, it triggers a solvent-free, zero-shrinkage cure that yields a strong, color-stable bond on light-colored marble, quartzite, and granite. Sized to match a 1/2-gallon unit of Part A.
