Superior POLY-EPOXY Knife Grade Adhesive is a premium blend of polyester and vinyl ester resins, delivering the strongest bond available in a polyester-based formula. This advanced hybrid formulation provides superior adhesion on dense granite and all types of natural stone, making it the go-to choice for fabricators who demand maximum bonding strength.

The knife grade consistency is non-sagging, holding firmly on vertical and horizontal surfaces. Its exceptional bonding power makes it ideal for seaming dense, low-porosity stones where standard polyester adhesives may not achieve adequate adhesion.

Cured with 2%-4% white paste hardener (BPO). Can be tinted with Superior Stone Coloring Paste pigments for custom color matching.
