K-Bond BPO 4 oz Hardener Tube (SKU HARD-70051)
Product Overview
The K-Bond BPO 4 oz Hardener Tube (SKU HARD-70051) is a Benzoyl Peroxide (BPO) hardener paste designed to catalyze and cure polyester adhesives and resin systems, especially in fabricating, bonding, and repair applications like natural stone, engineered stone, and composites. It’s supplied in a 4 oz (≈113 g) tube for convenient dispensing and mix-to-use hardening.
K-Bond Hardener Tube is a 4 oz tube of methyl ethyl ketone peroxide (MEKP) hardening agent formulated to catalyze and cure K-Bond polyester adhesives used in stone fabrication and repair. When mixed with K-Bond polyester resins at the correct ratio, this hardener initiates rapid polymerization, transforming the liquid resin into a solid bond or fill suitable for seaming, laminating, chip filling, and edge repair on natural and engineered stone. It is metered for consistent cure and is compatible with most K-Bond polyester adhesive systems.
