Description
High-Strength Adhesive for CarbonBar Brackets – Bonds to Stone, Quartz, and Itself
CarbonBond Structural Acrylic Adhesive – Black is a two-component, methacrylate-based structural adhesive engineered specifically for fabricators working with CarbonBar reinforcement systems. Whether bonding CarbonBar brackets to stone or laminating CarbonBar layers together for added rigidity, CarbonBond delivers weld-like strength, fast cure times, and long-term durability that outperform silicone and standard epoxies.
Trusted by professional countertop fabricators, this adhesive is purpose-built to maximize the performance of CarbonBar systems in overhang support, sink cutouts, and load-bearing applications. It offers strong adhesion to quartz, granite, engineered stone, and carbon fiber — with minimal surface prep required.
Key Features & Benefits
-
Engineered for CarbonBar Systems
Ideal for bonding CarbonBar to stone and for CarbonBar-to-CarbonBar lamination. -
High-Strength, Structural Adhesion
Tensile strength up to 3,500 psi ensures long-term bond integrity. -
Fast-Setting for Production Efficiency
12-18 minute working time and 35-50 minute fixture time -
Gap-Filling up to 1/4”
Excellent for uneven stone surfaces or layered CarbonBar assemblies. -
Outperforms Silicone and Construction Adhesives
Provides structural-grade adhesion where silicone fails — ideal for permanent reinforcement. -
Minimal Surface Preparation Required
Bonds stone, carbon fiber, and metals without excessive surface preparation.
Expanded Use Cases
1. CarbonBar to Stone Bonding
- Structural adhesion of CarbonBar brackets and rods to quartz, granite, and solid surfaces.
- Common in countertop overhangs, floating vanities, and bar top reinforcement.
2. CarbonBar Lamination
- Laminates multiple CarbonBar layers together for custom reinforcement profiles.
- Ideal for building multi-ply supports or increasing stiffness in high-load areas.
3. Mixed-Material Bonding
- Reliable adhesion between carbon fiber, stainless steel, aluminum, and fiberglass.
- Supports hybrid bracket designs or custom-fabricated support systems.

Why Fabricators Choose CarbonBond Over Silicone
-
Silicone offers a weak, flexible bond prone to peel or shift over time — not suitable for structural applications.
- Construction Adhesives outgas and have long skin and cure times, shrinkage issues are also a concern
-
CarbonBond delivers a rigid, vibration-resistant bond between CarbonBar and stone — or CarbonBar to itself — for permanent countertop reinforcement.
-
Faster cure, higher bond strength, and no primer required make it a superior choice for professional shops.
