STARBOND Black Medium-Thick CA Glue 2 oz + 6 oz Accelerator Bundle

In this review the STARBOND Black Medium-Thick CA Glue bundle is evaluated for woodworkers and hobbyists who need a dark, impact-resistant adhesive for filling knots and reinforcing pieces. The bottom line: this kit pairs a 2 oz bottle of black medium-thick cyanoacrylate with a 6 oz aerosol accelerator to speed cures, and it stands out for its ability to blend into spalted wood and burl while providing shock absorbance where needed. It is best for projects that benefit from a dark adhesive rather than situations that require crystal clear fills.

Key Features

• Premium cyanoacrylate: Lab tested industrial grade formula provides reliable bonding and focuses on impact and shock absorbance for joined parts.
• Black medium-thick color: The dark tint hides imperfections, blends with spalted wood and burl, and accents voids instead of standing out.
• Included accessories: The 2 oz bottle ships with two applicator caps, a clog-free stopper and micro-tips for precise application in knots and tight areas.
• Controlled viscosity: At about 500 cps the syrup-like thickness penetrates small voids up to 0.008 in while staying workable for filling and shaping.
• Aerosol accelerator: The 6 oz accelerator speeds cure time when needed, reducing waiting on glue sets and allowing faster handling of parts.
• Shelf life warranty: A 30-month shelf life warranty is offered when stored under 40F, providing long-term confidence for occasional users.

Who It's For

This bundle is tailored to woodturners, luthiers and hobbyists who work with spalted, burl or dark-grained woods and need an adhesive that both bonds and visually integrates with the material. It is especially useful when filling dark knots, stabilizing edges, or accenting voids in decorative pieces.

Those who need clear, invisible fills for light-colored or transparent epoxies should look elsewhere, as the black tint is a deliberate design choice. Also, casual users unfamiliar with cyanoacrylate handling or accelerator spray techniques may want to practice on scrap before using on final pieces.

Pros & Cons

Pros

• Dark medium-thick formula blends with spalted wood and burl while adding impact resistance to repaired areas.
• Comes with practical extras like applicator caps, a clog-free stopper and micro-tips for precision work.
• 500 cps viscosity balances penetration and body, making it suitable for filling small voids up to 0.008 in.
• Aerosol accelerator cuts curing time when fast handling is required.

Cons

• Black color means it will not be suitable for projects requiring clear or light-colored fills.
• Drying time can vary; some users report longer set times without accelerator applied.

Our Verdict

For woodworkers and hobbyists who need a dark, impact-tolerant adhesive that blends into spalted wood and burl, this STARBOND bundle is a strong value because it combines a medium-thick black CA with practical applicators and a 6 oz accelerator to control cure times.

Frequently Asked Questions

Will the black glue show on light woods?
Yes, the black tint is visible on light woods, so it is best used with dark-grained or spalted materials where the color blends in.

How fast does the accelerator work?
The aerosol accelerator reduces cure time significantly, though exact speed depends on amount applied and environmental conditions; bonding time without accelerator is listed at 40-60 seconds.

What extras are included with the 2 oz bottle?
The bottle includes two applicator caps, a clog-free stopper and a bag of micro-tips for precision application.
