STARBOND Black Medium-Thick CA Glue Pro Kit (2 oz) — Rubber-Toughened, Impact-Resistant for Woodworking & Instrument Repair

STARBOND Black Medium-Thick CA Glue Pro Kit is a rubber-toughened, impact-resistant cyanoacrylate adhesive designed to fill knots and cracks, bond dark woods, and absorb vibration where ordinary super glues fail.

This professional kit delivers a medium-thick (motor-oil consistency) black CA formula that wicks into gaps, resists brittleness, and blends seamlessly with ebony, walnut, and stained surfaces. Manufactured in small batches since 1988 to preserve freshness and strength, the glue is engineered for woodworking, instrument repair, RC and hobby projects, and any application where a durable, discreet bond is needed. The kit includes precision tips and anti-clog caps to make accurate application simple and waste-free.

How does the rubber-toughened formula help my project?

The integrated rubber modifiers make the cured adhesive less brittle than standard CA glues, helping it absorb shock and tolerate light flex without cracking. This characteristic is particularly useful on vibrating or load-bearing joints and for knot or crack filling where movement is expected.

• Improved impact resistance over plain cyanoacrylate
• Better performance on vibrating surfaces like guitars and tools
• Reduced risk of cured glue fracturing under stress

Will the black color match my dark woods and finishes?

Yes — the black pigmentation is formulated to blend with ebony, dark-stained hardwoods, black epoxy and other dark materials, minimizing visible repair lines. The color also helps hide filled knots and small inlays so repairs remain discreet after sanding and finishing.

• Conceals fills in dark woods and veneers
• Sands smoothly for flush finishing and clearcoats
• Works well under stains and lacquers when pretested

How easy is it to control and apply this medium-thick CA?

The medium-thick viscosity gives a controlled flow that wicks into cracks without running, letting you fill gaps and bond edges without excessive squeeze-out. The Pro Kit’s micro-tips, spare nozzles and anti-clog caps provide precise placement for delicate tasks and repeatable results.

• Motor-oil consistency for measured application
• Micro-tips and nozzles for tight or detailed work
• Anti-clog caps extend usable life and reduce waste

What shelf life and storage practices should I expect?

Starbond produces adhesives in small batches to maintain potency; when stored correctly the product offers long shelf stability. Refrigeration between uses and sealing the bottle with the anti-clog cap help preserve freshness and extend effective life.

• Made in small batches for consistent strength
• Proper storage can extend shelf life up to around 20 months
• Kit tools reduce contamination and premature curing inside the bottle

Who is this for: The STARBOND Black Medium-Thick CA Glue Pro Kit is aimed at woodworkers, luthiers, instrument technicians, model builders, RC hobbyists, and makers who need a durable, low-profile repair adhesive. It’s ideal for anyone repairing or reinforcing dark woods, filling knots/cracks, or bonding parts exposed to vibration. If you want precise application, impact-resistant cured bonds, and a discreet black finish, this kit provides the tools and formula to get professional-looking results.
