Zap a Gap
Zap-a-Gap (manufactured by Pacer Technology) is a legendary, medium-viscosity ethyl cyanoacrylate super glue celebrated by fly tiers, scale modelers, woodworkers, and archers for its exceptional gap-filling capability, rapid 20-second cure time, and ability to bond oily or mismatched surfaces.
Zap Cyanoacrylate Glue Formulas Comparison
Comparing viscosity, curing speeds, and specialty applications across the Pacer Zap adhesive lineup.
| Zap Adhesive Formula | Viscosity (Thickness) | Gap Filling Capacity | Best Craft Application |
|---|---|---|---|
| Zap-a-Gap (CA+ / Green Bottle) | Medium Viscosity (100 - 150 cP) | Fills gaps up to 0.006 - 0.010 Inches | Fly tying, arrow fletching, woodturning crack fills |
| Zap CA (Pink Bottle) | Water-Thin Ultra-Low Viscosity (5 cP) | Zero gap (Wicks into tight balsa joints) | RC airplane balsa wood frames & micro joints |
| Slo-Zap (Yellow Bottle) | High-Viscosity Thick Gel (1,500 cP) | Maximum Gap Filling (0.020 Inches) | Plastic models, heavy repositioning work (60s set) |
How to Use Zap-a-Gap and Kicker Accelerator in 4 Steps
Follow this instant bonding technique.
Step 1: Clean and Dry Both Contact Surfaces
Ensure parts are free of dust, wax, and grease for optimal molecular bonding.
Step 2: Apply a Single Drop of Zap-a-Gap CA+ to One Surface
Use sparingly; excess super glue slows curing and reduces tensile strength.
Step 3: Press Parts Together Firmly for 15 to 20 Seconds
Hold parts in exact alignment while atmospheric humidity triggers polymerization.
Step 4: Spray Zip Kicker Accelerator for Instant Curing
Mist Zip Kicker accelerator to instantly harden surface glue for immediate sanding.
Frequently Asked Questions (7 Questions Answered)
Q1: What is the difference between Zap-a-Gap and regular Krazy Glue?
Standard super glue is water-thin and runs off vertical surfaces; Zap-a-Gap CA+ has a medium honey-like viscosity engineered to bridge micro gaps between uneven parts and bond porous wood and leather.
Q2: Why do fly fishermen and fly tiers love Zap-a-Gap?
Fly tiers use Zap-a-Gap to secure thread wraps, lock dumbbell eyes to hook shanks, bond foam popper bodies, and create indestructible saltwater streamers that survive toothy fish strikes.
Q3: What is Zip Kicker and do you need it with Zap-a-Gap?
Zip Kicker is an aerosol solvent accelerator that cures Zap-a-Gap instantly (in 1 to 2 seconds) on contact, allowing woodworkers to fill knots and sand immediately.
Q4: How do you unstick fingers glued with Zap-a-Gap?
Apply 100% pure acetone (nail polish remover) with a cotton ball to dissolve the cyanoacrylate polymer bond, then gently roll skin apart (never tear skin).
Q5: Can you use Zap-a-Gap on plastic models and miniatures (Warhammer)?
Yes! Zap-a-Gap bonds resin, pewter, and polystyrene miniature parts instantly and can be filed and sanded smooth without chipping.
Q6: Does Zap-a-Gap work on flexible rubber or silicone?
It bonds rubber and O-rings exceptionally well, but will not adhere to oily silicone or polyethylene/polypropylene plastics without a surface primer.
Q7: How should you store Zap-a-Gap to keep it from drying in the bottle?
Wipe the nozzle clean, snap the cap tight, and store the bottle upright in a cool, dry place (or refrigerator inside an airtight ziplock bag).
