Gorilla Super Glue Gel
Gorilla
- ✓Gel formula - no run
- ✓45-second cure
- ✓Impact resistant
- ✓Works on rough surfaces
Pros
- Gel formula does not run on vertical surfaces or porous materials
- Impact-resistant formula reduces the brittleness common in standard CA glues
- 45-second handling strength - faster than most gel CA products
- Works on ceramic, plastic, metal, and rubber
- Anti-clog cap - dries less frequently in storage
Cons
- Gel slightly reduces capillary action - slower wicking into tight joints than liquid CA
- Larger bottle size dries out faster if used infrequently
Best overall super glue. Gel formula with impact resistance and anti-clog storage. The most capable general-purpose cyanoacrylate tested.
Loctite 495 Super Bonder Industrial Grade
Loctite
- ✓Industrial ethyl cyanoacrylate
- ✓Low viscosity
- ✓Wicks into tight joints
- ✓3,000+ PSI bond strength
Pros
- Industrial formulation - higher purity and consistent cure vs consumer grades
- Low viscosity wicks into tight-fitting joints via capillary action
- 3,000+ PSI tensile strength - higher than most consumer CA glues
- Loctite industrial standard used in manufacturing
Cons
- Liquid formula runs on vertical surfaces and porous materials
- Higher price than consumer alternatives
Best industrial super glue. For tight-fitting precision joints where capillary wicking is needed. Loctite's industrial grade produces higher and more consistent bond strength.
Loctite Ultra Gel Control Super Glue
Loctite
- ✓Side-squeeze applicator
- ✓Controlled dispensing
- ✓Rubber-toughened gel
- ✓No-run formula
Pros
- Side-squeeze bottle provides more control than top-press bottles
- Rubber toughener in formula reduces brittleness
- No-run gel suitable for overhead and vertical applications
Cons
- Slightly slower cure than standard liquid Loctite
Best controlled-dispense super glue. Side-squeeze applicator for precise application on small repairs where excess glue is difficult to remove.
Krazy Glue Home and Office Pen
Krazy Glue
- ✓Pen applicator
- ✓Precise tip
- ✓Fast cure
Pros
- Pen format - precise application for small repairs on electronics, jewelry, model kits
- Fast cure for handling
- At $5, inexpensive precision CA applicator
Cons
- Small reservoir - runs out quickly
- Pen tip can clog
Best precision super glue applicator. For detailed repairs requiring exact application where standard bottles apply too much.
Bob Smith Industries Super-Gold Thin Cyanoacrylate
Bob Smith Industries
- ✓Water-thin viscosity
- ✓Wicks into wood grain
- ✓2-second cure with activator
Pros
- Thinnest viscosity CA tested - penetrates wood grain, balsa, and porous surfaces
- Standard in model building and RC hobby - proven in precision application
- BSI brand is respected in hobby and craft community
Cons
- Runny - difficult to control on horizontal surfaces
- Specialty product not available in hardware stores
Best thin CA for wood and porous materials. Hobby and model builder standard for wood grain strengthening and small joint bonding.
Starbond EM-02 Super Fast Thin CA
Starbond
- ✓Thin CA for woodworking
- ✓Wicks into grain
- ✓Longer shelf life
Pros
- Woodturners and luthiers standard for grain stabilizing and repair
- Longer shelf life than BSI products
- Available in multiple viscosities from same brand
Cons
- Specialty product at higher price
Best woodworking CA. For lathe work, grain stabilizing, and wood crack repair. Starbond is the professional woodturner choice.
Henkel Loctite 401 Multi-Substrate Instant Adhesive
Loctite
- ✓Industrial formulation
- ✓Bonds challenging substrates
- ✓Fast cure
Pros
- Loctite 401 is rated for difficult substrates including some rubbers and oily metals
- Industrial quality and consistency
Cons
- High price for a CA adhesive
- Overkill for standard plastic and ceramic repairs
Best multi-substrate industrial CA. For bonding challenging materials including oily metal surfaces where consumer CA fails.
Gorilla Super Glue (Liquid)
Gorilla
- ✓Liquid CA
- ✓Fast-set
- ✓Gorilla anti-clog cap
Pros
- Liquid CA - faster capillary action than gel on smooth metal and plastic
- Anti-clog cap extends shelf life
- Gorilla's broad retail availability
Cons
- Runs on vertical and porous surfaces
Best liquid Gorilla glue. For smooth-surface metal and plastic bonding where capillary action is preferred over gel thickness.
Zap-A-Gap CA+ Medium Cyanoacrylate
Pacer Technology
- ✓Medium viscosity
- ✓Gap filling
- ✓RC and model standard
Pros
- Zap-A-Gap is the RC car and airplane building standard
- Medium viscosity between thin and gel - versatile across joint types
- Slightly more gap-filling than thin CA without the runniness
Cons
- Less common in hardware stores than Gorilla or Loctite
Best medium viscosity CA. For model building and hobby repair where gap filling matters but thin CA is too runny.
Super Glue 15187 Gel Tube
Super Glue Corporation
- ✓Budget gel CA
- ✓Tube dispensing
Pros
- At $3.50, lowest cost CA gel tested
- Tube applicator allows controlled squeeze
Cons
- Lower bond strength than premium CA products
- Shorter shelf life than anti-clog bottles
Best budget super glue. For occasional use where cost is the priority and joint strength requirements are low.
Super glue (cyanoacrylate) comes in liquid and gel forms, with significant differences in viscosity and cure speed that determine which application each is suited for.
Liquid vs Gel Cyanoacrylate
Liquid CA: wicks into tight joints via capillary action. Correct for precision-fit joints in metal, ceramic, and hard plastic. Runs on vertical surfaces and soaks into porous materials.
Gel CA: stays in place on vertical surfaces and porous materials. Does not wick into joints - requires surface contact. Better gap-filling than liquid. The correct choice for most household repairs.
Accelerator
Cyanoacrylate accelerator (Loctite 712, Bob Smith Industries) sprayed on one surface before applying CA reduces cure time from 45 seconds to under 5 seconds. Use when working time is critical or humidity is low (dry conditions slow CA cure).
Why Super Glue is Brittle
Cured cyanoacrylate has low impact and peel strength. A joint that is pulled apart (peel) rather than sheared breaks at much lower force than the rated tensile strength. Rubber-toughened formulas (Gorilla Super Glue Gel) partially address this.
Do not use CA on joints that will be pulled apart, flexed repeatedly, or exposed to sustained vibration.
