Super glue (cyanoacrylate) is the fastest way to fix small breaks in plastic, rubber, ceramic, and metal. We focused on gel formulas that don't run on vertical surfaces and on the one system that actually bonds slick plastics. Here are the picks that set fast and hold.
The go-to instant repair glue for small jobs on plastic, rubber, and metal. The gel body makes it far more controllable than watery super glues, and the impact-toughened cure holds up to knocks that would shatter a brittle CA bond.
- Instant repair
- Vertical surfaces
- Plastic
- Rubber
- Metal
Pros
- Thick gel stays put on vertical and overhead surfaces without dripping or running
- Impact-toughened formula survives drops and vibration better than thin CA glues
- Anti-clog cap with a metal pin keeps the nozzle sealed for repeated use
Cons
- Will not bond untreated polyethylene or polypropylene (needs a plastics primer for those)
- Sets in seconds, so misaligned parts can't be repositioned once contact is made
- Small 15g bottle dries out if the cap isn't seated perfectly between uses
A flexible, impact-resistant super glue that shines on parts that flex or get knocked around. The signature side-squeeze bottle is the most clog-resistant dispenser in the category, which is why half-used bottles actually stay usable.
- Instant repair
- Flexible bonds
- Outdoor repair
- Plastic
- Rubber
Pros
- Rubber-toughened bond flexes with impact, shock, and vibration instead of cracking
- Side-squeeze bottle dispenses from the sides, giving precise control and resisting clogs
- Water, chemical, and freeze resistant, so bonds hold up on outdoor and washed items
Cons
- Tiny 4g bottle empties fast on anything larger than small repairs
- Struggles with the same untreated PE/PP plastics as all standard CA glues
- Gel is thick enough that very fine, thin-line application can be tricky
The specialist for plastics that defeat normal super glue. The felt-tip activator chemically preps slick PE/PP/PTFE surfaces so the CA can grab, making it the answer for cracked tote lids, bumpers, and appliance housings.
- Hard to bond plastic
- Polypropylene
- Polyethylene
- Instant repair
Pros
- Activator primes polyethylene, polypropylene, and PTFE that ordinary super glue can't touch
- Bonds in about 30 seconds with no clamping or mixing required
- Dries clear and resists water, most chemicals, and freezing temperatures
Cons
- Tiny kit is single-repair-sized; the glue tube empties after a few jobs
- Two-step activator-then-glue workflow is slower and fussier than a one-tube glue
- Bond line is thin and rigid, so it needs well-fitting parts and no gap filling

Frequently Asked Questions
- Why won't my super glue stick to certain plastics?
- Polyethylene (PE) and polypropylene (PP) - common in totes, bumpers, and appliance housings - have low surface energy that standard CA glue can't wet. You need a two-part system with a surface activator, like the Loctite Plastics Bonding System, to bond them.
- Gel or liquid super glue - which should I use?
- Liquid CA wicks into tight, well-fitting cracks and sets fastest. Gel stays where you put it, so it's better on vertical or overhead surfaces and on porous materials like wood and leather. For most DIY repairs, a gel is more forgiving.
- How do I keep a super glue bottle from clogging?
- Wipe the nozzle after every use and seat the cap fully. Bottles with airtight caps (Gorilla's metal-pin cap) or side-squeeze bodies (Loctite Ultra) resist clogging far better than standard press caps.
