- Hard to bond plastic
- Polypropylene
- Polyethylene
- Instant repair
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.
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
- Does the Loctite Plastics Bonding System actually work on polypropylene and polyethylene?
- Yes, and that is the entire point of the two-part design. The felt-tip activator chemically preps slick PE, PP and PTFE surfaces so the cyanoacrylate can grab - these are the plastics ordinary super glue slides off. It also bonds PVC, ABS and acrylic.
- How fast does it set?
- About 30 seconds of hold after the activator, with no clamping or mixing, and full cure at 24 hours. The two-step activator-then-glue workflow is slower and fussier than a one-tube glue, so it is worth it for the plastics that need it rather than as an everyday adhesive.
- Can it fill a gap or bond a poorly fitting break?
- No. The bond line is thin and rigid, so parts must fit well and meet cleanly. If the break has a missing chip or a visible gap, this is the wrong product - it is a precision bonder, not a filler.
- How many repairs does one kit cover?
- Few. The 0.21 oz kit (0.14 oz activator plus 0.07 oz glue) is essentially single-repair sized and the glue tube empties after a few jobs. Buy it for a specific broken tote lid, bumper tab or appliance housing rather than as a shelf staple.
- Is the bond water and temperature resistant?
- It dries clear and resists water, most chemicals and freezing temperatures. We do not have a verified high-heat rating for this kit, so for a repair that will sit against a heat source, check the manufacturer's current technical data rather than assuming.
