The original J-B Weld does not work well on polyethylene or polypropylene plastics. Polyethylene is often used for water or gas containers or garden sprayers. Polypropylene is a harder plastic, durable enough for use on some car radiator parts.

What is the best adhesive for polyethylene?
Just one drop: that’s all you need to bond plastic surfaces such as polyethylene when you choose Loctite Plastics Bonding System. This two-part adhesive requires no mixing, you just prime and glue. It sets quickly and without clamping and offers incredible strength.
Does epoxy stick to polyethylene?
Epoxy will not bond polyethylene and polypropylene materials. Neither will polysulfide adhesives such as BoatLIFE Life-Calk, or polyurethane adhesives such as 3M 5200 or Sika-flex. Methacrylates are generally the type of adhesive to use to bond these dissimilar plastics.
Does J-B Weld work on plastic to plastic?
J-B WELD PLASTICWELD: A quick setting and multipurpose two part epoxy that provides a strong and lasting bond on various plastic surfaces (Plastic & PVC, Fiberglass, Glass, ABS, Composites and Vinyl).
Can you weld polyethylene?
The most important rule about welding polyethylene is that you can weld low to high but not high to low. Meaning, you can weld low density polyethylene (LDPE) welding rod to high density polyethylene (HDPE) sheet but not vice versa. Like PP, HDPE is weldable at 572°F/300°C.
Does anything stick to polyethylene?
It is often abbreviated to LDPE (low density polyethylene) or HDPE (high density polyethylene). Bonding polyethylene is considered very difficult and as a result it is often used as packaging for adhesive materials – as the glue won’t stick to it! Polyethylene has a low surface energy so is a fairly non-stick surface.
How do you weld high density polyethylene?
To weld HDPE material, feed the rod through the gun and apply pressure on the rod as the sheet and rod are heated simultaneously. The temperature of the gas should be at 575°F for a round nozzle, and 590°F with a high speed nozzle, when measured 3/16” inside the tip of the gun.
How do you stick polyethylene together?
Recycling Symbol 2: High Density Polyethylene (HDPE) What’s the best glue? Plastic cement, cyanoacrylates or epoxies will do the trick, however to ensure you get a strong bond its crucial to ensure you roughen up the surface before application.
How long does it take for J-B Weld to dry on plastic?
PlasticWeld™ sets in 5 minutes at room temperature and is fully cured in 1 hour. Using a 1:1 mixing ratio, PlasticWeld™ combines to a tensile strength of 3900 PSI and cures to a translucent yellow color.
What wont J-B Weld stick to?
J-B Weld will not adhere or bond well to: Any flexible rubber surface. Leather. Vinyl.
Can you heat weld polyethylene?
Polyethylene is a “thermoplastic”, meaning that it can be melted and reshaped with heat. When you weld PE, you perform a fusion weld, meaning that you melt the welding rod and base material together.
Can you ultrasonic weld polypropylene?
1. Ultrasonic Welding 20, 30, 35 kHz, Linear and Torsional. Welding dissimilar thermoplastic materials according to their polymer compatibility, such as PP, PVC, PE, PET, ABS, composites, tissues, fleece or films. Ultrasonic plastic welding is suitable for virtually all thermoplastics.
