Will epoxy bond 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 polyethylene?

Does silicone bond to polyethylene?
100% silicone caulk makes an excellent glue/adhesive when attaching wood to plastic like polyethylene/polypropelene. Given that construction adhesives cannot grab onto hard plastics since plastics are non-reactive, 100% silicone caulk is an excellent alternative.
How do you fix cracked polypropylene?
Polypropylene glue is the best glue to use. The only way to successfully bond the plastic is to use hot melt glue that's made of polypropylene. Apply a small drop of the glue onto 1 surface and then press it firmly against the surface you want to connect it to. Hold them together until they fully set.
Can you melt polypropylene together?
Thermoplastic materials become liquid at their melting point (roughly 130 degrees Celsius in the case of polypropylene). A major useful attribute about thermoplastics is that they can be heated to their melting point, cooled, and reheated again without significant degradation.
What will bond polypropylene?
If you want to buy a polypropylene adhesive that can also be used on other plastics, your best option is Loctite Super Glue All Plastics. This super strength adhesive is the best glue for polypropylene; it bonds in just a few seconds and dries transparent.
How to fix a plastic patch?
Begin heating the patch by passing the heat gun over it. If you hold the heat gun over the patch for an extended period of time, you will burn it. Hold the heat gun over the patch for a few seconds, then check the patch. When it begins to melt, spread the liquid out towards the pilot holes. You must force the liquid polyethylene into the holes so the patch will adhere to the damaged plastic. Once you have filled the pilot holes with polyethylene from the melted patch, pour water on the patch to cure it.
How to repair a cracked HDPE?
Step 1. Assess the damage to the high-density polyethylene. If the plastic is cracked, measure the length. If it has a hole, measure the diameter. Score a piece of polyethylene from your scrap piece. Make it two inches longer than the crack and two inches wider, or two inches greater, than the diameter of the hole in the HDPE.
What is high density polyethylene used for?
High-density polyethylene plastic is used for a variety of purposes, including watercraft . High-density polyethylene plastic is used for purposes that require a greater tensile strength than that found in polyethylenes with less density. Many chemical containers, perishable foods, water containers, fuel tanks and plastic lumbers are made of HDPE.
Is HDPE plastic welded?
As a result, HDPE is easily plastic welded.
How to repair a crack in plastic?
If desired, you can sand the repair smooth, but this is not necessary. First, clean the plastic with EcoPrep plastic cleaner. Next, v-groove the crack with a die grinder, and then bevel the plastic around the crack. Use coarse sand paper or a 50 grit Roloc disc to roughen up the plastic.
What is crosslinked polyethylene?
Cross-linked polyethylene is a thermoset plastic, which means it is not meltable. The plastic identification symbols for cross-linked polyethylene are XPE, XLPE, PE-Xb, and PEX. If there is no identification symbol, the best way to determine if the polyethylene is cross-linked or thermoplastic is to try to melt it.

Can you use a nitrogen plastic welder to make fusion welds?
Because cross-linked polyethylene is not meltable, we cannot use the nitrogen plastic welder or airless plastic welder to create a fusion weld.
Does thermoplastic polyethylene melt?
Thermoplastic polyethylene will melt easily, but cross-linked polyethylene will not melt; t may turn brown or become soft and flexible, but it will not melt, as can be seen here. Now that we have determined we have cross-linked polyethylene, we can begin the repair process.
Can you use a 6031 flat tip welder?
Any Polyvance airless plastic welder with the 6031 flat tip can be used for this repair. However, you must use polyethylene welding rod. High density polyethylene welding rod can be used for this repair, but we recommend using low density polyethylene welding rod because it is easier to work with.
The Tank
I bought two 1550-gallon polyethylene tanks that I found on Craig’s list. I bought both for $450, which is about half of what one tank costs. Both tanks needed a little repair, but it was still a good deal. This post covers how to repair a crack. I’ll do another post in the future on how to repair a hole or gouge.
The Crack
The crack that I’m working on looks like it happened by an object hitting the tank and creating the crack with one half of the cracked piece knocked inward.
Clean
The first step was to clean the tank. I did this with a brush, water, and mild dish soap. I washed the outside of the tank just like I would a car. This prevents dirt and debris from getting into the repaired area. On the inside, the tank had some sand in it.
Level the Crack
The next step is to level the crack. Two pieces on either side of the crack do not line up, so I stuck a screwdriver in the crack and pried the inner piece out to line up with the outer piece.
The Welder
They make a kit for welding polyethylene. I bought my kit from Amazon and it cost just over $100. I’ll include a link to that below. The welding kit is like a big hot soldering iron with sticks of polyethylene that you use to fill in gaps.
Make a V
Plug the welder in and let it heat up. Then use the tip of the welder to melt the polyethylene on both sides of the crack, forming a “V” shape.
Fill the V
Then use the welder and supplied polyethylene sticks to fill the hole in the “V”. Be sure to get it hot enough to melt into the existing sides of the “V”.
What are the most common structural damage to a poly boat?

What is cosmetic damage on a boat?
Cosmetic damage is defined as something that impairs the boat’s appearance but not its function. On polyethylene boats cosmetic damage usually takes the form of abrasion, superficial slits, cuts or gouges, and localized dents in the hull panels.
Can you patch a boat hull?
It is possible to weld a patch to your hull but can be a tricky process. As its necessary to melt your existing hull surface at point of repair, the possibility of inadvertently further damaging your hull does exist. If possible,rehearse the process on a couple of scrap pieces of polyethylene before attempting on our boat. For best results, obtain a patch of adequate size from your boat’s manufacturer.
Can you repair a polyethylene kayak?
It’s safe to say that rotomolded polyethylene canoes and kayaks have revolutionized paddling. Boats made of this relatively inexpensive material are incredibly durable and abuse-tolerant as well as near maintenance free. If there is a downside to “roto” or “poly” boats, it is that should they be damaged, they are more difficult to repair compared to their ABS Royalex® and composite (fiberglass, Kevlar®, etc.) brethren. Indeed, some polyethylene boats are impossible to repair and some types of damage pose a major challenge whether it be a “home” based repair, a shop repair, or even factory based.
Can you melt poly with a torch?
torch with open flame is fine for generating heat necessary to conduct repair but it is not recommended to melt the weld rod poly directly with a torch. Use a drill bit as described to melt the rod.
