The PR100 instant adhesive is formulated to give exceptional performance on difficult-to-bond substrates, such as EPDM, nylon, polypropylene and polyethylene with use of an appropriate primer. Once applied, the glue has fast handling time and cure to keep jobs moving quickly. Pinch Container for a Precise Drop or Squeeze for a Steady Bead Our 3M Scotch-Weld Plastic & Rubber Instant Adhesive PR40 is a glue that is easily applied with a thin bond line from a squeeze bottle and cures quickly. This cyanoacrylate adhesive is dispensed from a flexible container; pinch a precise drop or squeeze for a steady bead.

Once a full cure is achieved, the glue achieves a strong, durable and lasting bond, with overlap shear strength over 2,000psi. Plastic and Rubber Instant Adhesives Our 3M™ Scotch-Weld™ Plastic and Rubber Instant Adhesives are designed to give exceptional performance on difficult-to-bond plastic and rubber substrates. These adhesives may be bonded to like substrates or in combination with metal or composite substrates. Understanding Instant Adhesives Instant adhesives are cyanoacrylate based formulas that are strong, fast-acting glues used in industrial and household applications. In general, they are an acrylic resin that rapidly polymerizes in the presence of moisture, forming long, strong chains, joining the bonded surfaces together. Cyanoacrylate adhesives should be applied thinly, with pressure put on the bond for a few seconds, to ensure that the reaction proceeds rapidly and a strong bond is formed within a reasonable time. 3M instant adhesives apply right from the container and rapidly reach handling strength at room temperature. Commonly referred to as a super glue, a single drop per square inch can bond many plastics, rubbers, metals, wood and more. An instant adhesive from 3M set a Guinness World Record in 2012 for the strongest glue by lifting an 8.1 metric ton forklift in the air for one hour.

Review: Excellent bonding for HDPE to PLA. - This adhesive worked great for my project which was to bond some 3D printed (PLA) items to polyethylene (HDPE). After 24 hours of curing the two items were bonded together as if they were one. There was a lot of surface area for the connection that I was bonding so perhaps my situation was optimal for this product but I couldn't be happier with the result. There's not a lot of instructions included, so it might be helpful to know how I used the product: - I started with both surfaces to be bonded in a horizontal position. The adhesive (and the primer are very thin and runny and this is the only way to minimize the mess. - I masked off the non-bonding areas with blue painters tape to further reduce mess. - I first primed the pieces by brushing the entire (cleaned) area for be bonded with acetone. Acetone is cheap and I had some (from Home Depot) so I decided to try it as an alternative to the expensive but official 3M primer. - I applied a thin layer of adhesive to the HDPE side, spreading it about a bit with a wooden stir stick. - I joined the pieces, clamped them together and carefully wiped away the excess with a paper towel. Note that the bonding is not immediate. Out of an abundance of caution I left the clamps on for 24 hours. Maybe another process would work as well, but that worked great for me. You end up using a very small amount of adhesive so the little bottle goes farther than you might think. To be honest I had serious doubts that anything would work to bond HDPE, and was amazed at how well it ended up working. Good luck! Review: Very impressive rubber bonding great for diy seals/gaskets - Very impressive bonding specially rubber to rubber applications. And dries fairly quickly on its own but fastest with a CA activator. ## Features - Bonds to a number of substrates, including plastics and rubbers - Precise application: pinch container for a precise drop or squeeze for a steady bead - Low viscosity adhesive is easily applied from the bottle - Strong, durable and long lasting bond on a variety of substrates - Fast curing to keep projects moving quickly - For industrial/occupational use only.

If they are metal, you'd be best off scuffing the metal with sandpaper to ensure adhesion; for plastic this won't be a problem. **Q: This product was the result of a search for best ceramic glues. Is it good for antique china repairs?** A: Not my first choice **Q: Will this glue bond silicone rubber to silicone rubber?** A: Yes it will. **Q: do you need to use a primer?, can I use it fix my cracked kicking fin for swimming (silicone/rubber), need to be a strong bond** A: No. I used it on my tennis shoes. I just cleaned the area with alcohol. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent bonding for HDPE to PLA. *by D***T on December 27, 2023* This adhesive worked great for my project which was to bond some 3D printed (PLA) items to polyethylene (HDPE).

And dries fairly quickly on its own but fastest with a CA activator. ### ⭐⭐⭐⭐⭐ This stuff is great! *by H***A on August 16, 2022* I did a ton of research trying to find a glue to bond a soft plastic tablecloth fabric to a hard smooth plastic surface. I knew the usual glues that i use in my crafts were not going to adhere to the hard plastic. This stuff really works exceptionally well! It did not melt my fabric at all either. There was one small section that had some regular material as reinforcement over the hinge (that I left in place) that had some other kind of glue under it and there was a tiny amount of smoke when I glued over that but it was only for an second or two. I'm super grateful for the advice to wear gloves because my hands definitely would have been covered had I not because it is very runny. I also used shop towels to both absorb any excess glue and to press things into place - that worked great too. I'll definitely be purchasing more of this glue for future projects. I noticed that the directions on amazon mentioned using a bonding primer when joining polypropylene and polyethylene and I wasn't sure if I needed that but I didn't. I'll definitely be purchasing the primer too in case I need it in the future with this glue. BTW, I found the directions on the bottle impossible to read even with my bifocals! I highly recommend getting this glue!!! ## Frequently Bought Together - 3M Scotch-Weld Plastic & Rubber Instant Adhesive PR40, Clear, 20 Gram Bottle - 3M Scotch-Weld Instant Adhesive Primer AC79, Clear, 2 fl oz Bottle - 3M Scotch-Weld Plastic & Rubber Instant Adhesive PR1500, Clear, 20 Gram Bottle --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/61425631-3m-scotch-weld-plastic-and-rubber-instant-adhesive-pr40-clear](https://www.desertcart.co.za/products/61425631-3m-scotch-weld-plastic-and-rubber-instant-adhesive-pr40-clear) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-04-24*
