PlasticWeld will bond a variety of surfaces, such as metal, composites, fiberglass and others. 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 an off-white color. Additional Attributes All J-B Weld Syringes have a unique dispensing system allowing customers to re-seal the product, which prevents air from curing the epoxy or adhesive, so they can use it multiple times. J-B Weld also provides a mixing tray and stick in the package so you can get to work right away! Review: Make shore it’s fully set hard before working on it - I have used this product to repair a plastic frame it’s easy to mould and once set a Dremel can shape it to get fine detail and it seem quite sturdy Review: Used for interior car door handle repair job - I bought this for my husband to repair the interior car door handle on the driver side. The part he needed was hard to find and to take the car to be repaired would cost hundreds, this was decided on as a temporary solution. Next day delivery, inexpensive and easy to use, we can’t complain. It says you need protective gloves and clothes (but how much less are you going to make?). He tried gloves but it was easier to use bare handed - be quick to wash the putty off afterwards. He just kneaded the putty and smoothed a very small amount over the cracked plastic and held the handle in place for a couple of minutes. It cured after about 20 minutes. A few days of use in and out the car and the handle seems to be holding up. We may not need to get the spare part after all. ## Features - Causes serious eye irritation. - Causes skin irritation. - Harmful to aquatic life with long lasting effects. - May cause an allergic skin reaction. - May cause respiratory irritation. - FAST SETTING Provides a fast repair by setting in just 5 minutes. - HIGH STRENGTH Exceptionally high strength provides a hard permanent repair to almost anything. - MULTIPLE MATERIALS - Perfect for use on hard plastics, ABS, Fiberglass, PVC, Glass, Vinyl and other composites. - ENVIRONMENTAL RESISTANCE - Resistant to water, chemicals and heat. - Bonding Strength 3900PSI - Set Time 25 Minutes - Cure Time Cure 3 Hour ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003S2E4UE | | Best Sellers Rank | 2,268 in DIY & Tools ( See Top 100 in DIY & Tools ) 3 in Metal Filled Epoxies | | Brand | J-B Weld | | Colour | Off-White | | Compatible Material | Plastic | | Container Type | Stick | | Country Of Origin | USA | | Customer Reviews | 4.2 out of 5 stars 9,906 Reviews | | Full Cure Time | 3 Hours | | Global Trade Identification Number | 00043425008374, 00043425082374 | | Included Components | Glue | | Item Form | Putty | | Item Package Quantity | 1 | | Item Type Name | JB WELD JB8237 Plastic Weld Fast-Setting Off White Multi Purpose Reinforced Epoxy Putty, 57 G | | Item Volume | 59.14 Millilitres | | Item Weight | 57 Grams | | Item form | Putty | | Manufacturer | J-B Weld | | Manufacturer Part Number | 8237 | | Material | Epoxy Resin | | Model Number | 8237 | | Other Special Features of the Product | Quick drying, strong | | Product Warranty | Na. | | Special feature | Quick drying, strong | | Specific Uses For Product | Cars, Construction, Plastic | | Specific uses for product | Cars, Construction, Plastic | | Tensile Strength | 3900 Pounds Per Square Inch | | UPC | 043425082374 043425008374 043425700063 798304344912 | | Unit Count | 57.0 gram | | Viscosity Level | High | | Water Resistance Level | Water Resistant | ## Product Details - **Brand:** J-B Weld - **Item form:** Putty - **Material:** Plastic, Rubber - **Special feature:** Quick drying, strong - **Specific uses for product:** Cars, Construction, Plastic ## Images ![JB WELD 8237UK JB8237 Plastic Weld Fast-Setting Off White Multi Purpose Reinforced Epoxy Putty, 57 G - Image 1](https://m.media-amazon.com/images/I/71PhEFDPrHL.jpg) ![JB WELD 8237UK JB8237 Plastic Weld Fast-Setting Off White Multi Purpose Reinforced Epoxy Putty, 57 G - Image 2](https://m.media-amazon.com/images/I/71iSEzRY5DL.jpg) ![JB WELD 8237UK JB8237 Plastic Weld Fast-Setting Off White Multi Purpose Reinforced Epoxy Putty, 57 G - Image 3](https://m.media-amazon.com/images/I/71EbWzSIksL.jpg) ![JB WELD 8237UK JB8237 Plastic Weld Fast-Setting Off White Multi Purpose Reinforced Epoxy Putty, 57 G - Image 4](https://m.media-amazon.com/images/I/71cq6T9LiDL.jpg) ![JB WELD 8237UK JB8237 Plastic Weld Fast-Setting Off White Multi Purpose Reinforced Epoxy Putty, 57 G - Image 5](https://m.media-amazon.com/images/I/716f6kZtzEL.jpg) ## Questions & Answers **Q: can u recommend anything for a metal spring that connects to a plastic holder, as the spring keeps coming out of its holder** A: JB Plastic weld but is not a complete solution as it will work loose eventually. I do not know a glue for this combination. The connection must depend on the basic design, not a glue. **Q: I have a crack in the rear moulding of a caravan. It is subject to vibration and bouncing when being towed. Will this be suitable?** A: This is the best glue i have used on plastic. I have used it to repair some parts of a machine and this give out a high degree of vibration. These repairs were to be temporary but they are still holding after several months. Give the glue time to set (24 hours), before you place to much stress on the repair. Hope this was helpful. William **Q: Anyone know if this is the right stuff to fix a crack in a car roof box thanks** A: If it helps my father used it to fix a crack in his oil tank so I don't see why you couldn't use it on a roof box. **Q: Will this work on glass reinforced plastic (grp) which is polyester resin, glass fibre reinforcement and usually a silica sand filler?** A: Yes ## Customer Reviews ### ⭐⭐⭐⭐⭐ Make shore it’s fully set hard before working on it *by M***Y on 19 May 2026* I have used this product to repair a plastic frame it’s easy to mould and once set a Dremel can shape it to get fine detail and it seem quite sturdy ### ⭐⭐⭐⭐ Used for interior car door handle repair job *by A***I on 22 February 2025* I bought this for my husband to repair the interior car door handle on the driver side.

The plastic mounting bracket had been snapped completely. According to Nissan, my only option was a complete new mirror at around £300. Or was it? With only a few centimetres of 'surface' I wanted to try sticking the mirror casing back onto the mount. But the mirror is heavy - it has a camera and electric motors behind the glass and I thought it would be too heavy to stay stuck with such limited surface area, particularly when the car would be bouncing on roads, driven at speed on motorways etc. So I found this product and tried it before spending big money. Nothing to lose, right? I used the putty on both edges, held it together for maybe 10 minutes and it bonded. So far so good. I then left the whole thing for 2 days (I know you don't have to leave it that long, but I didn't need the car) before screwing it all back together. I sanded and painted over the white/grey residue (black) and hoped for the best. I took it for a short test drive, fully expecting the mirror to fall over when I hit the first bump. That was 2 months ago. Absolutely perfect. Solid as a rock. Great product. And saved me £300. ## Frequently Bought Together - J-B Weld 8237 PlasticWeld Plastic Repair Epoxy Putty - 2 oz. - J-B Weld 50139 Plastic Bonder Body Panel Adhesive and Gap Filler Syringe - Black - 25 ml - J-B Weld 50133 Plastic Bonder Structural Adhesive Syringe - Tan - 25 ml --- ## 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.uk/products/47943756-jb-weld-8237uk-jb8237-plastic-weld-fast-setting-off-white](https://www.desertcart.co.uk/products/47943756-jb-weld-8237uk-jb8237-plastic-weld-fast-setting-off-white) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-01*
