ALECPEA Upgrade T-7000 Black Adhesive Glue - 2PCS 15ml | High-Performance Waterproof Adhesive for Precision Repairs, Perfect for Phone, Electronics, Jewelry, and Crafts

This worked out really well. Never used it before. Replaced the battery in my Galaxy and needed to securely attach the back cover. The original adhesive wasn't going to reseal. So, I scraped off all the old adhesive from the phone and applied a continuous bead of the T-7000 where I had scraped off the original adhesive. After replacing the back cover onto the phone, I secured it with multiple rubber bands, which helped to apply pressure to the seal, fixing the back cover firmly onto the phone. I don't know if it restores the waterproof capability of the OEM seal, but it's been a solid seal so far.

My son cracked the corner of his tablet screen and there was a significant gap between the screen and the rest of the tablet on the top left side. I applied this then put it under something heavy and it worked like a charm. The excess was also easy to remove. Happy with my purchase.

The ALECPEA T-7000 Black Adhesive works really well for everyday fixes. It creates a strong bond on plastic, metal, rubber, and other materials, and the waterproof formula makes it reliable for items that may get wet. I also like that the black color blends in nicely on dark surfaces. It doesn’t dry instantly, so you need to let it cure fully for the best hold, but once it sets, it’s very solid. The 2-pack is a good value and perfect for keeping a backup tube handy. Overall, a dependable adhesive for DIY repairs and small projects. Would buy again. 👍

The Alecpea Upgrade T-7000 adhesive is a versatile, multi-purpose glue that’s clearly designed with precision work in mind and that's what I needed. I got it primarily for phone and electronics repair, but it also performs well across a lot of materials including metal, plastics and rubber. What immediately stands out is the fine needle applicator tip, which allows for controlled, detailed application—an essential feature when working on delicate components like smartphone screens or small jewelry pieces like my daughter's necklace. It a practical option for both occasional users and frequent DIYers. Performance-wise, this adhesive delivers strong bonding capability with a semi-flexible finish once cured. That flexibility is a major advantage over brittle glues, especially for electronics that experience slight movement or pressure. Like most T-7000 formulations, it’s designed to be waterproof and resistant to wear after full curing, which typically takes about 72 hours though This makes it particularly effective for sealing phone frames or repairing items exposed to light moisture. However, please note that it requires patience - this isn’t an instant glue, and proper curing time is essential for maximum strength. One of the biggest strengths of this product is its balance between strength and usability. It’s strong enough for semi-permanent repairs but not so aggressive that it’s impossible to work with. The glue remains slightly repositionable for a short time after application, which is helpful when aligning screens or components. That said, it can get messy if overapplied, and like many industrial adhesives, it has a noticeable chemical odor, so using it in a well-ventilated space is recommended. On the downside, this adhesive may not be ideal for users expecting factory-level waterproof sealing in electronics. While it is water-resistant, it doesn’t fully restore original device waterproofing once a device has been opened. That's the only reason I have it 4 stars instead of 5. Additionally, cleanup can be tricky—once cured, the glue is difficult to remove, so precision during application is key. Beginners may need a bit of practice to avoid excess seepage around edges. Overall, the ALECPEA T-7000 adhesive is a reliable and cost-effective solution for DIY repairs and craft projects. Its precision tip, strong yet flexible bond, and multi-surface compatibility make it especially valuable for electronics repair enthusiasts. While it requires careful handling and curing time, it delivers solid, professional-looking results when used correctly, making it a worthwhile addition to any repair toolkit.

We purchased and used this to fix a cell phone. Its back cover would no longer stay on. I carefully removed any remaining residue to start with a clean application. The needle point tip of this adhesives applicator was perfect. It does take a bit of cautious force and a steady hand. Once applied and i allowed it to sit for 24 hrs, the phone was perfectly held together. Works as it should. Definitely will use this product again.

I used it to glue some LED’s in an RC bulldozer. I wanted a black glue. I really liked the applicator on the tubes. It seems to work as intended. Thin enough to get into tiny spots but not super runny. No issues with it, so far…

Great glue. I used it to reglue some PCB pressure switches (ice/water) to their plastic mounts on a refrigerator. Factory glue was brittle and failed and not really suited to purpose. This glue retains some elasticity so it handles the usage stress much better. Time will tell, but I tested it after 48 hours and it seems like a solid bond. Bottom line, I am happy with the results and I would buy it again.

Sticky black glue to seal the edges of the device. Needle application accuracy.

Great quality glue easy to use though you need to be precise. It sets quit quickly so you need to plan the work well. Purchased to reattach the display on my Huawei Watch 3 I have had some years after replacing the battery and noticing the display had started to come loose. I small price to keep this excellent watch working.

Bought to repair black plastic bumper & it performed well. You don't need a lot of it & make sure you have a damp cloth to immediately wipe off any excess as it dries/adheres quickly. Overall I recommend both product & seller.

Mended my 40 year old broken speaker cones with this glue and new rubber cone outer mounts. They stuck rubber to the inner paper cone well. Sound great now.

It worked fine to seal an Apple Watch screen

Great glue for speaker surround
