SCIGRIP Weld-On #4SC Adhesive, 1/4 Pint and Weld-On Applicator Bottle with Needle

So much better to work with than CA glues. This being a solvent slightly melts the plastic (similar to what acetone does to ABS) and welds the parts together for a strong permanent bond... The part itself will break before to welded joint does. This product will weld PETG and PLA parts, and mine came with a fine needle tip applicator bottle.My only complaint was how tightly the jar is sealed... You're basically going to need a pair of channel lock pliers to get it unscrewed, then once you do, there's an internal metal seal you need to pry out... This chemical is toxic, so for God's sake use in a well ventilated area and ppe.

Good quality, little slow on shipping

It really does weld Plexiglass/Lexan/Fingers together. I use this mainly to make motherboard armor and spacers, but I imagine it could be used to fasten warp core plasma injectors to the primary manifold conduit, in a pinch.

Works a expected.

Had to glue together broken fridge shelf. This did the job. Solid brand, solid product. will buy again.

The adhesive fluid is very thin, and will fog the surface of the plastic if it is spread/spilled outside of the area to be bonded.

It's easy to use, works fast, and works very well for PLA.
