| − | This comic refers to {{w|Epoxy | + | This comic refers to {{w|Epoxy}} — substances used as adhesives, sealants, and coatings, named for a particular {{w|Epoxide|chemical substructure}} that's key to these substances turning from liquids to solids. Many types of epoxy are multi-part, usually two, where the components, such as resin and a hardener, are stored separately. For ease of use, this can be in parallel syringes (of equal volume, or proportionately different widths to maintain the correct mixing ratio) such that the user simultaneously squeezes out the separate chemicals by depressing both syringes at once, onto the initial surface or into a container. The user then thoroughly mixes the components, as quickly as possible. The mixture is spread evenly (or as necessary) over the surface(s) to be joined or protected, and if there are multiple parts they are quickly positioned. The combined epoxy quickly cures, usually within a few minutes. This comic presents a fictitious 16-part epoxy, with the same apparent logic of parallel deposition in mind, with many components that are implausible or make fun of common problems people have when using epoxy in real life. |
The title text references how not all epoxies and glues work on every material, and that applying them on some can require special techniques or products. Some industrial or industrial-grade adhesives contain solvents (e.g. {{w|tetrachloroethylene}}, which is used in E6000 glue) that release harmful vapors as they cure. If used improperly, this can result in the release of chemical vapors in an enclosed space along other dangerous side-effects, while also not working as a glue as intended. | The title text references how not all epoxies and glues work on every material, and that applying them on some can require special techniques or products.

Rosin (a kind of '{{w|Flux (metallurgy)|flux}}') is one of two parts that make up rosin-core solder, used in electronic work, where the rosin is located in the center (the "core") of the solder. When heated hot enough to melt, it {{w|Soldering#Flux|cleans corrosion and oxides from the surfaces}} of the metal parts to be joined, creating bare metal surfaces that can be 'wet' by the solder. In rosin-core solder, the two substances are touching rather than kept completely separate, since they're both in solid form, and don't react with each other even when they're heated to melt them. In this respect they differ from common combination epoxy chemicals that will be both liquids that cure together on contact even at room temperature. Rosin is also frequently applied to the bows of string instruments like violins or cellos to improve the sound, as immortalized in the famous song "The Devil Went Down to Georgia". |
