 Typically composed of acrylate or methacrylate monomers and oligomers, along with photoinitiators. When exposed to UV light, the photoinitiators generate free radicals that rapidly polymerize the monomers into a solid plastic-like material forming a a strong, clear bond within seconds.
 UV glue is ideal for glass, plastics, and electronics, and is commonly used in optical and jewelry work due to its transparency and fast curing.

+Hot glue is often used in hot glue guns with different temperatures. There are all kinds of different sticks with different temps for different materials. \\

    * Think outside the box: Ski repair sticks are good for filling cracks/holes of plastics too. Just make sure you tape non-melting and non-flammable material on the other side, so the plastics will not deform! \\
-   * Pattex: There is a solvent-free version which needs pressure to fixate. Generally, Pattex is awesome for flexible materials, as it will not get rigid and stay flexible. \\
+      * flaming thermoplastics (e.g. zip ties) with a lighter for plastics repair (it gets brittle though) \\
+   * There is glue for nearly every material with different compositions:
+      * Vulcanizing glue for rubber: Commonly used on bicycle tires. Roughen the surface with sandpaper first
+      * ceramics, aka elephant glue
+      * wood glue (PVA / aliphatic resin) – hard, rigid joint
+      * fabric / textile adhesive (sticks to wood too but remains highly flexible)
+      * contact cement aka "Pattex" (stays flexible): There is a solvent-free version too which needs pressure to fixate.
+      * Silicone adhesive / sealant can be used as flexible glue and is waterproof
+      * Latex-based glue – very flexible, used for fabrics and paper crafts
+      * PU (polyurethane) glue – flexible to semi-rigid, gap-filling, moisture-curing; often used in mounting adhesive
+      * Rubber cement – flexible, peelable
+      * Acrylic polymer emulsions (PVA-like but stronger, more weather-resistant); can be painted over
 Fun Facts:
-   * Regular Pattex glue will "melt" through polystyrene/styrofoam. \\
+   * Regular Pattex glue will "melt" through styrofoam (expandable polystyrene foam (EPS)) and deform polystyrene (PS) as it contains [[life_hacks:glue#solvent_cement|solvents]] \\
    * Post-it glue was originally developed for super strong adhesive but was discovered by accident and remained unused until the invention of the sticky note. \\
