 ====== Solvent Cement ======
-Solvent cement is technically not an adhesive in the traditional sense — it does not “stick” two surfaces with a separate binder. Instead, it chemically softens or dissolves the polymer surface, and the pieces fuse as the solvent evaporates. However, this applies only to thermoplastics that are soluble in the solvent used. \\

-Be cautious, most fumes of solvents are nasty for your lungs. All solvents listed are flammable and toxic; use in ventilated areas only with PPE (personal protective equipment: gloves, goggles, respirator). \\
 A famous example of such is Revell Plastic Glue, but it can be had cheaper and for different plastic types too. \\

 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 ======
+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! \\
-   * There is a solvent-free version which needs pressure to fixate. Generally, Pattex is awesome for flexible materials, as it will not get rigid. \\
+      * 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. \\
