For larger areas of frosted acrylic because the glue edges will show through the frosted based on the way light refracts (for that I’d use 3M or Drytac since it covers the full surface)

If you spill this stuff on the surface DO NOT BLOT it. Let it evaporate off or it will craze/smoke/fog the surface. Although this is simple to use, if your syringe is leaky it will get everywhere. Also the fact that you need a unique tool to apply it lowers its easy of use score. If you plan to apply this to the “seam” of a smaller piece on top of a large one (not like my sample where the outer edges all meet and it can be clamped) then tape it down before flooding the joint to it doesn’t slide out of alignment. With really, really tiny pieces, for that I might still use Weldon as it won’t squish out the sides since it’s water thin – if you are careful (and use tweezers to just gently tap your pieces into the glue then you may actually have equal/better results with the All Craft) Adhesives are always stronger when applied over a greater surface area. The more surface you cover, the better your bond. Acrylic sheets are noted for their exceptional clarity and optical properties. Acrylics are widely used in lighting fixtures because they are slow-burning or even self-extinguishing. This seems to be one of the most commonly asked questions I see out there –“How do I glue acrylic to acrylic?”Its probably not the greatest material for wear resistance, so discount it for high wear applications.

Optical Clarity– For all my experiments I tried to only apply the glue completely across the surface. When I refer to clarity I’m looking for how both the glue dries, and if you can see where it “ends”. In the majority of applications, acrylic sheet will not shatter. Rather, it breaks into large dull pieces. Since acrylic is softer and more easily scratched than glass, scratch-resistant coatings are often added to sheets to protect it. While it is not particularly flexible, it’s advantage is that it can be curved and formed into a variety of shapes and configurations. Acrylic swells and dissolves in many organic solvents. Its impact strength is still significantly lower than polycarbonate and some engineered polymers. Acrylic ignites at 460 °C and burns, forming carbon dioxide, water, carbon monoxide and other compounds, including formaldehyde. Loctite G02 | Make sure you don’t use any of the other Loctites – it’s got to be the gel G02 version. So this one is actually one of my favorite adhesives because you can apply it BEFORE laser cutting. There is no spillover, it’s easy to use and apply, and it’s often used in professional sign making. I find for translucent or frosted acrylics it actually works FAR better than liquid glues which often show through (as patches which you can see above).Gorilla Glue | I’m coming around to this stuff. The fact that it peels easily from the surface after drying is great – my main concern is does that mean the bond is weaker? Time will tell. Acrylic sheet can be joined using Tensol cement or even superglue, also with heat (welding), or by using solvents such as di- or trichloromethane to dissolve the plastic at the joint, which then fuses and sets, forming an almost invisible weld This brand is FAR better than the Plastruct shown above which fogs significantly and does not evaporate off of the surface without bad marring. The fogging typically occurs because excess weld cannot evaporate out. I did not notice a lot of fogging with this brand but it does happen from time to time. This product also evaporated better and was less likely to ruin the acrylic’s shine if it got in the wrong spot. Still, you want to be precise with it. It flows FAST so use a delicate touch. Sawing works well on conventional woodworking table saws with fine “triple chip teeth” and work guided against the table saw fence or miter gauge. No melting problem. Curved shapes can be done manually with a scroll saw with the proper blade and relatively slow blade speed. Focus on strength over clarity if using opaque acrylics – if you can go with the acrylic weld, that will create the strongest bond out of all the adhesives
