Chemical Weld Acrylic with DIY Cement
- Cement for “gluing” acrylic can be easily made for next to nothing out of scraps. The bonding is fast and very strong.
- All you need are acrylic scraps, and acetone.
- The acrylic is broken up into tiny pieces that fit into the syringe.
- Acetone is added to dissolve the acrylic, turning the mixture into a very thick goop. The air bubble in the above picture took about a minute to go from the bottom of the syringe to the top.
- Place a little dab on the acrylic you wish to join. It sets very fast and doesn’t run. If you need more working time, dilute the mixture with more acetone.
- The cement dissolves the acrylic, welding the two pieces together. The acrylic suspended in the mixture hardens when the acetone evaporates leaving a nice fillet.
- Even edge joins like this are very tough. I couldn’t break these apart without tools. These samples (and ready to use cement) are on the soldering bench shelf above the monitor — check them out!
