If you want to glue acrylic sheet or Perspex, then there are two things you have to take into account: ordinary glue does not work, and the bond is very tight. Gluing these plastics does not have to be a problem if you follow the tips and tricks in this blog. With a good acrylate glue and the right preparation, you can glue acrylic sheets to form a very strong structure.
Acrylate is the official name for the plastic that is sometimes known as acrylic sheet. In contrast to wood and paper, you cannot glue acrylate with regular glue as the bond with the material is simply insufficient. Acrylic must be glued with a special acrylic adhesive, we recommend Acrifix for this. Acrifix, like all acrylate adhesives, has no adhesive force, but it ensures that the contact surfaces soften and merge together. In fact, gluing acrylic is more like welding than regular gluing. Another feature of Acrifix is the fluidity, the adhesive is as thin as water. It can not fill in any unevenness in the contact surface (e.g. a cut), as regular glue does. In addition, Acrifix must be applied with a thin needle between the contact surfaces. It seems complicated, but with the right preparation, it is as simple as normal gluing.
Firstly, the surfaces of both plates must be as flat and as smooth as possible. If you order sheet material at Plasticsheetshop.co.uk, all cutting edges are finished flat but we still recommend sanding the edges. If you have cut it yourself, you can also finish it with sandpaper. We advise you to start with a coarse grit and then work up slowly to a fine grit (400 grit). Make sure that the edge is as flat and straight as possible:
Next, the parts to be bonded must be cleaned, this can best be done with anti-static cleaner or alcohol, and you can then wipe the parts dry with a lint-free (anti-static) cloth. The acrylic pieces can then be positioned on (or against) each other, use a square hook when positioning them at an angle connection. Make sure that the parts are fixed and remain so during gluing:
When using Acrifix, it is important that you wear rubber or vinyl gloves and safety goggles. Acrifix must be applied by means of a vial with a needle, this allows the adhesive to be applied very accurately. Fill the vial and screw the cap with the needle onto the vial. Squeeze the air out of the bottle and keep it squeezed when you turn the bottle over. This prevents the thin glue from dripping out of the needle, by letting go of the vial slightly the glue remains in the vial. Should this happen anyway, do not wipe the drops away, but let them evaporate. Otherwise, clouding on the acrylate may occur.
Apply the acrylic glue gradually between the contact surfaces; because of the capillary action, the glue flows between the two plate parts.
Make sure that glue flows between the parts over the entire length. After 5 minutes, the acrylic is glued, keep the two parts fixed for at least 15 minutes so that the Acrifix is completely dissolved. After 24 to 48 hours, the connection achieves its full strength.
