How to Use Bonding Acrylic Liquid?

If you want to glue acrylic glass, you need to pay attention to two things: conventional glue is ruled out, and the fit requires great accuracy. If you follow the tips and tricks in our blog, acrylic gluing will be a breeze! You’ll need the right bonding acrylic liquid and the right preparation. With these two things in tow, half the battle is already paid!

Bonding acrylic glass

Acrylic is the official name for a type of plastic, also known as Perspex® or Plexiglas®. One of the unique features of this material is that it cannot be bonded with regular adhesive. The reason is that it simply does not provide enough adhesion. For this reason, you need a special adhesive that is suitable for acrylic glass. We recommend Acrifix® for this purpose. Like all adhesives for an acrylic glass, this one does not have any adhesive power of its own. Instead, it provides soft contact surfaces that then melt together. In principle, acrylic bonding is, therefore, comparable to welding. Another positive property of Acrifix® is its thinness (flowability). As a result, it does not fill unevenness on the surface, as would occur with a saw cut, as regular glue would. Unlike the latter, Acrifix® is applied with a thin needle between the contact surfaces. This seems a bit complicated at first glance. You will find that proper preparation is just as easy as “regular” gluing.

The most important thing is that the surfaces of the two plates are as smooth and flat as possible. We already accommodate you here by delivering all panels with flat-cut edges. Nevertheless, we advise you to sand the edges again yourself. If you have made a saw cut yourself, you can also rework it with sandpaper. We recommend that you start with coarse sandpaper. Then gradually move on to finer sandpaper with 400 grit. Make sure that the edge is as straight and flat as possible.

You will then need to clean the moldings to be bonded. This is best done with alcohol or an antistatic cleaning agent. Then rub the moldings dry with an antistatic (lint-free) cloth. Now you can position the moldings on top of or against each other. In the case of a right-angled connection, use a window angle for this purpose. Make sure that the moldings remain fixed during the bonding process.

When working with Acrifix® adhesive, you will need safety glasses and vinyl or rubber gloves. Acrifix® is applied through a bottle with a needle. This makes the adhesive extremely easy to apply. Fill the bottle and screw the lid with the needle onto it. Now the air is pressed out of the flacon. When turning the bottle over afterward, it must be pinched shut. This prevents the adhesive from dripping out of the needle. To allow the adhesive to remain in the bottle, give a little with the pressure of your fingers. If some adhesive does drip out, do not wipe it away! Otherwise, you would risk clouding the acrylic glass. Instead, simply let it evaporate.

When gluing acrylic glass, apply the adhesive slowly between the contact surfaces. Capillary action will then cause it to flow between the two sheets.

Make sure the adhesive flows completely between the sheets. It will take approximately 5 minutes for the acrylic to bond. Fix the two moldings for at least 15 minutes to allow the adhesive to soak in fully. The adhesive bond takes 24 to 48 hours to reach its full strength.
