Resin is a highly versatile and durable substance that is widely used in crafts, modeling and 3D printing. If you’re working on a crafts project that involves gluing resin pieces together, it’s important to choose a compatible adhesive. The two most common adhesives for gluing resin are super glue and epoxy. Each have advantages and best uses, so we will cover the details below.
Super glue is a great choice because of its ease of use and fast drying time. It’s ideal for very precise application since only a drop is needed in most cases. Be sure to read the label and choose a super glue that is compatible with the material you are using since there are many different formulas.
For precision work, you’ll love LePage Super Glue Gel Control. It holds stronger and dries faster than many similar adhesives, thanks to a patented additive. The easy-to-use gel formula virtually eliminates drips and runs and can even be used on vertical surfaces. It dries clear and is resistant to moisture and freezing temperatures. Perfect for model making!
Wondering how to glue resin 3D prints together? Epoxy is best for applications requiring extra strength. It is a two-part adhesive that will set within a limited time once the resin and hardener are mixed. You can choose from very quick-acting epoxies that set in minutes to slower formulas that have a longer working time. In either case, the result will be a very durable and hard substance that creates a powerful bond.
For gluing larger resin parts, LePage Gel Epoxy is an excellent choice. Just dispense the materials from the dual syringe, mix, and apply. A tough, rigid bond will begin to form in just 6 minutes. It won’t shrink and can be sanded, drilled, and painted once set.
Noticed any visible gaps or uneven surfaces after gluing your resin pieces together? Simply use modelling putty to fill them in. Then prime and paint your resin model – and done!
Let’s now cover how to use each of the above adhesives for gluing resin.
- Prepare the surfaces. Ensure they are clean and dry. Lightly sand very smooth or shiny surfaces with fine-grit sandpaper to improve adhesion.
- Pre-fit the pieces before gluing. File any rough edges to ensure a tight fit.
- Apply a small amount of super glue to one surface.
- Press the parts together and keep them in contact until a bond forms.
- Allow the item to fully dry.
- Clean up any drips immediately with a damp cloth.
If using epoxy, follow steps 1–2 above, then proceed as follows:
- Open the epoxy. Remove the cap, cut the tips of the double syringe, and turn the syringe to point upwards. Expel any air bubbles that rise to the top.
- Mix the epoxy. Dispense equal parts of the resin and hardener on a piece of cardboard. Mix thoroughly for about 1 minute using a plastic putty knife or similar tool.
- Clean the syringe tips and replace the caps.
- Apply the epoxy. Apply a small amount of the epoxy to both surfaces using the putty knife. Press the surfaces together immediately and hold until a bond forms. Use tape or a clamp if needed to hold the parts in place.
- Remove any excess adhesive. Use a damp cloth to remove wet epoxy. Dried epoxy can be sanded or carefully cut away with a blade.
- Allow the epoxy to cure. Most epoxy begins to set in a few minutes, full curing takes 24 hours.
Both super glue and epoxy are powerful adhesives. Avoid getting them on your skin. Always work safely by wearing nitrile gloves and safety glasses. Also, choose a well-ventilated workspace with adequate lighting.
