Epoxy resin adhesive: Everything you need to know about it
What is epoxy resin adhesive and when is it used?
An epoxy adhesive is an adhesive that consists of two components that are mixed when used: Epoxy resin and hardener. Both substances are stored separately from each other and only mixed with each other when the 2-component epoxy resin (also: 2K epoxy resin) is to be used for adhesive purposes.
How the two components are mixed depends on the packaging unit: Small quantities are often offered in a double-chamber syringe (twin syringe). Mixing takes place automatically when the syringe is used. For larger quantities you have to the two components mixed in a ratio of 1: 1 become. It is essential to adhere to the exact mixing ratio here, otherwise the epoxy resin adhesive will not harden properly and the strength of the adhesive connection cannot be guaranteed.
After mixing, the two substances react with each other and the epoxy adhesive is created. The so-called "pot life" followsduring which the objects to be glued can still be corrected. The length of the pot life depends on the processing temperature, the size of the area to be bonded and the epoxy resin used. It can last anywhere from a few minutes to an hour. Then let the worked area rest for several hours so that the adhesive bond can cure completely for the highest loads.
Since epoxy resin adhesive is versatile and extremely resilient, this adhesive is very suitable for use in repairs in the house and garden as well as in hobby and DIY projects. It can also be used as a filling material for cracks and holes in renovations: after hardening, it can be sanded, painted over and drilled. The 2-component epoxy resin has that advantage over normal superglue.
Instructions for use for epoxy resin adhesives
- Preparation: Roughen the surface a little with sandpaper. The surfaces to be glued must then be dry and free of dust, oil and grease.
- Activation of the syringe: Break off the tip of the twin syringe and screw on the practical mixer attachment supplied in its place. Hold the syringe up and carefully push the substances up to remove any air bubbles.
- Dosing and processing with a syringe: By pressing on the plunger of the syringe, you dose the desired amount of adhesive through the mixer syringe onto the two adhesive surfaces. Thanks to the practical mixer attachment, epoxy resin and hardener are mixed directly in the correct ratio. Join the surfaces to be glued together and, if necessary, fix them with adhesive tape, a clamp or something similar.
- Cleaning the syringe: After use, pull the flask back in slightly, turn off the mixer and dispose of it. Immediately remove excess adhesive from the syringe with a sharp object, clean the syringe tip with a little water and close the cap again immediately after use.
- Dosing and processing without a syringe: Dose exactly the same amount of both substances into the supplied mixing tub or - if your product does not come with a mixing tub - use a clean glass plate or a disposable container (for example a cleaned yoghurt pot) for mixing. Mix the epoxy resin and hardener thoroughly within 1 to 2 minutes using the spatula provided. Then apply it thinly to the two parts to be glued and fix them with adhesive tape or lever clamps, for example.
- Cleaning (when used without a syringe): Reseal both containers immediately after use. Adhesive residues can easily be removed from the mixing tub after hardening with a spatula.
Note: The processing and curing times vary with the different products. Therefore, please read the instructions for use enclosed with the product carefully before use.
