How to wash epoxy

Epoxy adhesives are widely used for joining various parts and materials. Not always do the craftsmen manage to do the work accurately, so the question of how to wash the epoxy resin always remains relevant.

What you need to know about epoxy resin?

Such adhesive solutions are based on 2 components. Under certain conditions - the addition of plasticizer and heat treatment, they react, due to which polymerization occurs. The special popularity of such compositions is due to the fact that in the frozen form the glue is very strong, resistant to moisture and mechanical stress, and also does not lose its characteristics for a long time.

Important! This substance is used not only as an adhesive, but also for impregnation of wood, glass and fiberglass to increase their physicochemical properties and reduce the risk of destruction.

How to choose a method for removing epoxy?

How to remove or remove epoxy uncured resin? Since the application technology involves preheating the substance and applying it in liquid form to the desired surface, it is not always possible to do this very carefully and clearly along the border.

Despite the excellent characteristics, it is still possible to wash the epoxy resin, and several means are suitable for this. The basic principle is to start the reverse process, and this can damage the main surface. That is why, before choosing a tool for removing epoxy glue, specify whether it can be used with the main material, preventing its destruction.

How to rinse off epoxy resin?

To wash the epoxy resin, several methods are used:

  1. Conventional scraping with a sharp object - suitable only for those surfaces on which this process will not affect the destruction. For example, for metal this option is categorically not suitable, as well as for painted surfaces. In this case, the formation of chips and scratches is likely, which will later corrode.
  2. Warming up the cured glue. This method implies the presence of certain skills in working with construction equipment and requires maximum accuracy. An excellent solution would be such a treatment of plastic and wooden unpainted surfaces.
  3. The use of liquid solvents that will reduce the density of the polymerized coating and make it viscous, suitable for removal. Be careful here, as not every product is suitable for a certain material.

How to remove epoxy resin - method 1

To mechanically clean the surface of the hardened mortar, do the following:

  1. Take any object with a sharp flat work surface - a metal spatula or a knife. Make your choice taking into account the cultivated area.
  2. With gentle movements, gradually scrape off small layers of glue.
  3. Perform this action very carefully when you get as close to the base as possible.

Important! Be patient, as this procedure is very laborious and will require a lot of time.

How to clean epoxy - method 2

To heat-treat the adhesive and bring it to the desired temperature, use a soldering iron or a building hair dryer. Do the work like this:

  1. Degrease the surface with white spirit.
  2. Turn on the tool and heat the hardened mass to a temperature of 100-200C.
  3. As soon as the mixture becomes viscous and fluid, add a little acetone to the composition to facilitate the cleaning process.
  4. Carefully remove it with a knife or any other suitable tool if there is a large volume of “excess" resin.
  5. Clean with cotton wool with acetone if the amount of epoxy glue is small.

Important! Do not boil mass, and consider the fairly fast time of subsequent hardening. Follow up cleaning up in small sections, heating them in sequence.

How to wash off epoxy resin - method 3

Washing off of epoxy resin or glue takes place using different solvents. For this purpose, use the following tools:

  • 5% solvent for varnishes;
  • volatile solvent;
  • acetone;
  • denatured alcohol;
  • concentrated sulfuric acid;
  • tetrafluoroboric acid;
  • super acid.

The most popular ready-made solvents for washing off epoxy glue:

  • Flushing SP-6;
  • DMSO;
  • DMF.

Important! These options are so effective that they allow you to quickly rinse off the resin with relative care in relation to the basic material of the subject itself.
