Epoxy Mix is a type of compound mixture that is extensively used for domestic and industrial purposes. It is not a single compound; it is a mixture of two different chemicals - resin and hardener - which when mixed together, undergo a chemical reaction to produce a polymer called epoxy. This polymer has various applications, and is used for painting, and coating in adhesive materials, industrial composites and tools, electrical systems and electronics, consumer and marine applications, aerospace, art, wind, and energy applications.

It is often recommended that epoxy should be mixed differently according to the intended purpose. Consider the following steps while mixing epoxy.

WARNING: Mixing epoxy releases fumes that can be toxic to breathe in, and it can harm your skin if you have skin problems. Read the instructions on the epoxy tube before use, put on a pair of work gloves and make sure your work area has proper ventilation before you start working. If you have a history of respiratory issues, put on a face mask before you start working.

Step 1 - Determine the Ratio of the Ingredients

Determine the ratio of the amount of resin to that of hardener required to prepare the epoxy mix. Do not use these ingredients in random ratios.

Step 2 - Prepare a Sample

Make a sample portion of epoxy by mixing the resin and hardener in small proportions. This will give you an exact idea of what the final results would be like.

Step 3 - Prepare the Final Mixture

If you feel that the end result would be satisfactory, use two containers to take required proportions of resin and hardener and pour them into an empty container (ideally, this should be made of polyethylene plastic; metal is another option. The use of glass containers is a definite no-no). Use stirrer or drill mixer to continue with the mixing process for at least three minutes.

Note that hot mixes harden very rapidly; hence, caution should be exercised while mixing.
