Measuring and mixing epoxy resins accurately and safely is an essential skill for any resin user that wants to stay healthy and have great results with their project.
In this tutorial, we will show you two recommended techniques for measuring and mixing epoxy resins by weight or volume.
For this demonstration, we are using our Super SAP CLR epoxy resin system from Entropy Resins. All of their retail formulas are two-part epoxy systems made up of a resin (Part A) and a hardener (Part B).
As with all epoxy resins, our systems are designed to work in a specific mix ratio between the two parts. Our CLR epoxy resin with CLF Fast Hardener works in a 100:47 mix ratio by weight or a 2:1 volume ratio.
Part of beginning any project is always making sure you have the proper tools and safety equipment for using and handling epoxy resins, including the following:
Note: Adding more hardener will not kick the epoxy faster, it will cause excessive blushing and negatively affect cured strengths and curing times. Only use the manufacturer's recommended mix ratios.
Note: Make sure to double check the maximum margin of error on your system.
You can also measure your epoxy resin by volume, just make sure you have mixing cups with well-marked graduations.
Now you are ready to use your resin. Remember to check the safe use guides, safe handling information and technical data sheets that come with your epoxy system before mixing.
