Tabletop Pro by Weight. 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. With its long pot life of 45 minutes, this gives you plenty of working time. Next, the Part B is added using the same weighing procedure. If more is required to complete the job mix up a batch of 1.5 (minimum recommended mixture). Keep in mind the mix ratio by volume and weight are VERY DIFFERENT. 5:1 Total Volume. Mixing When hand mixing the epoxy resins and the hardeners, it is best to pour the resin, the Part A, into the mixing vessel first. In this case, we’ll use 6 ounces of epoxy and 3 ounces of hardener, measured by volume, for a total of 9 ounces of mixed material. Many repeat epoxy users measure by weight instead of volume so they can use any container as long as they have a scale on hand. All of their retail formulas are two-part epoxy systems made up of a resin (Part A) and a hardener (Part B). They are used to tint epoxy resins used as coatings, paints, gelcoats, laminating, casting or self-leveling resins. Double check the volume mix ratio of your product and enter the total volume you need to find out how much resin and hardener you’ll measure. In this tutorial, we will show you two recommended techniques for measuring and mixing epoxy resins by weight or volume. Many users find working with a 1:1 by volume the easiest. This is useful for very small or large projects where you can’t use our cups. Determine as close as possible the amount of mixed material that the application requires. For deeper pours make sure you’re using a product designed for that application like our. Mixing Epoxy Resins After the two parts are poured at the correct ratio, mix them together thoroughly for a full 2 - 3 minutes with a mixing stick, mix longer for larger quantities. If you require more epoxy resin, you can always mix a second batch to finish off the job. If your scale resets due to inactivity before you have a chance to complete the mixture you’ll only need to measure out the hardener. Varied ratios like 2:1 and 3:1 require graduated mixing containers to ensure accurately measured material. This will ensure that all the hardener is thoroughly mixed with the epoxy and should prevent the resin from having an improper cure. Make sure you have the right pump for the container – these are 301A for the A pack size (1kg of WEST SYSTEM 105 epoxy resin with 0.2kg of 205 Fast or 206 Slow hardener) and 301B for the B pack size (5kg of 105 epoxy resin with 1kg of 205 Fast or 206 Slow hardener). Not all resins mix the same! Consult the instructions for the ratio needed. It depends on the depth of color you want. A vast majority of available coating epoxies utilize a 1:1 by volume mixture.

Also the correct additions should be observed to maintain good results. If something changes in the composition between resin and hardener, unforeseen problems can occur. Pumps make measuring the correct ratios of resin to hardener very easy. Additions outside these bands in not advisable for proper curing, in fact adding more than 4% may result in a failure to cure. Epoxy resins can be measured by weight, but due to the nature of specific gravity of the resin it is important to follow the ratio guide, and the use of electronic scales is essential.
