Dispensing, Measuring & Mixing

Epoxy Resin and Hardener

Careful measuring and thorough mixing of epoxy resin and hardener are essential for epoxy to cure properly. Check the hardener label or the technical data sheet for the correct mix ratio of resin to hardener. Whether you’re applying the epoxy mixture to wet out fiberglass, as a coating or a casting, the following steps will ensure a controlled and thorough chemical transition to a high-strength epoxy solid.

If this is your first time using an Entropy Resins epoxy product, begin with a small test batch to get a feel for the mixing and curing process before applying epoxy to your project. This way, you’ll get a good understanding of the epoxy’s open (or workable) time for the temperature you’re working in, and ensure that you’re properly metering the resin and hardener ratio. Mix small batches until you’re confident of the mixture’s handling characteristics, and because epoxy kicks off faster in larger, contained batches. It’s also a good idea to review epoxy safety protocols.

Dispensing Resin and hardener

Dispense the correct proportions of resin and hardener into a clean plastic, metal, or wax-free paper container.  Don’t use glass or foam containers because of the danger of exothermic heat buildup. Do not attempt to adjust the epoxy cure time by altering the mix ratio. An accurate ratio is essential for epoxy to fully cure and develop its physical properties.

Dispensing with Pumps

Resin and hardener dispensed at the wrong ratio is the source of most cure-related problems. To simplify dispensing and reduce the possibility of errors, use Entropy Pumps to meter the correct ratio of resin to hardener.

Pump two full pump strokes of resin for each full pump stroke of hardener. Depress each pump head fully and allow the head to rise completely back to the top before beginning the next stroke. Partial strokes will give the wrong ratio. Read the pump instructions before using the pumps.

Before you use the first pump-dispensed mixture on a project, verify the pumps are delivering the correct ratio by following the calibration process on the pump instructions. Recheck the ratio anytime you experience problems with curing.

Measuring by Weight or Volume

When not using pumps, you’ll need to measure Entropy resins and hardeners by weight or volume to achieve the correct ratio of 2-parts resin to 1-part hardener.

Volume

To achieve the correct 2:1 mix ratio by volume, simply measure out 2 parts resin to 1 part hardener before mixing the components.

Weight

The exact weight measurement for these ratios is slightly different from the volume ratio due to resin and hardener density. See the hardener label or technical data sheet for the weight ratio of the resin and hardener combination you’re working with, and use a scale to measure the desired weight. Datasheets can be found in the “PDF” tab on each product’s description page on this website.

Mixing Resin and Hardener

Using a stir stick, blend properly metered resin and hardener for at least one full minute. Be sure to scrape the sides of the mixing container.

Epoxy Cure Stages

Mixing epoxy resin with a hardener begins a chemical reaction that transforms the combined liquid ingredients into a solid. This period of transformation is the cure time. As it cures, epoxy passes from the liquid state, through a gel state, before it reaches a solid-state .
