Measure Resin by Weight Instead of Volume [Maker Update

Most epoxy resins instruct you to mix by volume, but you can get more accurate mixing ratios if you measure them by weight, especially if you’re mixing smaller amounts. Here’s how. Of course, the first thing you’ll need is a scale. Then, read the fine print on your resin and find it’s by-weight mixing ratio. This will usually be slightly different since the resin and hardener have different densities. Put your mixing cup on your scale and zero out the weight. Then, pour out your desired quantity of the resin. Multiply that weight by the mixing ratio and then zero out the scale again. Pour in the hardener, until you reach the correct weight.

Now you can mix the resin thoroughly, making sure to take your time to get it fully mixed, confident in the knowledge that your mixing ratios are correct. For more tips like these, check out the full episode of Maker Update, each week on the Digi-Key youtube channel.
