How To Mix.epoxy Hardener For Rubber Repair

Epoxy resin comes as a two-function system: the Part A resin and the Part B hardener (also known every bit a goad). Knowing how to measure and mix epoxy resin and hardener is important to make certain your resin cures equally expected! Here are the steps to make sure you have resin curing success every time.

Stride 1

Clearly understand the mixing directions of the epoxy resin you are using. Not all resins mix the same!

It's important to notation several things when mixing epoxy resin and hardener:

*Does information technology mix equal parts A and B or does information technology mix two parts A to one Part B (or perhaps even something else)?
*Does it mix by weight, volume, or either?
*What are the minimum and maximum mixing amounts of the resin?

These resin mixing instructions are important to make sure y'all become the resin curing results you want.

For example, allow's say you are working with a resin mold that needs one 1/2 ounces of resin and you are using the Resin Obsession super clear resin. This resin mixes two parts A to 1 function B by volume, so you volition need 1 ounce of Role A and one/2 ounce of Part B.

Step iv

At present it's time to pour your resin and hardener into separate cups. Mensurate exactly and resist the urge to add extra hardener. Doing this makes your resin heat up too quickly and shortens the pot time of your resin.

Pro tip: Why utilize separate cups for the 2 components? In case I overpour either the epoxy resin or the hardener, I can pour it back into its respective bottle and not waste information technology.

My other pro tip: Cascade from 1 bottle, then epitomize before pouring from the other bottle. If you uncap both bottles at once, you take chances switching the lids. You don't want to cure your bottles of epoxy resin and hardener shut.

Step 5

Pour the two parts together and stir well. Scrape the sides of the cups and your resin stirring stick several times during the process.

Y'all volition likely notice your resin having a wavy appearance when first mixing the two parts. This is normal. The mix should go clear when you are done combining.

Here's an example:

This is what the Resin Obsession super clear resin looks like after mixing the resin and hardener for about 15 seconds.

This is what information technology looks like later stirring for two and a half minutes.

Pro tip: My rule is to mix the resin for ten percent of the resin's pot time. If I'm working with a resin with a thirty-minute pot time, that means I will mix the resin and hardener together for three minutes.

If you lot like to reuse your resin supplies, then you will beloved that you can make clean your resin mixing cups for another use. Here's how:

Annotation: While it's ever best to stir your resin in a style to prevent bubbles, sometimes information technology is unavoidable, especially if mixing large volumes. Information technology is always better to thoroughly mix your resin and remove bubbles subsequently with a rut gun rather than undermixing to avoid bubbles. Undermixed resin will not cure.

Now you are ready to use your resin!

Cast as desired and wait for your crawly resin projection to come to life!

And one more than pro tip: Once yous start this process, set a timer. It is a smashing reminder to focus on what you lot are doing and not lose runway of time. You lot desire to become all your resin used before it starts to cure!
