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.
This resin uses a 3:1 hardener. Mixing 3 parts epoxy to 1 part hardener will give you the appropriate final mixture.
Proceed to then pour in the Resin, using the general rule of thumb of two parts epoxy to one-part hardener. That said, this is not always the required ratio. Before mixing, be sure to review directions from the manufacturer for the specific materials you're using.
Mix the desired quantity of Base & hardener (Mixing Ratio is 3 : 1 Base to Hardener by volume). After mixing these two components in proper ratio stir well & allow this mixture to remain in stand still for 5 – 10 minutes. Use thinner EP-102 for adjusting viscosity of the mixture suitable for spraying.
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.
A mixing ratio of 50:1 (50 parts filler to 1 part hardener) must be strictly used. 6. Mix all the filler and hardener for approximately 2 minutes, by incorporating all the hardener into the filler so that the mixed colour is uniform. BE SURE NOT TO MIX IN AIR.
In a 1:1 ratio epoxy, you need 1 part of Part A (the resin) and one part of Part B (the hardener). In a 2:1 ratio, you need 2 parts of Part A and one part of Part B. Now that you know what the numbers in the ratio mean, let's look at how to measure the right amount of each part.
Your resin's pot time is reduced.
When using too much hardener, the mixture heats up too quickly and may flash cure before you ever get a chance to use it.
If you add too much hardener to an epoxy resin system, it will decelerate the curing process, leading to an improperly hardened and non-functioning product. This makes it crucial to have the right ratio of resin to hardener if you want to create an epoxy system that truly works.
Adding too Much or too Little Hardener
If you add too much hardener to your resin, it will cure too quickly and will be very difficult to work with. On the other hand, if you don't add enough hardener, the curing process will take much longer than usual if it cures at all.
Resin to Hardener Ratio:
Measure epoxy resin and hardener to a perfect 1:1 ratio by volume. Mix thoroughly and consistently for 3-5 minutes until there are no streaks. This ratio must be followed precisely in order for you resin piece to cure properly.
Doming - you can apply your resin right after the 5 minute rest period, or let the resin thicken for up to 25-30 minutes. Varnishing - best applied by pouring, or spreading with mixing wand, right after rest period, or up to 20 minutes after mixing.
Start by pouring 15 oz of resin into the measuring cup, followed by 15 oz of hardener, to give you 30 oz total. The 32 oz kit is the perfect amount for your project's needs.
If you by accident mixed two parts of the same components or incorrect ratio 2:2 or 2:1 – resin or hardener: resin will not cure properly. In order to harden, the chemical reaction requires EQUAL amounts!
Sticky resin is the condition that your resin didn't cure completely (gel state) and the surface is still tacky. Chances are you didn't measure your portions correctly, mix them thoroughly to create the necessary chemical reaction, or leave them in warm temperature.
Your resin may be old. Old resin kits that you've forgotten about collect moisture, especially if they haven't been stored properly. That extra moisture makes your resin cure bendy. ⭐️ BONUS: Learn how to store resin so it's at its best.
Artist Resin needs a 1:1 resin to hardener ratio. An increase in hardener will not make the curing process quicker. Instead, it will create bigger problems like an uncured resin and a sticky surface which can only be resolved by re-doing the coating.
One to One (1:1)
Part A= 100% Part B= 100% If you were ordering a pint kit, this means you would be receiving one full pint of Part A and one full pint of Part B. After mixing Part A and Part B together, you will have 2 full pints of material.
How to calculate mixing ratio? Sum all the components quantity: a+b+c = total. Divide the amount of each of them by the total: a/total, b/total, and c/total.
tube of liquid hardener (MEK Peroxide) is sufficient to harden the entire contents of a gallon container. Add 14 drops of liquid hardener per 1 oz. of Fiberglass Resin (or for ¼ can of Fiberglass Resin, use ¼ tube of liquid hardener).
For small applications use 10 drops of hardener per ounce of resin. Working time will be 10 to 12 minutes. For larger applications, use half of the fiberglass resin hardener supplied, to half of the resin container. Using large amounts at one time will cut the working time in half of the mixed resin.
The weight ratios are calculated thusly: Resin Weight = (resin ratio / (resin ratio + hardner ratio)) x desired weight.
