Can you mix resin in a glass cup?
Do not use glass or foam plastic containers. lf resin and hardeners are dispensed into separate measuring containers and then poured into a common mixing container, be sure to scrape all container surfaces to get all the remaining material into the mixing container to assure proper proportions.
Can I use measuring cup for resin?

Why did my resin melt my cup?
You look over and see your epoxy resin smoking or maybe your mixing cup melted. When you mix Part A (resin) and Part B (hardener) together new chemical bonds begin to form causing an epoxy exothermic reaction. Energy is released in the form of heat as the mixture catalyzes.
Can you use Styrofoam cups to mix resin?
Plastic (solo) and foam cups only work for epoxy resins, both will fail when using Poly or Vinyl esters. Some food containers will survive the esters too….
What happens if you put too much hardener in resin?
Measure ArtResin in precisely equal amounts by volume: Adding too much of either resin or hardener will alter the chemical reaction and the mixture will not cure properly.
What is best to mix resin in?
6) Mixing with improper tools – The best tool to mix epoxy is a flat bottom stick or spatula, similar to a paint stir stick. This type of tool will help you scrape the sides and the bottom of the tub easily to throughly blend the resin and hardener better than a tool like a screwdriver or chopsticks.

Why did my epoxy resin get hot?
The main reason that epoxy gets so hot is due to the exotherm during the curing process. When base epoxy resin and the hardener (curing agent) are mixed, there is a chemical reaction that causes them to heat up.
Why is my resin still sticky?
Sticky resin is typically caused by inaccurate measuring or under mixing. Sticky, tacky resin: often caused by inaccurate measuring, not mixing thoroughly or by curing in cold temperatures. Try moving your piece to a warmer spot: if it doesn’t dry, re-pour with a fresh coat of resin.

What’s the difference between casting and coating resin?
Unlike coating resins, casting resins have a thinner consistency and take a longer time to dry. Casting resin takes a longer processing time, and it can take up to one week to cure completely. Casting resin allows you to cast thicker layers as compared to epoxy resin.
Does tacky epoxy ever cure?
You cannot leave the sticky resin, as it will not harden after time, it will remain sticky. You will have to either throw your item away or fix the problem. In order to avoid the problem all together make sure to do the following: You must measure out your resin and hardener precisely.
What is the mixing ratio for resin and hardener?
Mix the resin 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.
