When the center of the pour no longer absorbs the shrink, a crack develops. What’s the worst-case scenario? (I always loved those survival books.) While a little bit of shrinkage is normal, excessively hot resin cools and shrinks a lot. So why does this matter?Īs the mixture heats, then cools, it shrinks towards the center of the resin pour. A larger, thicker mass of resin is going to get hotter and take longer to cool than a thinner, smaller mass of resin. As more crosslinking occurs, more heat is produced, adding to the heat of the mass of resin. The thicker and larger the area of resin poured, the hotter the mixture gets. And unfortunately, that isn’t always a good thing. When you are pouring resin in thick layers, as you do for making the epoxy table, there can be a lot of heat. But how does this help me make an epoxy river table?Īh, resin padawan. Gee Katherine, thanks for the chemistry lesson. Feeling your resin get hot is a good thing. This crosslinking produces heat and eventually creates a solid mass of resin. The parts of each merge to start a chemical reaction, which crosslinks all the molecules. (That’s why using one manufacturer’s resin with another manufacturer’s hardener can be a reason why your resin doesn’t cure.)īy themselves, the resin and hardener don’t do much, but the magic happens when you combine them. It is specifically formulated to link with that epoxy. It has long chains of molecules that contain several elements. Okay, we’re only going to back to high school for 30 seconds. How do you do that? Let’s start with resin chemistry. Yes, We’re manipulating the resin to get what WE want. IF…Ĭrafters and artists work within the confines and the limits of the resin to get the results we want. It kinda cool to think you might have a chance in the resin fight club. When it comes to using epoxy to make a resin table, there is a cardinal rule you have to follow.
