The market is full of different types of resin. You will find Epoxy Coating Resin, Polyester Resin, Casting Resin, and the list can be endless. Some resins need a longer time to cure, while others need low viscosity. Again, some resins can be used in a 1:1 ratio, while others require a more elaborate mixing ratio and catalyst. Pouring too much of your resin will result in yellowing or cracking. A small mistake with resin, and you will end up with a ruined project! So, it is better to have a clear idea before you set out with your little project. To be on the safe side, you can consider SquidPoxy.
But, if you want to take matters into your hands, you must know the difference between the epoxy resin and casting resin. Are you thinking if the epoxy resin is the same as casting resin? This article will walk you through all the answers you need to know if the two varieties of resin same.
Finding The Difference Between Epoxy Resin And Casting Resin:
Each type of resin has different purposes of use. Trying to differentiate between the two is not how you find your answers. It is so because both resins have their blend type and many similarities. That is why these two are sometimes used interchangeably. However, the main difference lies in what they are used for. Casting resin is used for thicker applications for molds, jewelry, while the epoxy is used for coating purposes. There are many aspects like cure time, viscosity, and many more that set these two apart. Let us take a more in-depth look into these aspects:
Cure time: Epoxy resin is faster than casting resin. Casting resin takes up to 30 to 50 minutes to cure, while epoxy needs around 10 to 25 minutes to fix.
Work time: Do not confuse it with cure time. It refers to the period before the resin starts to set up, and beyond this time, you cannot move the resin quickly. Casting resin has a much longer working time than epoxy resin. This is because casting resin has a longer cure time. Epoxy resins will set up as quickly in 20 minutes, and casting resins may net up to 18 hours to gel.
Heat: casting resin discharge heat slower than epoxy. Thus, pouring too thick a layer of epoxy could heat up, and cracks will begin to appear.
Viscosity: Casting Resin is thinner when compared to epoxy resins. Epoxy has a more runny consistency.
Mix ratio: This is a highly generalized aspect of both varieties of resin. Casting resins generally use mixing ratios as 3:1, 2:1, and 1:1. On the other hand, epoxies use a 1:1 by volume mixture. However, the mixing variation depends on the project you are working on.
Pour depth: Epoxy resin may need up to 1.8 to 1.4 inches per application, and casting resin will require more. If you pour more than the required pour depth, the accelerated reaction will begin.
Bubbles: Bubbles are fun, but not when it comes to resins. Even though both varieties of resins are vulnerable to bubbles, casting resins show lesser bubbles as it is thinner. However, with proper application, you can avoid the problem with bubbles.
Hardness: In most cases, epoxy is harder than casting resin. It is because of the varied mix ratios of casting resin.
Scratch resistance: Epoxy resin has a more superior scratch resistance to casting resins.
Does It Make A Difference?
In the previous lines, we have put the differences between casting and epoxy resin in a nutshell. Now, it is time to answer another critical question- does it make any difference? To be precise, YES, it does make a difference! Each type of resin performs specific tasks and comes with various specifications appropriate for different projects. You cannot mix and match- the result will be nothing but a disaster!
