With such a range available, each type of casting has their own merits and downsides. We'll take a look at each type below!
Polyester resins consist of a resin and a small amount of catalyst. The main downside of polyester resins is the miniscule 2% catalyst addition. This is added to cure the resin, and the small percentage can often prove difficult for users to get right. Polyesters also have a strong odour. On the other side, these resins are quite cheap, and for that reason are used by some.
