Last two days I spent in the land of plastic 😛 Recently some people asked me about casts, silicones, resins, so I thought I would share my insights. You can read the first part here and the second part on my FB -> fb.com/kazooartdolls - there you will find even more information!
1️⃣First: I've been making casts for two years, and I don’t have a vacuum chamber for degassing the resin.
2️⃣I use Smooth-Cast polyurethane resin from Smooth-On for casting because it is super-light, matt after solidifying and quickly solidifies (in a few minutes), which for me is an advantage, because I can do slush casts (cast head empty in the middle).
3️⃣Smooth-Cast containers have a very wide neck, from which it is uncomfortable and imprecise to pour. I recommend you don’t remove metal foil from the neck, just make a bigger and smaller hole, like in a condensed milk tin, and pour through a hole.
4️⃣Smooth-On warns on the packaging to use the resin ASAP after the first opening. Calmly! While we keep the containers in a dry place, at room temperature, strongly twisted, we can easily use it again after a few months. The most important thing is to close the containers quickly so that they don’t catch moisture from the air.
5️⃣Smooth-Cast advertises itself as a resin that doesn’t need a vacuum chamber, because - colloquially speaking - bubbles are not made in it. This is not true. SC is gassing like all other resins, maybe a bit less. It is really trouble-free only when casting bas-reliefs. However, in my experience I know that you can avoid bubbles without having a pump, you just need to know how. ➡️Do you want to know more? I invite you to my FB 🤗
