The base dyes seem easy to use, can be used for hand painting and result in particularly bright colors, which are quite woolly in acrylic. They are certainly not for beginner use, nor for the use of many experts. See my page, About basic dyes, for more information on using basic dyes to dye acrylic. Mix the liquid stain for more functions according to the bottle instructions or pour directly into your plastic dye containers for deeper colors.
Also make sure to clean your parts very well for your dye bath. While these dyes can only produce light dyes or, at best, lamina media or acrylic block, the use of liquid-strugged dyes is the easiest and safest method for beginners. The dyeing process generally takes about minutes, but depending on the type of plastic, it can take up to an hour. If something is not painted even after an hour, chances are you will not take the dye properly.
Thermoset green, for example, can differ from phenol green, without any other noticeable difference in appearance, so it slightly increases our available color range. In the worst case, where a customer absolutely needs a very specific color, we can turn to an excellent local spray painter to color the ball in any RAL or Pantone color. While wearing rubber gloves, add the synthetic dye to the water according to the product instructions. Cook the mixture for a few minutes until the dye is completely dissolved and mixed. While boiling water, fill a second container or pot with cold water to rinse your object. Place this container next to the pot where you are painting your object.
Take, for example, a piece of plastic for building blocks that I soaked for a few days in a mixture of Ride and acetone paint. The plastic changed very slightly in tone, but it is clearly not black as intended. However, the story is different with transparent colored acrylic balls.
Place the object on a protected and waterproof surface to dry in the air. Make sure that this area is protected from other objects, people or animals that may encounter the object while it dries. If you use a dispersed dye, you can pour the mixture into a bath drain. Beware of the arms only on the porcelain surface, which will be washed more easily.
Until about eight years ago, we were able to easily paint transparent acrylic balls with Ride fabric dyes: you put the dye in the water, boil it and add the clear acrylic ball. Half an hour later the ball was colored and if the customer wanted to make a model made with one or a hundred turquoise acrylic balls, we could make them in a batch and make up the model. And then, I think, Rit changed his dye formulations that wouldn’t confirm color on acrylic; At first I blamed the new batch balls, but when I tried older stocks they couldn’t paint them either. Every dye I tried didn’t work: in recent years I’ve tried almost every available dye with virtually no success. Some dyes gave a light shade, but nothing like the rich colors we needed. Then I remembered that a) a chemical b) a physical chemical yc) had given an extensive lecture course on the physical properties of polymers.
For some spray paint, you don’t need to prime and seal the paint. Spray paint also tends to dry faster than liquid handmade paint, making the process very simple. Some acrylic paint can also be supplied with primer or sealant already in the paint. Others require you to prepare the surface and seal clear acrylic sheet the paint for best results. Acrylic plastic refers to a family of synthetic or artificial plastic materials containing one or more acrylic acid derivatives. The most common acrylic plastic is polymethyl methacrylate, which is sold under the brand names plexiglass, lucite, perspex and crystallite.
