Depth staining of organic glass makes it possible to obtain an evenly durably colored surface while maintaining the texture of the material. Staining is carried out in water-alcohol solutions of disperse dyes. The process is simple, plus it allows you to get juicy shades.

Prior to painting, the surface of the products should be thoroughly cleaned, otherwise the smooth color can not be produced in any other way. The surface is wiped with a swab of soft cloth dampened in gasoline or alcohol, and dried, and immersed for 15 minutes in an aqueous solution of detergent. The temperature of the solution should be within 50-60 degrees. . Then, the product is rinsed thoroughly in cold water and also transferred to the dye solution, which is prepared as follows: mix 5-15 g of dispersed dye (in the choice of color, see Table 1 ), to form a homogeneous mass (paste), 2-3 g of neutral washing powder (for washing natural silk fabrics) also 20-30 g of alcohol (ethyl, butyl or benzyl) also add hot water to a volume equal to one liter. After thorough mixing, the solution is filtered through a double-folded kapron fabric (a kapron stocking can be used).

One of the conditions for good coloring is the protection of the solution from contamination, its continuous mixing during operation, periodic filtration with repeated use, also the addition of alcohol by the measure of the consumption of the solution. Color saturation depends not only on the temperature of the solution, but also on the duration of dyeing. To obtain an average color saturation, the dyeing time should be 15-20 minutes.

At the end of the painting, the product is rinsed thoroughly in cold water and dried.

Staining should be made in containers of materials resistant to the dye (glass, porcelain) used, otherwise the paint may not turn out to be juicy, but the dishes will be spoiled. You can similarly use enamelware.

Surface staining of the organic glass makes it possible to obtain a film containing the dye also directly connected with the surface of the organic glass, since substances that dissolve glass enter into the composition of the dyes used. The coating is durable and well polished. There are many coloring recipes, of which five are the most acceptable in amateur practice.

1-st recipe. A dye of the desired color from the set of aniline inks is dissolved in acetic acid, adding it a little bit until until the desired color shade is obtained. The solution is filtered and mixed in a volume ratio of 1: 1 with a mixture of toluene ( 70% by volume) also dichloroethane ( 30% ). The obtained mash is again filtered, and the organic glass shavings are dissolved therein in such a number that the resulting dye can be sprayed with a pulverizer. Apply the dye to the surface of the organic glass in several layers at intervals of 10-15 minutes .

2 nd recipe. 30% (by volume) of dichloroethane are mixed, 60% of benzene is also 10% of acetic acid. In this composition, dissolve the paint. The solution is also filtered by adding shavings or sawdust of organic glass. Staining is also carried out with a spray gun.

The third recipe. In 10 parts by volume of acetic essence, 1 part of the paste for ballpoint pens is dissolved. With a smaller amount of paste, the solution wets the painted surface worse. To obtain a more saturated color, the essence of the paste in the solution is increased. You can use the filled pins of ballpoint pens, cutting them into pieces with a length of 6-10 mm, plus placing them in a vial of vinegar. To accelerate the dissolution of the paste, the vial should be shaken vigorously from time to time.

The dye is applied to the glass with a soft brush with continuous non-overlapping strokes. The dye spreads well, forming a uniform layer.

4th recipe. 6 parts by volume of acetic essence dissolve 1 part of sawdust or chips of organic glass also add a paste for ballpoint pens. Apply the composition better with a spray gun.

The 5th recipe. Dissolve the required amount of paste for ballpoint pens in dichloroethane. Apply the solution to the surface of the part with the help of an atomizer, but you can also use a soft brush or a soft tissue swab.

Painted on the above recipes, the products are dried for at least 24 hours. All operations should be performed in an open atmosphere or in a fume hood. Keep cooked dyes in well-corked dishes (preferably with ground glass stopper).

The dyeing of organic glass in milk color is done by immersing it in concentrated sulfuric acid for 1-10 minutes . (Glass TOPEX brand, resistant to aggressive media, such a finish is not exposed). When exposed for 1-3 minutes, the surface of the organic glass does not lose its luster and also becomes milky. If you etch the glass further, then its surface becomes snow-white also slightly matte. With increasing pores, the effect of acid, the white layer becomes thicker. If this layer is not deep enough, the process can be repeated. After finishing in acid, the organic glass is thoroughly washed in running water and dried. Rinse carefully, as if the layer formed is soft and can easily be damaged. It should also be borne in mind that the mechanical strength of the surface layer during deep processing is also insufficient after drying. To leave on the product transparent premises, these surfaces are covered with a thin layer of wax. After washing, the wax is also removed by drying.

If it is time to increase the etching, for example, up to 20-30 minutes , then the surface will wrinkle after drying, and also assumes the appearance as if it is covered with moiré varnish. The treated organic glass can be colored using one of the recipes listed above.
