Silver painting - why is it so popular?
The use of silver paint is quite wide, ranging from household purposes to industrial ones. Due to its properties, not only protective, but also decorative, it covers individual parts of mechanisms, pipes and even bridges. And not necessarily it will be a metal surface, successfully painted and wood. And meanwhile includes silver powder and varnish, sometimes some pigments are added.
What makes it so popular? Serebryanka, whose composition is very simple, has a number of positive properties of , which are not yet implemented so successfully in other paint materials:
- layer is uniform, smooth, without divorce, and the film is thin enough but does not exfoliate;
- long service life( up to 7 years in the air, up to 3 years in the water);
- a beautiful decorative surface( with the addition of pigments, not only the silver color is possible);
- excellent corrosion resistance;
- quick drying.
Silverstone also has some
lacks of , though not affecting the properties of the coating. It is fire hazardous, and with the probability of an explosion, so it is stored away from any sources of fire and in a tightly closed container.And, of course, safety. It is desirable to observe minimum protective measures when working with paint, protect the respiratory tract and skin, and the room where the work is done should be well ventilated, and it is better to paint at all on the street.
How to breed silver alone?
Before describing the process, it should be mentioned that there are two types of silver powder: PAP-1 and PAP-2 .They differ in the technology of cooking. Moreover, it is possible to dilute the powder not only with varnish, but also with drying oil , necessarily synthetic. The main difference for both compositions is the proportions, so we'll figure out how to dilute silver.
PAP-1 is bred with a special lacquer - BT-577, in a ratio of 2: 5( 2 parts of powder for 5 lacquers).This paint can withstand temperatures up to 400 degrees Celsius and does not burn out. The first powder is poured, then the lacquer is poured in portions with thorough mixing of the whole mixture, it is desirable to use a mixer for this.
PAP-2 can be diluted with any lacquer, 1: 3 or 1: 4 proportions( 1 part of powder for 3 or 4 parts of lacquer).Prepare the paint also, carefully mixing. When you connect the components, you will find that a very thick mass has turned out, therefore, it is irrational to use it. So look at how to make silver a more liquid.
Further in both cases the paint should be brought to the paint consistency, and the degree of fluidity from the method of its application( spray, brush or roller) depends. To dilute the paint used a mixture of solvents or any one, use should be turpentine, white spirit, solvent. For the sprayer, paint and solvent( or mixture) should be mixed in a ratio of 1: 1, for the brush and roller - 1: 0.5.
We have already mentioned that it is possible to dilute aluminum powder and synthetic linseed oil. The proportions will not be very different, so you can apply the same as for varnishes. Thus, you have a ready silverback, paint yourself, which can be stored for up to 6 months in this form.
Painting silver - what you need to know?
Painting is necessary only in personal protective equipment and in a well-ventilated room, this should be checked first. And now we'll look at what needs to be done to make the silver painting successful, and the coating retains its qualities for a long time.
- The surface should be well prepared. Metal is cleaned of old paint, rust, dust and dirt, degreased. The tree is crocked and sanded.
- Paint is applied in any way in several layers, after each drying is necessary. Primed surfaces require fewer layers, sometimes one is enough.
- If you still need to put silver on another coating, but not on a clean surface, then you should remember that you can not paint on nitro-enamel, NBH and oil paints.
