Advice 3: Where used bakelite varnish

Bakelite varnishes are solutions of resins in alcohol-based, made using the condensation of phenol and formaldehyde. The catalyst in the chemical reaction in this case is ammonia, which gives the varnish odor.
Where used bakelite varnish
Bakelite varnishes are used for coating various surfaces, their main purpose is to protect equipment from the effects of агре6ссивной industrial water, weak and strong acids. Also, these paints are used for painting gas tanks and as connecting means for laminated plastics. In contrast to many analogues, bakelite varnish may be used for impregnation and even gluing pieces of highly adhesive materials.

Manufacturer of varnish

For preparing bakelite lacquer is used of the phenol, formalin, ammonia water and ethanol. Phenol is an organic compound which is completely soluble in water and solidifies at temperatures above 40o C. formalin is a transparent liquid with a low degree of reactivity, phenol is considered a poison. The ammonia water is 20% aqueous solution of ammonia. Ethyl alcohol or ethanol is a colourless thin liquid, the product of the distillation of carbonaceous products. The result is a transparent solution that can be as red, and brown.

The shelf life of the lacquer should not exceed three months from the date of its manufacture.

Types of paint

Bakelite varnishes are of different varieties:
- Lbs-1 and lbs-2 (top grade),
- Lbs-4,
- Lbs-5,
- SBS-1,
- Lbs-8,
- Lbs-16,
- Lbs-20 lbs-29.

Depending on the brand varies with the percentage of the above substances in the resin varnish. In the result, change its properties and functions. So, for example, varnish lbs-4 is used for the production of plastics with mineral fillers and SBS-1 for the production of wood plastics and plywood.

The main task of bakelite varnish is the creation of a thin protective film, which may consist of inorganic and organic polymers. This film does not change the color of the surface, hides imperfections and prevents the penetration of moisture into the product. A feature of this Polish is the vegetable oil part of it. Also, the bakelite varnish is cellulose, which is pre-processed.
Properties of bakelite varnish will not change if you add the dye, so you can easily find the right color of nail Polish.

The use of bakelite varnish at home is complicated by the fact that after applying the Polish on clean and dry surface must be exposed to heat, gradually increasing the temperature to 160оС. In the end (after 20 seconds) will be the polymer film, which will last a long time if the ambient temperature is above 20 ° C, and also excluded a direct effect of sunlight.

Advice 4: Wood varnish for exterior use – the beauty of the material under reliable protection

Working with wood, craftsmen strive to preserve its texture. This is possible using a tool like varnish. Coatings, wood made on a different basis, so their properties as the drying period varies.
Wood, lacquered, longer retains its quality
Lucky for the tree of good that does not hide, but rather emphasize it. But this is typical only for transparent or very light compositions, colored give the tree shade. Varnishes are made of water, alcohol, polyester, acrylic, cellulosic, polyurethane, oil-based.

Some wood varnish to choose?

Varnishes for wood, water-based are odnokomnatnaya. This is the most dolgosrochnuyu compositions among all of these types of coatings for wood. They can be diluted with water, easy to apply, suitable for all types of work.

Varnishes based on polyurethane are inexpensive and dry quickly. They are both one - and two-component. Some of them require precoating of the surface. These compositions diluted with solvents, so they have quite a pungent smell. Mainly used in furniture manufacturing. Among the shortcomings of these tools of wood processing include the availability of harmful substances.

The nitro lacquer is made on the basis of cellulose. This is perhaps the most popular type of varnish, the reason for that – short drying time and low cost. But these compositions have significant disadvantages: low resistance to abrasion and UV radiation and possible delamination.
Acrylic varnishes are more expensive than their counterparts, but are often used in furniture manufacturing because of its excellent light fastness, durability, high-quality gloss. These compounds a very long time to dry, that does not prevent them to be the most popular among those who are passionate about decoupage.

Varnishes based on polyester are used quite rarely because of the complexity of application and high toxicity. They are sprayed in aerosol form, and require a special tool. These compounds are used in the manufacture of musical instruments, as they are able to create a fairly thick layer of the coating.

What a lucky tree suitable for outdoor use?

For external works use cold-resistant, light-resistant, moisture-resistant coating. Only such coatings can reliably protect the wood from rain, wind and sunlight. You cannot apply for wood which is on the street, the compositions forming the non-elastic film. These include the nitro lacquer. In addition, the varnish for exterior use should contain anti-bacterial additives that protect wood from insects and prevent rot.

For outdoor work you can use varnish on acrylic, oil, water-based. Most worthy among these coatings consider high strength yacht varnish. The most popular formulations for exterior grades of "Hello", "Aqua", "Flourishing", "Eurotex", "Bor".
