Photos and descriptions of varnishes can be seen below.
General qualities of metal varnishes:
- Protection of how to choose the right disposable cups for different events from corrosion;
- Extend the shelf life of metal objects;
- High strength and wear resistance of the coating;
- Protecting the surface from moisture.
Bitumen varnish
Bitumen varnishes include: bitumen, resin, organic italy numbers as a solvent. When applying the varnish, it oxidizes, forming a dark layer. Its advantages:
- Frost resistance.
- Elasticity.
- Elasticity.
- Independence from the environment, high temperatures.
- Eco-friendly, have antiseptic properties.
- Varnishes are universal. You can varnish metals, stones, wood.
Bitumen varnish is durable and is us as a coating for a certain period of time.
Polyurethane
Thanks to polyurethane, the varnish acquires strength and resistance to corrosion. It is us for cast iron, copper, aluminum, forming an invisible layer, withstands temperatures from -60 to +80 degrees. The varnish is wear-resistant, chemically inert, moisture-resistant. The material is reliable, its effect will not stop for more than 10 years. The varnish is very easy to apply. It dries quickly, does not leak, and is transparent.
Acrylic
Acrylic varnish is water-resistant. It protects metal surfaces and their alloys us in high humidity. Acrylic varnish does not contain a solvent, it is consider safe and is suitable for indoor work. When applying varnish, there is no unpleasant smell.
Dries in 3 hours, forming a colorless layer that protects against moisture. Usually in the form of an aerosol, in cans. Can be in a can. Acrylic varnish has the following qualities:
- Resistant to high temperatures, adverse environments, high humidity, ultraviolet rays;
- Corrosion resistance;
- Safety;
- Non-flammability;
- Easy to apply, quick drying.
Alkyd
They contain resins and polymers. Dries to form a durable, moisture-resistant, colorless, glossy layer. It is us for finishing, when covering paint with a protective layer. Most often, it is an aerosol.
Stove
The most heat-resistant varnish for metals. Us to coat furnaces and metal parts. Furnace varnish is heat to 250 degrees, protects metals from rusting.
Stove varnishes can be dilut in others to improve their properties. Some varnishes simply protect metals from rust, while others are capable of restoring these surfaces.
Colors
Varnishes for metal coating are mostly transparent. But when choosing a varnish, not only the color is important, but also the smoothness after drying. There are:
- Matte varnish. It highlights the main color of the surface, does not shine, hides defects;
