Paints And Coatings The Difference Of Existence

During the renovation process, sometimes the owners need to buy their own paint, when the paint master told to buy a certain brand of paint to see the above is written in the paint. Is paint and paint the same thing? If not, what is the difference between paint and paint?

The Evolution of the Concept of Paint Coatings

Paint in our country has a long history. The reason why called paint, from the early this material can not be separated from vegetable oil and paint, so "paint" the word carrying a heavy history and ancient culture. With the continuous development of science and technology, the paint industry has grown, the variety of paint, category has also been innovative.

The term "paint" has appeared in the 1950s. In the industry has always been that the paint and paint is only the same material of the two different names only. 20th century, 50-60 years, and even to the 1970s, the industry will be more "paint" understood as learning, the "paint" understood as commonly known. Therefore, when the "paint" the number of titles with some academic taste, it seems that only research units can enjoy the title of paint, such as paint research institute or paint research. At the same time, where the production enterprises are known as the paint factory, paint factory or paint factory.

The confusion of paint and paint names began after the 1980s. With the rapid development of economic construction, the rapid rise of the construction industry, the paint industry is no longer a monopoly of the past chemical system situation. A large number of new domestic construction system similar to the production plant commonly used "paint" as a business name. With the large number of architectural coatings products into the market, "paint" not only from the sacred academic hall came out, but also because the architectural coatings are mainly water-based products, the concept of paint and therefore social misinterpretation, one-sided view that the paint is water , Mistakenly believe that paint and paint are two different materials, belong to two different industries.

GB notes on paint and paint

National Standard (GB 5206.1) In the basic terminology of paint and varnish vocabulary standards, coatings are defined by the fact that they are applied to the surface of the object to form a solid coating with protective, decorative or special properties such as insulation, corrosion, marking, etc. A general term for a class of liquid or solid materials. Most of the early vegetable oil as the main raw material, it is known as paint. Now synthetic resin has been replaced by most or all of the vegetable oil, so called paint.

For the above definition, the following two views:

1, now the reason why such materials are not called paint paint, more is due to the development of paint varieties and categories, because the name of the paint can not cover the industry's existing products, and the term paint can be covered Industry all kinds of products, the use of paint name more accurate and more scientific. Such as powder coating products should not use the title of paint, paint and paint here is not interchangeable. Therefore, the paint can cover the solid powder coating and liquid paint, and the replacement is not, so the standard interpretation is not in place.

2, the standard in the paint terminology of the "Note": that "in the specific name of the paint can be used to express the 'paint' words, such as blending paint, thick paint, etc." is also wrong. Because in fact the "paint" is not only used in specific paint varieties, but also a large number of used in the paint category, such as acrylic paint, polyurethane paint, etc., but also a large number of applications in the field refers to, such as corrosion Paint, car paint, ship paint and so on. In fact, in addition to individual circumstances, the paint and paint the word is common, it does not specifically refers to the specific species can be expressed.

Paint the concept of paint should be amended

The apparent characteristics of the paint, the paint is liquid, it can not cover the solid paint other than liquid paint. Since the scope of coverage is different, it would be difficult to explain if the paint is interpreted in the same way as the paint concept.

At present, water-based paint and powder coating has become a climate, especially in water-based paint-based architectural coatings in China's total paint accounted for about 38%. As the water-based paint and oily paint its chemical properties are essentially different, water-based paint and oily paint product properties are also very different, then the water-based paint as a major branch of the paint industry's old understanding is unscientific The Water-based paint and oil (paint) should be tied as two different series of liquid coatings.

Therefore, in the basic terminology standards, not only need to properly amend the standard coating terms, but also paint, paint and water-based paint terminology standards. They are defined as:

A general term for a class of liquid or solid materials that can be applied to the surface of an object to form a solid coating with protective, decorative or special properties such as insulation, corrosion, marking, and the like. Including oil (paint), water-based paint, powder coating.

Paint: Flowable liquid coating. Including oil (paint) and water-based paint.

Paint: An organic solvent as a medium or a highly solid, solvent-free oily paint.

Water-based paint: water can be dissolved or water-dispersed paint.

The above is the difference between paint and paint.
