The importance of paint gloss detection | Gloss detection instrument

In our daily life, paint products and paint brushes can be seen everywhere. It can be said that paint has a strong sense of life participation. For the amateur, a gloss Tester can more reliably detect paint gloss. 

Paint is a compound. Its raw materials are inseparable from base pigments, solvents, additives and other substances. The paint brush is suitable for the surface of furniture, pipes, buildings, plastic products and other objects, which can strongly prevent the entry of external dust and moisture. Chemical reactions and product corrosion can also be avoided. Additionally, the proper use of paint during renovations can improve the look, match the color of the home, and reduce accidental scratch damage from everyday life. The gloss Tester is a professional measuring equipment developed by the property.

There are many factors that affect the gloss of paint. The future use and maintenance are irresistible external factors, which we will not discuss for now. The main reason is to use a gloss Tester to explore the internal structure and external measurement of paint gloss. Generally speaking, we can discuss from the aspects of pigment particle size, solvent used in the paint, and the measurement angle of the gloss Tester.

The pigment particle size of a paint is inversely proportional to its gloss. Generally, the smaller the particle size of the pigment, that is, the finer the powder, the higher the gloss of the paint. The larger the pigment particles, the lower the gloss and the worse the stability. In addition, when we use a professional gloss Tester to test, we will also find that the paint with high gloss value has a more uniform particle distribution inside. Therefore, avoiding excessive dispersion of internal particles is also an important link that cannot be ignored in the production of coatings.

When making paint, we inevitably need to use solvents. The type of solvent used is also a matter of great knowledge, as some solvents are more or less volatile. The evaporation rate is too fast or too slow, resulting in insufficient smoothness of the coating film. An uneven paint film will directly affect its actual gloss value, which can be visually detected and displayed with a gloss Tester.

The selection of the measurement angle of the gloss meter is an important factor affecting the test results of the paint gloss. Gloss Testers on the market will be classified according to different measurement angles (20°, 45°, 60°). In general, the greater the incident angle measured with a measuring instrument (gloss Tester), the stronger the reflected light.
