How to distinguish the "function" in the promotion of coating products?

Multifunctional coatings are sought after

In some building materials supermarkets, many coatings claim to have some special functions such as antibacterial, anti-mildew, anti-cracking, and anti-formaldehyde, and "anti-formaldehyde" has almost become one of the "must-have" functions of coatings-Dulux Effective wall paint, marked with innovative silver ion antibacterial technology, can resist formaldehyde, benzene, and antibacterial.

Consumer Mr.

In a certain brand of paint store, the salesperson said that the anti-cracking function can cover up small cracks on the wall, and the odor-cleaning function is that the paint itself is tasteless and can be used immediately.

In fact, some consumers also have questions about the additional functions of coatings.

Special functions are limited

Many consumers “will rather believe that they have the additional functions such as anti-formaldehyde” promoted by coatings.

Take anti-formaldehyde as an example.

For the various functions of coatings on the market, are there relevant standards to define? Zhao Ling, secretary general of the National Coatings and Pigment Standardization Technical Committee, said that the current industry standard for functional coatings in the coatings industry "antibacterial coatings" classifies products as anti-bacterial performance Divided into two levels: products with antibacterial properties greater than 99% are products with strong antibacterial properties and belong to level I; products with antibacterial properties greater than 90% and less than 99% are products with antibacterial properties and belong to level II.

　　Regarding the performance of some products that claim to be resistant to cracking and mildew, Zhao Ling said that whether the wall is cracked is mainly related to the basic treatment of the wall, and has little to do with the paint itself, and the paint can only play some auxiliary functions.

　　In view of the additional functions claimed by some coatings on the market, relevant experts have made detailed analysis——

　　Basic function is the key

　　Many consumers regard "resistance to formaldehyde", "clean odor", "antibacterial" and other functions as the primary factors in choosing coatings, but pay little attention to basic functions such as "waterproof", "anti-crack" and "anti-mold".

　　According to reports, a good-quality paint should have good lubricity and viscosity, and smell a light fragrance.

　　"The choice of paint should pay attention to the adhesion of the paint and the content of VOC, especially the VOC content is the most important criterion for judging the quality of the paint.

　　The right amount of VOC is harmless to the human body

　　At present, many coating products advertise that they do not contain formaldehyde, have no artificial VOC or ultra-low VOC, which is more healthy and environmentally friendly.

　　In fact, there are many types of organic volatiles in coatings, and most of the ingredients cannot be confirmed as harmful.

　　It should be noted that the less VOC content in the coating is of course the better, but the businessmen overemphasize the concepts of formaldehyde and VOC in the coating, and they are using consumers' lack of relevant knowledge to mislead consumption.

　　Compliance with standards, safety and guarantee

　　Many businesses regard free color grading as a value-added service to attract consumers.
However, many consumers worry that the more paint the more beautiful, will the content of heavy metals increase?

　　In fact, the national standard GB18582-2008 "Limits of Hazardous Substances in Interior Decoration Materials and Interior Wall Paints" stipulates a limited amount of heavy metals in paints, requiring lead Pt≤90mg/kg, cadmium Cd≤75mg/kg, chromium Cr≤ 60mg/kg, mercury Hg≤60mg/kg, as long as it is a product that meets the requirements of the standard, it will not cause harm to human health.

　　Anti-mildew and antibacterial effect is limited

　　At present, most paints claim to have anti-mildew function, and can inhibit mold and protect walls.
The antibacterial function is claimed to inhibit the growth of bacteria and protect health.

　　In fact, the significance of antibacterial is to inhibit the growth of the number of bacteria.
If the coating has a certain anti-mildew function, it has a certain meaning.
The cost of antibacterial technology itself is low, and the product is likely to add antibacterial function to increase its selling point while being anti-mildew.
However, people have little contact with the wall in daily life, and antibacterial is of little significance.
