В настоящее время клей ПВА является самым universal type of glue, widely demanded in many areas. It is used by both schoolchildren in labor classes and professional bricklayers for laying ceramic tiles. The high popularity of this material is due to the simplicity and ease of use, the absence of toxic emissions and an affordable price.
Modern industry produces severalvarieties of this product, which differ in composition and class of loads, according to the water resistance standard. The choice of an adhesive substance depends on the area of use and the specific characteristics of the materials that will be glued together. From this depends largely on the final result.
Universal PVA glue has suchtechnical characteristics, such as gluing capacity equal to 400-450 N / m, low consumption, ranging from one hundred to nine hundred grams per square meter (depending on the type of work), high frost resistance, which is more than four cycles.
In addition, it is worth noting the period of complete drying, as a rule, not exceeding twenty-four hours, and a rather long shelf life of six to seven months.
Today, PVA glue finds itsapplication in the most various fields of activity. It is used both when laying ceramic tiles, and when covering walls with wallpaper, and even as a mandatory additive in glass production.

On its basis, even produce "smart clay" - a special children's toy that can change its state and take absolutely any form.
