At present, PVA glue is the most versatile type of glue, widely in demand in many areas. It is used both by schoolchildren in labor lessons and by professional masons 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 affordable price.
Traditional PVA glue is a homogeneous, rather viscous substance of white color, characterized by a high degree of strength (when gluing) and good frost resistance.
Modern industry produces several varieties of this product, which differ in composition and belonging to the load class, according to the water resistance standard. The choice of one or another adhesive directly depends on the area of \u200b\u200buse and the specific characteristics of the materials that will be glued. The end result largely depends on this.
PVA universal glue has such technicalcharacteristics, such as gluing ability 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 its application in a wide variety of fields. It is used both when laying ceramic tiles, and when covering walls with wallpaper, and even as a mandatory additive in glass production.
Stationery glue, the least toxic of all other types, is used to glue paper, cardboard or photographs. Joinery, with high water resistance and good adhesion, is used when working with a variety of furniture. Glue "Moment", characterized by a minimum pressing time, is used when laying laminate and parquet. In addition, there is a special PVA glue for wood and leather products. Such a product is also an essential component for primers and putties.
There is also an adhesive specially designed for ceramic tiling and flooring, PVA homopolymer adhesive used in the building materials manufacturing process, as well as in the textile and porcelain industries. The latter is the most powerfulsetting.
Ecological cleanliness, safety and reasonable price make any of the listed types of material a very useful acquisition. This, by the way, explains one of the reasons for its so high popularity. On its basis, they even produce "smart plasticine" - a special children's toy that can change its state and take on absolutely any shape.
The obvious advantage over other compounds of this kind is the main factor that today manufacturing companies are striving to improve the formulation of PVA glue, and not to invent new adhesives.
