PVA glue, whose specifications youcan see below, is a water dispersion of polyvinyl acetate, during the production process special substances and plasticizers are added to it. This composition is used for bonding all kinds of surfaces by type of wood, paper, fabric and leather.
Household and construction PVC
PVA glue, the technical characteristics of which youwill help determine the choice, perhaps household, it is also sometimes called wallpaper. It is used for gluing products made on paper to wood, plastered and cement surfaces. There is another kind of this composition, which is called construction and is used for bonding fiberglass, paper and vinyl wallpaper. This mixture can be added to the primer compositions to improve the technological and adhesive qualities, as well as plastering and facing compositions.
Universal PVC
PVA glue, technical characteristics of whichpresented in the article can be universal. It has the appearance of a uniform viscous mass of white or yellowish tint. Used for sticking paper or cloth on glass, wood or metal surfaces. It is used as a component of putties, primers, cement formulations made on a water base. The universal composition of this kind allows you to stick to the surface of linoleum, tile, carpet, wall synthetic coatings. Gluing can be done on a building grid, paper base or cork cover.
Specifications
PVA glue office, technical characteristicswhich will help the reader, has a creamy consistency and has the smell of vinyl alcohol. This composition is not poisonous, it is harmless to the skin. Additives are environmentally friendly, and among the main characteristics can be distinguished excellent adhesion, which vary from 400 to 550 N / m. The composition is not explosive or flammable, has the qualities of moisture resistance and moisture resistance. The PVA glue is universal, the technical characteristics of which make consumers incline their choice precisely in its direction, is non-toxic and can be used even in children's playgrounds. It dries out with the most minimal shrinkage and is able to fill all the gaps. With it, you can form a transparent thin film that has high strength. The composition is soluble in a number of relevant substances, which expands the scope of use. Glue has a low cost, which indicates the availability to the consumer.
Features of class extra-e
With the help of this composition is carried outbonding products made from vapor-permeable materials. The latter do not have special requirements for bonding technology and operation. The composition is designed to work with plywood, wood, paper and cardboard.
Features of adhesive dispersion
PVA glue, technical characteristics of whichmust be read before buying, acts as an additive for building mixtures used in glass, printing, footwear and other areas. Adding dispersion improves the quality of adhesion and gives the product strength and ductility.
GOST 18992-80
PVA glue, technical characteristics, GOSTwhich are presented above, has a frost resistance, which manifests itself for 4 cycles. Store composition after production can be six months. This mixture shows low consumption. Per square meter will be necessary from 100 to 900 grams of the composition, the final figure will depend on the type of work being carried out. Full hardening occurs in a day.
The seam turns out elastic and high-strength.Freezing is not conducive to fragility and allows working with gaps whose width is equal to several millimeters. The emulsified component is soluble in organic matter and acetic acid. The mixture is partially soluble in water.
Glue tips
When using the composition in repair orthe construction of its application can be made using a special nozzle or syringe. Manipulations should be made from the central part of the product to the edges. In order to increase the strength of the connection, the surface must be pressed against each other. Depending on the type of glue, compression can be long or short-term. The first case relates to a technology that involves the use of a vice.
Conclusion
When gluing paper should be excludedthe formation of bubbles, this effect can be achieved using a roller. If the composition got on the front surface, then you can eliminate it with the help of a tool called anti-adhesive.
