PVA glue: technical specifications and features

Glue PVA, the technical characteristics of which you can see below, is an aqueous dispersion of polyvinyl acetate, in the process of production, special substances and plasticizers are added to it. This composition is used for gluing all kinds of surfaces like wood, paper, fabric and leather.

Household and construction PVC

Glue PVA, the technical characteristics of which will help you decide the choice, maybe household, it is sometimes called wallpaper. It is used for gluing of products made on a paper basis, to wooden, plastered and cement surfaces. There is another kind of this composition, called construction and used for gluing fiberglass, paper and vinyl wallpaper. This mixture can be added to the primer to improve the technological and adhesion qualities, as well as plastering and facing compounds.

Universal PVC

Glue PVA, the technical characteristics of which are presented in the article, can be universal. It has the appearance of a homogeneous viscous mass of a white or yellowish hue. It is used for gluing paper or fabric on glass, wooden or metal surfaces. It is used as a component of putties, primers, cement compounds made on a water base. Universal composition of this kind allows you to glue to the surface of linoleum, tile, carpet, wall synthetic coatings. The gluing can be done on a building mesh, paper base or cork coverings.

Specifications

Glue PVA clerical, technical characteristics of which will help the reader, has a creamy consistency and has a 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 adhesives, which vary from 400 to 550 N / m. The composition is not explosive or fire-hazardous, has the qualities of moisture-proof and moisture-proof. Glue PVA universal, technical characteristics of which force consumers to choose in his direction, is non-toxic and can be used even on playgrounds. It dries with the most minimal shrinkage and is able to fill all the gaps. With its help, it is possible to form a transparent thin film, which has high strength. The composition is soluble in a number of appropriate substances, which expands the scope of use. The glue has a low cost, which indicates availability for the consumer.

Features of extra-E class

With the help of this composition, gluing of products made of vapor-permeable materials is carried out. The latter do not have special requirements for the technology of bonding and operation. The composition is intended for work with plywood, wood, paper and cardboard.

Features of adhesive dispersion

Glue PVA, the technical characteristics of which must be read before buying, acts as an additive for construction mixtures used in glass, printing, footwear and other fields. The addition of dispersion improves the adhesion and gives the product strength and ductility.

GOST 18992-80

PVA glue, technical characteristics, GOST of which are presented above, has frost resistance, which manifests itself during 4 cycles. Keep the composition after manufacturing can be six months. This mixture shows a low consumption. On a square meter will be required from 100 to 900 grams of composition, the final figure will depend on the type of work performed. Full freezing occurs every other day.

The seam is obtained by elastic and high strength. Freezing does not contribute to brittleness and allows you to work with gaps whose width is several millimeters. The emulsified component is soluble in organic substances and acetic acid. The mixture partially dissolves in water.

Tips for working with glue

When using the compound in repair or construction, it can be applied by means of 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 joint, the surfaces must be pressed against each other. Depending on the type of adhesive, the compression may be prolonged or short-term. The first case relates to a technology that involves the use of a vice.

Conclusion

When gluing paper, the formation of bubbles should be avoided, this effect can be achieved using a roller. If the composition has got on the front surface, then it can be removed with the help of a means called anti-glue.
