PVA glue, the technical characteristics of which you can see below, is an aqueous 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 according to the type of wood, paper, fabric and leather.
Household and building PVC
PVA glue, the technical characteristics of which will help you make the right choice, can be household, it is also sometimes called wallpaper. It is used for gluing paper-based products to wood, plaster and cement surfaces. There is another version of this composition, which is called building and is used for gluing fiberglass, paper and vinyl wallpapers. This mixture can be added to primers to improve the technological and adhesive qualities, as well as plaster and coating compositions.
Universal PVC
PVA glue, the technical characteristics of which are presented in the article, can be universal. It has the appearance of a uniform viscous mass of white or yellowish tint. Used to glue paper or fabric on glass, wood or metal surfaces. It is used as a component of putties, primers, cement compositions made on a water base. The universal composition of this kind allows you to stick linoleum, tile, carpet, wall synthetic coatings to the surface. Gluing can be done on a building grid, paper base or cork coverings.
Specifications
Office PVA glue, the technical characteristics of which will help the reader, has a creamy consistency and has the smell of vinyl alcohol. This composition is not toxic, it is harmless to the skin. Additives are environmentally friendly, and among the main characteristics one can distinguish excellent adhesive abilities, which vary from 400 to 550 N / m. The composition is not explosive or fire hazard, has the qualities of moisture resistance and moisture resistance. PVA glue is universal, the technical characteristics of which make consumers incline their choice in his direction, is non-toxic and can even be used on playgrounds. It dries with the smallest shrinkage and is able to fill all 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. Adhesive has a low cost, which indicates accessibility to the consumer.
Extra-E Features
With the help of this composition, products made from vapor-permeable materials are bonded. The latter do not have special requirements for bonding and operation technology. The composition is designed to work with plywood, wood, paper and cardboard.
Features of glue dispersion
PVA glue, the technical characteristics of which must be read before purchase, acts as an additive for building mixtures used in glass, printing, shoe and other fields. Adding dispersion improves the adhesion quality and gives the product strength and ductility.
GOST 18992-80
Glue PVA, technical specifications, GOST of which are presented above, has frost resistance, which manifests itself over 4 cycles. You can store the composition after manufacture for six months. This mixture shows a low consumption. Per square meter, it 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 solidification occurs in a day.
The seam is elastic and high strength. Freezing does not contribute to fragility and allows you to work with gaps, the width of which is several millimeters. The emulsified component is soluble in organic substances and acetic acid. The mixture is partially soluble in water.
Adhesive Tips
When using the composition in repair or construction, its application can be carried out using a special nozzle or syringe. Manipulations should be carried out 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, the compression may be long or short. The first case relates to technology, which involves the use of a vice.
Conclusion
When gluing paper, the formation of bubbles should be eliminated, this effect can be achieved using a roller. If the composition got on the front surface, then it can be eliminated using a product called anticlay.
