Composition and types of stationery glue

Office supply stores amaze with a wealth of choice. And if for experienced artists and creative people in general this is a virtue, then novice craftsmen can really get confused. And even such a simple thing as clerical glue is found in many different forms in many manufacturers. Most often, parents whose children go to primary school face difficulties in choosing glue. You need to choose a tool suitable for creating simple crafts. At the same time, it should be convenient to use, safe, dry quickly and securely fasten the elements.

Types of glue

Office glue comes in three main forms:

• PVA;
• pencil;
• silicate.

Silicate glue was popular in Soviet times - for lack of special choice. Now it is still found in stores, but is not in demand. Now, when it became possible to compare it with other species, it became clear that the silicate substance has many disadvantages.

• After drying, the applied layer of glue changes color (which makes it completely unsuitable for creative work).
• Frozen adhesive layer, it is very fragile.
• When using such a tool, you can not hesitate - in air, the composition dries very quickly.
• In addition, when working with this species, care must be taken - there is a high risk of burns if the substance gets into the eyes.

PVA glue is more familiar to consumers. It is lightweight. It is also less toxic than its predecessor. Of course, when using it is also necessary to be careful, but you can not be afraid of such terrible consequences.

Glue stick is the most convenient to use - the child will definitely not get dirty during the creation of the craft. In addition, it dries very quickly. But large elements are not fastened by this species as reliably as liquid substances.

Composition

Such differences in the properties and release form of certain types of glue are explained by the difference in composition.

Silicate glue, as its name implies, consists of aqueous solutions of various silicates. Silicate is a silicic acid. Typically, an adhesive is made from a compound of such an acid and sodium or potassium. Less commonly used lithium.

PVA stationery glue has a completely different composition. It is made from polyvinyl acetate dissolved in water. It is a transparent substance that is odorless. To improve the quality of the glue, plasticizers are added to it.

Glue stick can be of two types, which differ in composition:

• based on PVA, in which water acts as a humidifier;
• from polyvinylpyrrolidone. In this case, glycerin is used as a humectant.

Tip

Do not buy PVP glue for creativity. It belongs to professional means because of its frost resistance. For crafts, ordinary PVA is also suitable.

Specifications

To begin, consider the general characteristics that are applicable to all types of stationery glue:

Let us dwell on the areas of application. Most often, clerical glue is used when working with paper. Therefore, it is most popular among office workers, schoolchildren and students.

But this tool is suitable and not only for simple gluing of sheets. You can’t do without it when creating paper applications. In addition, this type of glue will help fasten cardboard, wooden elements, small volumetric details like beads and buttons.

Characteristics of liquid glue:

• dries a little longer than its counterparts in the stick;
• fastens elements more reliably;
• more suitable for working with dense materials, since when applied, for example, to thin paper, it can deform.

Characteristics of glue stick:

• dries quickly;
• due to the application of a thin layer and consistency, the parts are not so securely fixed.

Manufacturers
