Kinds of glues and their feature

The basic information on structure and glue characteristics, and also technologies of pasting will help you to understand, what glue is necessary for each concrete case.

• Dispersive glues. Represent water solutions of the smallest particles of artificial pitches. Such glues harden only after an exit of water from a solution. They are used mainly for pasting on the big surfaces of such materials, as a tree, a paper, a cardboard, the fabrics, capable to pass water.

• Contact glues. Consist of the viscous grades of rubber dissolved in organic solvent. Both stuck together surfaces grease and after solvent evaporation make short-term compression. The clamp or heavy cargo Here is required.

• Two-componental glues. They do not contain some solvent and consist of artificial pitch and a hardener. After mixing there is a process of polymerisation and in several minutes there is a sufficient initial durability. These glues approach almost for all materials and their combinations, providing extremely high durability and filling of cracks. At contact to a skin or eyes their contents can cause irritation.

• High-speed glues. He contain solvents and seize on air within several seconds. They are applied at pasting only very small surfaces. Because of fast and strong shvatyvanija are dangerous at contacts to a skin. Them put a thin and uniform layer. At small stuck together surfaces it is possible to put glue directly from a tube, and at the big it is necessary to use a brush or gear shpatel.

• Fusible glues. These are new enough, strong and convenient glues in the use. They are issued for various materials in the form of fusible cores and are used only in the warmed up condition. The tool for a warming up and drawing of such glues is the special electric pistol.
