Varieties and properties of dichloroethane glue, instructions for use

The dichloroethane content of the glue gives it the properties necessary for the assembly of Plexiglas and bodywork plastic. The solution is available in several forms, which differ in a number of characteristics, so before buying it is worth getting acquainted with the features of the product.

What is dichloroethane

Dichloroethane is a colorless volatile liquid that belongs to organochlorine compounds and has a specific pronounced odor. The substance is easily soluble in fats and alcohol, and is often included in household products. To obtain an adhesive solution, dichloroethane is diluted with 10% polystyrene or 2% plexiglass. The liquid can only be used for industrial purposes.

Varieties and properties of adhesives

In the construction market, you can find several types of dichloroethane glues. Each variety has individual adhesive properties. Before starting work, you need to study the features of each option and choose the right one, taking into account the tasks and your own requirements.

Liquid

The liquid adhesive is water-based and solvent-based. Once hardened, the solvent evaporates and the substance becomes solid and ensures a secure connection of the parts.This variety is suitable for interior decoration with porous materials, including fabrics, wood and plastic. At the same time, the liquid solution does not stick the sealed materials, since in contact with them it does not even begin to harden.

Contact

Contact formulations can be with or without hardener. The principle of using the solution is simple - a contact adhesive of viscous consistency is applied to both surfaces to be joined, where it should dry slightly, after which the surfaces are applied to each other and held under pressure .

Rexant products are a common contact composition. An epoxy mixture with a hardener has a universal purpose and, among other things, is suitable for working with plastic surfaces. Like the rest of the contact category, Rexant takes a day to fully cure.

hot glue

Hot melt glue, also called reactive glue, must be warmed up before use. As a result of heating, the solution turns into a liquid state and solidifies upon further cooling. The need to use hot melt glue arises when fixing large elements. A popular version of the rocket train is the Moment.

Reactionary

The reaction variants of the solution with dichloroethane can be one- or two-component. This option is suitable for instant adjustment of materials, so it is important to carefully monitor the correct connection during use. The one-component composition is produced ready for use, and the two-component mixture will need to be diluted with water beforehand.

This composition retains its working properties for 20-30 minutes and should be cooked in small portions.

How to make dichloroethane glue yourself

Adhesive solution with dichloroethane can be prepared independently at home. It's not hard to do a mix of work; you will need to dissolve a small amount of material in a volatile substance, for which a solution is needed to stick. The step-by-step instructions for preparing the mixture include the following steps:

1. For the solution, take a glass container with a tightly closed lid. A tight seal is necessary due to the rapid evaporation property of dichloroethane.
2. Chips or small plastic particles are added to the container. The load must be completely submerged in the liquid.
3. The lid of the container is tightly twisted and the mixture is removed in a place limited to exposure to ultraviolet rays. You should also ensure that children do not have access to the solution.
4. After waiting for the complete dissolution of the plastic filler, you can use the prepared solution for its intended purpose.

When deciding on the proportions of dichloroethane and filler, you need to take into account the desired consistency of the finished solution. The more plastic you add, the thicker the working mixture becomes. If the glue becomes too thick, you can always dilute it with a liquid substance. Some experts use dichloroethane in its pure form in their work, or add a small amount of Plexiglas crumbs to it, observing a ratio of 1:10.

After preparing the working mixture, you need to check the adhesiveness on the waste material of the material in order to visually see what the reaction will be when the solution is applied. Then you can proceed to the main work if during the tests the mixture did not damage the material and formed a strong tear-resistant seam.

Manual

Dichloroethane adhesive is used taking into account the standard rules, but due to the characteristics of the volatile liquid there are a number of peculiarities. Considering all the nuances, there are the following instructions for use:

1. The plastic is dissolved in a small volume of the substance and the mixture is left to dissolve the filler.
2. The surface of the treated material is degreased with acetone.
3. The glue solution is applied exclusively to the seam site. It is important not to allow the working mixture to penetrate the rest of the surface, as the dichloroethane can corrode the material.
4. The edges of the seam are joined and pressed firmly against each other. For reliable fixation, the edges are fixed for 5-6 hours so that the solution has time to dry.

Precautionary measures

Standard safety precautions should be followed to ensure safe handling of dichloroethane adhesives. You can store the working mixture only in glass or plastic bottles, since the substance dissolves all other types of plastic. The liquid is also capable of corroding many other materials, so spills should be avoided.

Since dichloroethane evaporates quickly and gives off a strong odor, it can only be used in a constantly ventilated room, away from sources of fire or heating.

When handling the adhesive, it is recommended to wear protective gloves, a respirator and long-sleeved clothing to protect the skin. Considering all the listed restrictions and the toxicity of the substance, its use is allowed only for production purposes.

Additional tips and tricks

Ensuring a high-quality result and reliable connection of surfaces allows compliance with a number of additional recommendations of specialists.

Common tips include:

1. Avoid getting moisture on the glue line, as the liquid significantly alters the strength of the joint. Contact with water may dislodge bonded surfaces and break seal.
2. When gluing with a solution containing dichloroethane, it is possible to adjust the position of the surfaces for a long time. At the same time, you should not delay this process, as there is a risk of a large amount of glue coming out of the seam, which will negatively affect the quality of the connection.
3. The composition should be applied with maximum care. Otherwise, the substance can corrode the material and spoil the appearance of the part.
4. When pressing the surfaces after applying the adhesive, you must ensure that the joint is completely closed. The joining of the materials is fixed in a static position for several hours to dry the substance.
5. Due to the increased volatility of dichloroethane, chemical dishes are the optimal place for storing the substance. The container should always be tightly closed to prevent evaporation. Also, leaving the dichloroethane container open can easily spill liquid.
6. At work, it is better to use small bottles with a substance of 20-50 ml. Such containers are more stable and, if handled carelessly, a minimum amount of substance will spill out.
