Universal glue "Moment Crystal": description and application

In everyday life, the universal glue "Moment Crystal" is irreplaceable. It helps to bond a wide variety of materials, from ceramics to rubber. But the main advantage of this tool is that the traces of gluing are almost invisible. The composition is deservedly popular - it has high quality and excellent performance properties.

The adhesive has a complex chemical composition, created using the latest technologies, which determines its basic properties. This is a product that allows you to form a high strength seam, resistant to aggressive influences (including mechanical).

The product includes the following main components:

• inorganic heterochain polymers of the polyurethane group obtained by high-temperature synthesis;
• ethyl acetate (ethyl ester of ethanoic acid);
• dimethyl ketone or acetone;
• stabilizing additives.

The products are packed in tubes of 125 ml and 30 ml. You can also buy glue in cans of 750 ml and cans of 10 liters. The latter option is especially convenient if large volumes of repair work are planned.

Polyurethane glue is capable of gluing hard and soft materials from polystyrene, polyvinyl chloride and other types of synthetic polymer products. It can also be used for bonding wood materials, natural plant cork, acrylic resin organic glass, metal, ceramic and porcelain, rubber, paper and cardboard.

Main technical and operational characteristics of the product:

• the product is a transparent gel that remains colorless even after hardening;
• suitable for gluing various combinations of materials;
• is a water-resistant composition, therefore it can be used for products made of natural and synthetic rubber (rubber);
• not subject to aggressive alkaline and acidic effects;
• has the ability to crystallize during solidification, provides perfect adhesion to surfaces;
• possesses high strength properties, after processing does not leave dirty marks and stains;
• processed seams are not affected by high and low temperatures (from -40 to +70 degrees);
• you do not need to use solvents to remove excess adhesive - they can be removed mechanically or by rolling them with your fingers.

A feature of the glue is the restoration of its required properties after freezing. It is able to regain its original consistency at room temperature.

The Moment Crystal universal gel can dry out, crystallize prematurely and become unusable only if the package is not sealed. Storage of the product provides for an average temperature of -20 to +30 degrees for 24 months.

There are two main limitations in the use of glue:

• it cannot be used for gluing utensils used for food;
• it is not suitable for repairing PP, PE and Teflon products.

The adhesive, having maximum adhesion, sets instantly, because the composition is recognized as the highest quality and most durable among analogues.However, before use, as stated in the product description, the surfaces to be joined must be prepared. If it is metal, it should be cleaned of scale, rust, dust and dirt. After that, it is advisable to grind the coating with any abrasive and wipe it off, removing small particles. Then you can degrease the material with acetone or gasoline.

The composition is applied in an even layer only on dry clean surfaces and left until a thin but noticeable film forms on them (for 20-25 minutes). With high porosity of the processed products, the glue can be absorbed well, so it will have to be applied again.

Before bonding the coatings, make sure that the transparent film is in the correct consistency. If it does not stick to your hands, then you can connect the sections. This must be done quickly, with strong pressure - the strength of the seam depends on it. The closure should be uniform over the entire surface area so that air bubbles do not form.

For maximum strength, it is not the duration of the pressure that is important, but its strength, therefore, the gluing must be done as carefully as possible. It is worth pressing the surface for 5-7 seconds. After that, it will no longer be possible to make adjustments. To create optimal uniform pressure during gluing, professional craftsmen recommend using an ordinary rolling pin or bottle. You can use the product after repair a day later, when the polymerization of the adhesive is completely completed.

Usually glue does not stain, but sometimes it is necessary to remove its remnantsaccidentally hitting the surface. This must be done quickly. Fresh dirt can be removed with a clean finger. Dried stains can be removed with gasoline or acetone (with the exception of fabrics that have to be taken to dry cleaning).

When using the product, do not forget that the product is flammable, therefore, all gluing work should not be carried out near sources of fire. It is also desirable to provide maximum ventilation in the room.

Adhesive fumes in some cases can cause an allergic reaction, dizziness, bouts of nausea and vomiting in people with hypersensitivity. It is unacceptable that the product gets on the skin and mucous membranes of the eyes.

In addition to the universal glue, the line of Moment products is represented by other popular formulations.

• "Moment gel" intended for vertical gluing at home.
• "Super Moment" provides instant bonding.
• "Super Moment gel" designed for vertical coatings characterized by increased porosity.
• Series "Moment Montage" - a range of tools for installation work, suitable for all working surfaces.

Today, judging by the reviews, the Moment universal waterproof glue from the manufacturer Henkel is in the greatest demand. If stored properly, it can be used for several years. However, he does not lose his valuable qualities. The product has a low cost, sticks together almost everything (including natural and artificial leather). The glue has only one drawback - a pungent odor, which is explained by the presence of acetone and other active components in the composition, therefore it is advisable to work with the agent with open windows.
