Composition of Moment Crystal glue

“Moment” consists of complex chemicals, many of which are inventions of recent generations. The basis is heterochain polymers from the polyurethane group. The composition also includes the following substances:

• ethyl acetic acid ester,
• acetone and other saturated ketones,
• stabilizers for other chemicals,
• aliphatic, naphthenic hydrocarbons,
• antioxidant,
• synthetic resins,
• ethyl acetate.

The presence of acetone and other solvents explains the pungent odor of “Moment”. Despite the harm of these components and the need to work in protective masks, the manufacturer positions the product as complying with international environmental norms and standards. The most harmful solvent, toluene, was removed from the formulation back in 1998, but from time to time counterfeits containing this substance are discovered on the market.

Performance properties and performance characteristics

The product is used for gluing a huge number of materials and has a minimum of restrictions. Applying a thin layer to only one side of the part and joining the elements ensures the highest strength of the adhesive seam. This is achieved due to the excellent level of adhesion. “Moment Crystal” is transparent, which only expands the scope of its use, because after gluing the joint will be completely invisible.

Main technical characteristics of the product:

• the recommended temperature when working with glue is from +15 to +30 degrees (it is possible at a different temperature, although the polymerization time will change),
• the operating temperature of the products after the adhesive joint has dried is from -35 to +75 degrees,
• high cold resistance - the seam can withstand several cycles of defrosting and freezing, the glue itself in the tube also quickly restores its original properties after defrosting,
• consumption – 200-400 g/sq.m. m (depending on the type of surface, purpose),
• moisture resistance, no changes in technical parameters even with direct exposure to water,
• resistance to ultraviolet radiation, the influence of dilute acids, weak alkalis,
• the optimal glue density is 0.88 g/cubic. cm.

When using "Moment" you need to be careful; it is highly flammable due to the presence of solvents in the composition. If you do not follow the manufacturer's recommendations for operating temperatures, the quality and performance characteristics of the adhesive joint will change, and it may become deformed.

The glue has several restrictions on its use. It is prohibited to use it to repair things made of Teflon, polypropylene, polyethylene. Also, glue should not be used for gluing dishes, other kitchen items and utensils that may come into contact with food. For plastic, there is not a ban, but a limitation: it is important to drop a little “Moment” onto an inconspicuous area and evaluate the reaction of the material within 30 minutes. If there is no yellowing or warping of the material, you can safely use glue for work.

It perfectly glues wood, metal, rubber, porcelain and other types of surfaces, providing the joint with incredible strength. This glue is also applicable to various types of fabric, since it leaves absolutely no marks, stains or other defects on the surfaces treated with it.

Modern manufacturers produce Moment Crystal glue in a metal tube, the volume of which is 30 ml and 125 ml.

Crystal glue is transparent and demonstrates high resistance to high humidity and does not change its parameters with small changes in ambient temperature, which makes the “Moment Crystal” composition extremely popular in the domestic market. This is confirmed by numerous positive reviews from experienced builders and those buyers who prefer to carry out construction and repair work on their own.

Instructions for use

All tips for working with glue are indicated on the packaging. To obtain a high-quality adhesive joint, the base must first be prepared - cleaned of dirt, treated with fine-grain sandpaper. To remove grease stains and oil films, both surfaces to be bonded should be degreased. For this purpose, it is best to wipe them with alcohol or acetone, which will also help remove paint residues. You can also wash the products with household detergents.

Here are some tips for working with glue:

• apply glue to one of the surfaces if they are homogeneous, and to both when dissimilar materials are glued together,
• if the bases are porous, repeat the application of glue after a couple of minutes,
• press the products against each other from the center to the edges to prevent air from accumulating, fix in any convenient way,
• if possible, it is allowed to use a special roller for rolling parts,
• stand for 10-20 minutes,
• Before full use, leave the product for a day (to increase the strength of the adhesive seam).

You can make adjustments to the position of the parts only immediately after they are applied to each other. It is allowed to separate objects with immediate re-gluing. After 5-7 minutes it will be impossible to do this; you will have to remove the glue from the base and repeat all the manipulations. The manufacturer does not recommend gluing in rooms with high humidity. Despite the moisture resistance of the adhesive joint, at the time of connection it is necessary to exclude the action of liquid in one form or another.

Sometimes it happens that glue gets on clothes, other objects, or hands. You can remove already dried glue using acetone or gasoline. It is better to dry clean the fabric or try washing it with powder, detergents, or wipe with alcohol. The glue is removed from the tools with gasoline, in which they are soaked for 1-2 hours.

How to use correctly

For the strongest and most durable connection, all manufacturer’s recommendations should be followed.

• Remove dirt from the surfaces to be bonded. Lightly roughen the surface using fine-grit sandpaper. You can get rid of grease stains with a degreaser or solvent. For the last task, acetone and pure alcohol can be used. Such substances will also help clean surfaces from old layers of paint and varnish. Additionally, household chemicals help get rid of excess traces.
• Apply glue to the required surfaces. If the base is of the same material, then only one part needs to be coated with glue. Otherwise, Moment should be applied to both bases.
• If the surfaces have a smooth structure and contain pores, then after a few minutes it is recommended to reapply the glue.
• The parts must be pressed together. If the bases are flat, you can clamp them in a vice or roll them with a small roller if possible, so that every millimeter is involved in gluing.
• Initial adhesion is achieved after 20 minutes. It takes a day for the seam to harden as much as possible and the part to be fully usable.

Correction of the position of the surfaces is possible immediately after gluing. After a few minutes the position cannot be changed. You will have to separate the bases, clean off the old layer of glue again and repeat all the steps again.

Precautionary measures

The glue is flammable, so the following safety precautions should be observed when working with it:

• do not open the packaging near any sources of fire,
• do not apply glue to products located near sources of elevated temperature,
• Do not apply glue to heated surfaces.

All actions with “Moment” are carried out only in a ventilated room (hoods or through ventilation are used). When working for a long time, even with forced ventilation, you need to wear a respirator! You should work in special clothing and gloves. If glue gets on your hands or other exposed skin, you should immediately wash them with plenty of soap and water. If the product gets into the eyes or other mucous membranes, it is important to rinse them and immediately seek medical help.

How to use it in practice?

Moment Crystal glue is transparent and copes with the task perfectly: according to consumer reviews, connections made with this substance do not lose their strength for a long time.

According to the instructions: in order to glue the surfaces, they will first need to be thoroughly dried and cleaned with fine-grained sandpaper. Then they are degreased with acetone or gasoline, after which an even layer of glue is applied to the material. Moreover, we note that both surfaces must be coated with the adhesive, and not just one. This is a common mistake made by inexperienced buyers.

Then you will need to wait about 10 minutes and firmly press the surfaces to be joined for a few more seconds. In this case, the effectiveness of the operation will largely depend on the force applied, and not on the duration of the pressure.

As a result, you can obtain a truly effective combination of materials of different natures, resistant to wear, the negative effects of high temperatures, humidity or weak solutions of acid and alkali.

When performing work, it is tedious to remember that the composition may ignite. Therefore, all operations with it must be performed exclusively away from a source of open fire and in a well-ventilated room.

It is also worth considering that all work for human safety must be carried out in special clothing. If Moment Crystal glue gets on an open area of ​​skin, it can cause irritation, burning, allergies and other skin disorders.

You should be especially careful if children live in the house. Transparent glue Moment Crystal 125 ml should be securely hidden from the hands of a child.

Universal glue Moment Crystal has become simply indispensable in everyday life. It allows you to quickly glue different materials - from ceramics to rubber. Its main advantage is the almost complete invisibility of traces from the connection of parts. The adhesive composition is high quality and has excellent characteristics.

Moment is a universal adhesive, transparent, its composition is waterproof. With it you can reliably and permanently glue different materials.

The crystal qualitatively connects wood, metal, porcelain, rubber and other surfaces. The joint area is provided with high strength. The glue can also be used for fabrics, because it does not leave marks or stains and does not deform the processed material.

The crystal does not change its parameters even under the influence of high humidity or temperature changes. Thanks to this, it is in great demand and has a large number of positive reviews from experienced builders and from those who prefer to do all the work themselves.

The glue has a complex chemical composition; the latest technologies are used to create it. The main components are:

• polymers from the group of polyurethanes;
• ethyl acetate;
• acetone;
• stabilizers.

Stabilizers increase resistance to moisture. As it hardens, it crystallizes, due to which the joints have high strength.

Glue storage

The product should only be stored in its original packaging, tightly closed. The storage location should be located out of the reach of children, animals, sunlight and away from possible heating. It is desirable that the temperature is not lower than room temperature, but freezing the glue is also allowed (after defrosting it will retain its properties). Temperature standards for storage are from -20 to +30 degrees, period is up to 2 years.

It is forbidden to throw used Moment packaging into the fire! It is disposed of along with household waste. If all recommendations are followed, the glue does not pose a danger to human life or health.
