Also on sale is specialized means"Moment" - for rubber, plastic, boats and PVC, cork. For any material, the universal glue "Moment Gold Standard" is suitable.

The composition of the glue "Moment Crystal"

"Moment" is made up of complex chemicals, many of which are inventions of the latest generations. The basis is heterochain polymers from the polyurethane group. The composition is also represented by the following substances:

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

The presence of acetone and other solvents explains the pungent smell 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 fakes containing this substance are periodically found on the market.

Working properties and performance characteristics

The tool is used for gluing a huge number of materials, has a minimum of restrictions. Applying only one side of the part with a thin layer and joining the elements provide 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 operation, because after gluing the joint will be completely invisible.

Main technical characteristics of the product:

the recommended temperature while working with glue is from +15 to +30 degrees (it is possible at a different temperature, although the polymerization time will change);
operating temperature of products after the adhesive joint has dried - from -35 to +75 degrees;
high cold resistance - the seam withstands 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 (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 density of the glue is 0.88 g / cu. cm.

When using the "Moment" care must be taken, it is highly flammable due to the presence of solvents in the composition. If you do not follow the recommendations indicated by the manufacturer for operating temperatures, the quality and performance of the adhesive joint will change, it may be deformed.

Glue has several restrictions on use. It is forbidden 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 restriction: it is important to drop a little "Moment" on an inconspicuous area, evaluate the reaction of the material within 30 minutes. If there is no yellowing, warping of the material, you can safely use glue for work.

Application area

The instruction says that the best adhesion rates are achieved when using glue on materials such as PVC (hard, soft), porcelain and ceramics, polystyrene and plexiglass, ordinary glass. Glue is also used for gluing leather products (natural, artificial), fabric and cork, cardboard and paper, foam rubber and rubber. No less high quality will be the place of gluing when applied to wood, metal. It is thanks to this variety of purposes that glue is considered universal.

You can use "Moment Crystal" for various household, repair, restoration work. Since it is moisture resistant, it is suitable for products in contact with water and other non-aggressive liquids. You can use the tool at home, in production, in the service sector.

Advantages and disadvantages

Glue is now in great demand on the market, because it has a lot of advantages and compares favorably with analogues. Its advantages:

low price, availability in almost all household, construction, department stores;

Also on sale is "Moment Crystal" in tubes of 125 ml in a show box, cans of glue with a volume of 750 ml are sold. In specialized, branded, construction stores, at the bases there are canisters of 10 liters of glue.

Instructions for use

All tips for working with glue are indicated on the package. To obtain a high-quality adhesive seam, the base must first be prepared - cleaned of dirt, treated with fine-grained sandpaper. To remove grease stains, oil film, both surfaces to be glued must be degreased. For this purpose, it is best to wipe them with alcohol, acetone, which will also help remove remnants of paint and varnish coatings. You can also wash products with household detergents.

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 in order to prevent air from accumulating, fix in any convenient way;
if possible, it is allowed to use a special roller for rolling parts;
withstand 10-20 minutes;
before full operation, leave the product for a day (to gain strength of the adhesive seam).

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

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

Precautionary measures

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

do not open the package near any sources of fire;
do not apply glue to products located near sources of high temperature;
do not glue heated surfaces.

All actions with the "Moment" are carried out only in a ventilated room (exhaust hoods or through ventilation are used). When working for a long time, even with forced ventilation, you must wear a respirator! Work should be in overalls, gloves. If glue gets on hands, other open skin areas, they should be washed immediately with plenty of soap and water. If the agent enters the eyes, other mucous membranes, it is important to rinse them and immediately seek medical help.

Glue storage

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

Specifications

Moment Crystal adhesive contains stabilizing agents, heterochain polymers of the polyurethane group, acetic acid ethyl ester and acetone. Due to the presence of these components, the adhesive has high water resistance and is suitable for use in environments with high humidity. The tool is absolutely transparent, as a result of which the junction of the elements is almost imperceptible. During the drying process, the composition crystallizes, which ensures a high degree of adhesion of the parts and guarantees the durability of the connection. The glue is characterized by high heat and frost resistance and well tolerates the action of alkalis and dilute acids.

Glued things can be used at temperatures from -40 to 70 degrees without the risk of seam deformation or mutual displacement of parts. The optimum temperature for installation work the range plus 18-25 degrees is considered, but if necessary, gluing can be carried out both at lower and at higher temperatures.

If the work with the composition is carried out in extreme conditions, it must be borne in mind that the drying of the adhesive depends entirely on the evaporation time of the solvent. The slower this process takes place, the more time it will take for the complete polymerization of the seam.

"Moment Crystal", like many other compounds in this category, is a flammable substance. Therefore, bonding work must be carried out away from sources of open flame and with good ventilation, if installation is carried out indoors. The density of the adhesive is 0.88 g/cm3, and the average consumption, subject to the application of the composition on both surfaces, varies from 250 to 350 g/m2. The product can be stored at temperatures from -20 to 30 degrees and, in case of freezing, quickly restores its properties after thawing. The shelf life of the adhesive is limited to two years, subject to the storage temperature.

Application of glue Moment Crystal (15 photos)

Gluing polymer products can be a real challenge, as they are quite difficult to this type of processing. It is much easier to bolt or solder them, but in some cases this type of connection is unacceptable and you have to look for alternative options. Clay "Moment Crystal" is currently one of the leaders in this matter.

It contains special substances that improve adhesive properties and allow even the most slippery materials to stick to each other. This adhesive will not work for polyethylene and polypropylene, but otherwise it will work well for any composite polymers.

Glue composition

Each substance receives its properties from the interaction of its constituent components. Each adhesive is a mixture of a large number polyatomic chemical compounds that are processed in a certain way to make a finished product.

Transparent glue "Moment Crystal" consists of:

- heterochain polymers of the polyurethane group;
- ethyl ester of acetic acid;
- saturated ketones, in particular acetone;
- special additives for stabilization of chemical properties.

The structure of the substance is very complex, and the method of preparation requires careful creation of the conditions necessary for interaction. So it is not possible to make such glue at home on your own. The glue got its name for its crystallizing properties after solidification. It forms a very strong adhesive seam, which is not subject to the influence of most destructive factors. Often it will be much easier to break the product in another place than to do it along the seam.

Application area

Universal glue "Moment Crystal" can be purchased at the store building materials and many supermarkets. It is easy to find on the gray packaging. The material will cost a little more than the standard model, because it has additional properties. But it can also be used to join cardboard, rubber, ceramics, metal, wood, glass, paper, cork, foam rubber.

The substance is not suitable only for products in direct contact with food. You also need to take precautions when working with it. If part of the glue gets on the skin, you should immediately wash it off with plenty of warm water.

At hit of substance in eyes - at once to address to the doctor. Inhalation of glue vapors causes hallucinations, dizziness, and sometimes nausea and vomiting. And the ingress of a substance digestive system may lead to death. Therefore, you need to store the glue out of the reach of children and pets.

Main characteristics

Before buying, you should make sure that the glue is really suitable for the operation intended for it. The properties of a substance can be read below as detailed list with description:

1. It has a transparent color, both in a liquid and in a frozen state.
2. The polyurethane basis adds to it additional resistance to the destructive influence of atmospheric factors. Therefore, glue can be used, among other things, for products oriented to outdoor use.
3. Provides a high degree of adhesion of parts due to the crystallization of the seam.
4. It is characterized by water resistance, so it can be used to glue, for example, a rubber boat or boots, to repair shoes and other products that, due to their service life, have to periodically come into direct contact with water.
5. Can be stored for two years at temperatures from -20 to +30 degrees Celsius. The main condition for preservation is the tightness of the original packaging. Otherwise, the glue dries quickly and becomes unusable. You can bring it back to life after freezing by ordinary defrosting, but after it crystallizes, it remains only to throw it in the trash.
6. It burns well, so work should be carried out only away from open sources of fire. Can be used at temperatures up to 70 degrees.

Release form and price

The Moment Crystal glue is packed in 30 and 125 milliliter tubes. At the same time, options for completing a show box or a blister card are possible.
