Moment Kristall waterproof polyurethane is one of the many adhesives produced by Henkel. The products of this enterprise are well known all over the world, and production facilities are located in many countries. In Russia, the production of Moment glue is handled by Henkel Era LLC, located in the city of Tosno, Leningrad Region, and has been operating as part of the concern since 1991.
The Moment Crystal glue contains stabilizing agents, heterochain polymers of the polyurethane group, ethyl acetate and acetone. Due to the presence of these components, the adhesive is highly water resistant and suitable for use in environments with high humidity. The product is absolutely transparent, as a result of which the junction of the elements is practically invisible. In the process of drying, the composition crystallizes, which ensures a high degree of adhesion of the parts and guarantees the durability of the connection. The adhesive is highly heat- and frost-resistant and tolerates well the action of alkalis and dilute acids.
Glued things can be used at temperatures from -40 to 70 degrees without the risk of deformation of the seam or mutual displacement of parts. The optimal temperature range for installation work is considered to be a range of plus 18-25 degrees, but if necessary, gluing can be carried out both at lower and at higher temperatures.
If the work with the composition is carried out under extreme conditions, it must be borne in mind that the drying of the glue completely depends on the evaporation time of the solvent. The slower this process takes place, the longer it will take for the joint to fully polymerize.
"Moment Crystal", like many other compounds in this category, is a flammable substance. Therefore, bonding work should be carried out away from sources of open fire and with good ventilation if installation is carried out indoors. The density of the glue is 0.88 g / cm3, and the average consumption, provided that the composition is applied to both surfaces, varies from 250 to 350 g / m2. The product can be stored at temperatures from -20 to 30 degrees and, if frozen, quickly restores its properties after thawing. The shelf life of the glue is limited to two years, provided that the storage temperature is observed. The form of release of the glue is presented in tubes of 30 and 125 ml, as well as in cans with capacities of 750 ml and ten-liter canisters.
Advantages and disadvantages
A large number of positive reviews and high consumer demand for Moment Crystal glue due to a number of its indisputable advantages:
- comfortable cost and affordability make the product very popular in everyday life and household;
- increased strength and durability of the connection allow the use of glue for working with parts subject to moderate mechanical and vibration stress;
- the absolute transparency of the butt joint explains the widespread use of glue for repairing home furnishings and souvenirs;
- the possibility of combination gluing, which allows you to connect materials in various combinations, significantly expands the scope of the composition and makes it even more popular;
- the glue does not contain toluene, therefore, the use of the composition for other purposes is excluded.
The disadvantages of the "Moment Crystal" composition include restrictions on gluing objects in contact with food, and an unpleasant odor due to the presence of a solvent in the composition.
Scope of application
Moment Crystal glue is widely used in all spheres of economic activity. The tool is suitable for connecting materials of different structure and density to each other in any combination. With this versatile compound, you can glue porcelain, ceramics, plexiglass, fabric, rubber, foam, cork and paper in different versions. Due to its high waterproof qualities, the glue is successfully used in the repair of inflatable boats, country pools and footwear.
Despite the wide range of materials that perfectly adhere with the help of "Kristall", there are a number of restrictions on the use of this tool. The main one is the impossibility of working with utensils and other objects that have direct contact with food. The glue is also not suitable for bonding Teflon, polyethylene and polypropylene parts.
Instructions for use
In order for the gluing to be strong and durable, it is necessary to adhere to a number of rules that can be found in the description of the product on the package. The main guarantee of the strength of the connection is the careful preparation of the working bases. To do this, both surfaces must be cleaned of mechanical contamination, dust must be removed and must be degreased with gasoline or acetone. After the bases are ready, you should carefully open the tube, holding it in an upright position. This will help prevent glue from spreading and keep your hands and packaging clean.
Next, you need to apply the gel to both surfaces and leave for 10-15 minutes. If the material has a porous structure and quickly absorbs the composition, the application should be repeated. After the specified time has elapsed, it is necessary to forcefully connect the parts to be glued and hold them in this position for several seconds.
At the moment of connecting parts to each other, it is possible to adjust their location, which is very important when gluing interior items and souvenirs. After a day, the product is completely ready for use.
When working with Moment Crystal glue, one should not forget about personal safety measures. The product belongs to the class of flammable materials, therefore its use near open fire is strictly prohibited. Before starting work, you must open the vents or turn on the ventilation. In the process of working with glue, it is important not to allow it to get on the skin of the hands and the mucous membrane of the eyes. In case of accidental contact, the skin should be rinsed with plenty of warm water. Store the Moment package out of the reach of children and animals. Clean tools from glue with gasoline immediately after finishing work. In case of contact with the fabric, the product is recommended to be dry-cleaned.
Due to its high quality, ease of use and low cost, "Moment Crystal" is practically unmatched in its category of adhesives. Being an indispensable assistant in the household and everyday life, it allows you to quickly and efficiently repair any product and extend the life of your favorite things.
