When repairing car glass, inserting headlights ormirrors special compositions are required. Until recently, epoxy adhesives have been used for this, and today more robust compounds are used to firmly bond the auto components. How to choose the glue for automotive glass? Which brand products should be preferred?
Automotive adhesive is a universal tool,which can be used with any glass and optical components. Its structure and composition ensure tight adhesion of surfaces and sealing of joints. At the same time, the means differ in safety and in the absence of harmful substances.
Клей для автомобильного стекла чаще всего имеет Polyurethane base, which provides good adhesion. Glutinous sealants are often used when gluing auto glass, headlights and any other optical components.
When buying a product, you need to pay attention toavailability of a quality certificate from the seller. A mandatory condition for quality glue is compliance with those parameters that are written on the package. The product must meet certain requirements:
Today you can buy polyurethane adhesives of various brands. We suggest you evaluate the products of the most popular brands with a description of their main characteristics and advantages.
Modern adhesives can be used both forrepair cars, and when they are manufactured, when the glass is installed. When installing a windshield or rear window, it is important that the joints are sealed and resilient, since they will be heavily loaded. The glue is applied to the dark areas of the glass, since the composition is not well protected from sunlight. In reviews about the glue for automotive glass, Terostat products are often mentioned, which has good adhesion to surfaces.
But in the line of other brands you can findMeans that are distinguished by good resistance, retention ability and rapid setting. For repair, so-called optical adhesives are used that are resistant to sunlight and quickly restore the optical properties of the surface. Separate attention deserves the ultraviolet adhesive, which freezes only under the sun's rays. Use of such compounds can be done on metal surfaces.
The gluing of the glass is carried out according to two technologies- Primary and non-primitive. The first involves the use of a special primer - black primer, which is applied on the edge of the glass. Already it is applied to the activator and the glue, after which the glass is fixed in the frame. Such technology used to be used in many service centers, and today the masters use a more modern method - the gluing of automobile glasses without a primer.
This was made possible by the production ofa protective strip, which is applied by silk-screen printing. And the primer is replaced with a colorless activator, which can be applied to the metal or the remains of the old sealant. Without the activator can not do - it is needed to improve the adhesion to the primer.
How to glue car glass, if theycrashed or cracked? The brand LIQUI MOLY offers a whole line of single- and two-component compounds that quickly harden under the influence of moisture. Glue sealants of this brand are ideal for gluing any glass in a car, and the process is performed in just 2 hours. In addition to the average strength, the adhesive is characterized by high viscosity and excellent quality.
Используя клей LIQUI MOLY 1400, можно быстро make a gluing of the glass, and after a few hours to use the car. It is applied to the body opening, which is carefully leveled and cleaned beforehand.
Under this brand is produced quality adhesive forrepair of automotive glass, which quickly hardens under the influence of moisture. The glasses are ready for use after 2 hours. The composition is based on polyurethane, which has a high retention ability at any humidity and temperature. Sealant is widely used for gluing wind, side, rear windows of cars, both cargo and passenger cars. Pasty consistency affects the rapid application and hardening.
Adhesive sealant for automotive glass Terostatapplied to a dry, cleaned of oil, dust, grease surface. First Primer-8510 is applied using an applicator, after which it is given 15 minutes for complete drying. When inserting glasses already covered with glue, an activator is used. It is needed to ensure good adhesion and is applied in a thin layer. The latest stage is the application of the sealant by hand with the help of some tools.
For professional pasting automotiveglasses require quality compounds. Betaseal brand produces glue for automotive glass, which prevents the loss of windshield, ensures correct operation of airbags, prevents deformation of the roof. Due to the rigidity of the fastening, the windshield and the body of the vehicle are firmly held together. In favor of the choice of compositions with a polyurethane base, the following characteristics are said:
Due to its good moisture resistance and viscosity, high shear modulus and low specific resistance, the windshield is fully integrated with the body.
Glue for gluing of automobile glasses Dinitrol -this is a universal tool with polyurethane base, which, thanks to its good consistency, easily and quickly fills all the gaps and freezes under the influence of external moisture. Use of this composition is advisable with direct gluing of glasses during repair or production of vehicles. Good viscosity in combination with the application on a qualitatively prepared surface ensures the reliability of the adhesive bond. The most popular composition in the line of the brand is the Dinitrol 500, which differs:
The reviews mention that Dinitrol formulations should be used with preliminary surface preparation, which implies treatment with primer and activators.
Wurth products have proven themselvesA reliable tool for gluing rear-view mirrors, parts to rotary glasses and gluing glass. In the range of sealants of different types, which are easy to use, quick installation due to good adhesion, the resistance of adhesive bonding to shock loads or vibrations.
Adhesive for gluing of automobile glasses WurthIt is tested for safety in laboratories in Germany and approved by the leading manufacturers of vehicles. As with other similar products, cleaning and degreasing of surfaces is mandatory before glue application. This will increase the adhesion and improve the performance properties of the formulation.
The article describes the most popular types of sealants manufactured by leading manufacturers. All of them are equally effective and easy to use, so there will be no problems with the replacement of the car glass.
