Which glue for automotive glass?

When repairing the car's glass, inserting headlights or mirrors, special compounds 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 I prefer?

Features of formulations

Car glue is a versatile tool that can be used with any glass and optical components. Its structure and composition ensure dense adhesion of surfaces and sealing of joints. At the same time, the means differ in safety and in the absence of harmful substances.

The glue for automotive glass most often has a polyurethane backing that provides good adhesion. Glutinous sealants are often used when gluing auto glass, headlights and any other optical components.

Selection rules

When buying a product, you need to pay attention to the availability of a quality certificate from the seller. The obligatory condition of quality glue is compliance with those parameters that are written on the package. The product must meet certain requirements:

• Elasticity, which is needed to compensate for the temperature difference - it occurs between the glass and the metal when the composition is expanded;
• Strength: the glue for automotive glass should form a strong seam so that the glass does not fly out in emergencies;
• Modularity: this characteristic helps to qualitatively glue the details of the car so that there is no vibration while driving, and the vehicle itself was more manageable;
• Electrical conductivity: it is necessary in order to avoid the driver's contact with the parasitic current.

Today you can buy polyurethane adhesives of different brands. We offer you to evaluate the products of the most popular brands with a description of their main characteristics and advantages.

For repair or installation of glasses

Modern adhesives can be used both for car repairs and for their production, when glass is installed. When installing a windshield or rear window, it is important that the joints are sealed and resilient, since they will have a heavy load on them. The glue is applied to the dark areas of the glass, since the composition does not have good protection 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 find tools that have good resistance, retention ability and quick grasping. 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 glue, which freezes only under the sun's rays. Use of such compounds can also be done on metal surfaces.

About gluing technologies

The gluing of the glasses is carried out using two technologies - primer and non-priming. 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 glue, after which the glass is fixed in the frame. Such technology was used before in many service centers, and today the masters use a more modern method - gluing of automobile glasses without a primer.

This became possible thanks to the production of glasses with a protective strip, which is applied by silk-screen printing. A 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.

LIQUI MOLY

How to glue car glass, if they crashed 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.

Using the adhesive LIQUI MOLY 1400, you can quickly paste 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.

Terostat

Under this brand is produced a quality adhesive for the repair 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.

Glue-sealant for automotive glass Terostat is applied to a dry, cleaned from oil, dust, grease surface. First Primer-8510 is applied using an applicator, after which it is given for 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 glue-sealant by hand using some tools.

Betaseal

For professional gluing of automotive glasses, quality compounds are required. 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 choosing the compositions with a polyurethane base, the following characteristics are said:

• High level of elasticity;
• Good adhesion with a painted surface;
• High polymerization rates;
• Resistance to sunlight and deformation.

Due to its good moisture resistance and viscosity, high shear modulus and low specific resistance, the windshield is fully integrated with the body.

FC Kit Dinitrol

Glue for gluing of automobile glasses Dinitrol is a universal tool with a polyurethane basis which, thanks to a successful consistency, easily and quickly fills all gaps and under the influence of external moisture freezes. 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 brand's lineup is the Dinitrol 500, which differs:

• Good adhesion with paintwork;
• Absence of smell;
• Good performance;
• Good shape stability properties;
• High elasticity.

In the reviews it is mentioned that it is necessary to use Dinitrol formulations with preliminary preparation of surfaces, which involves primer and activator treatment.

Wurth

Wurth products have proven themselves as a 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.

The glue for gluing of automobile glass Wurth is tested for safety in laboratories of Germany and approved by 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.
