Car glass sealant
Content
Car glass sealant not only securely fastens the glass to the car body in a variety of operating conditions, but also provides normal visibility, prevents moisture from penetrating into the passenger compartment at the attachment points, and also provides elasticity between the glass and the frame, which is necessary in conditions of vibration and / or deformation of the pillars.
Sealants for machine glass are divided into two main groups - repair and assembly. Repairs are also divided into five basic categories - balsam, balsam, balsam M, ultraviolet and acrylic adhesives. In turn, adhesive (mounting) compositions are divided into four groups - fast-acting polyurethane, one-component polyurethane, silicone and sealant adhesives. Each product belonging to a particular group has individual properties, so before you buy a sealant for gluing glasses, you need to figure out their purpose and where exactly they can be used. The rating of the best sealants will help you make the right choice.

How to choose the best glass sealant
Despite all the variety of these tools, there are a number of criteria by which you can choose the most suitable sealant, which will be the best in a particular case. So, these criteria are:
- High sealing properties. This is an obvious requirement, due to the fact that the product should not allow even the slightest moisture to pass through the seam between the glass and the body.
- Resistance to external factors. namely, do not change their properties at high humidity, do not crumble at negative temperatures, do not blur at high temperatures.
- Ensuring the elasticity of fastening. Ideally, the adhesive sealant for car windows should not only securely hold the glass, but also provide elasticity at the points of its attachment, that is, along the seam. This is necessary so that the glass does not deform during vibration, which always accompanies the car in motion, as well as when the body is deformed (due to an accident or just over time).
- Chemical resistance. namely, we are talking about car chemicals - shampoos, cleaning products, from the windshield and washing the body.
- Ease of use. This applies to both the shape and type of packaging, and the absence of the need to prepare additional formulations. Sealant for gluing car windows must be completely ready for use.
- High degree of adhesion. The product should adhere well to metal, glass, sealing rubber. it is also good if the sealant is sufficiently viscous, this ensures the convenience of application and work in general.
- Short curing time. And at the same time ensuring all the above requirements. However, this condition is rather desirable than obligatory, since whatever it may be, after gluing the glass, the car must be immovable for at least a day.
Some drivers make the mistake of using headlight sealant when installing the windshield. There are several other requirements for these funds, and one of the main ones is its high moisture resistance. This is due to the fact that the headlight does not sweat from the inside in wet weather, and not harmless to metal, elasticity and the ability to withstand heavy loads.
In addition to the factors listed above, you also need to decide on the following goals to be pursued:
- Glass size. namely, it is necessary to install glass on an ordinary passenger car or on a truck / bus, in which the length of the “front” perimeter is much larger. In this vein, two aspects are important - the size of the package, as well as the film formation time.
- Features of the body. The design of some modern cars assumes that part of the load-bearing forces of the body falls on the windshield and rear windows. Accordingly, the adhesive on which they are held must also meet these requirements, namely, to have high rigidity.
Each manufacturer has its own product line, which includes sealants with different characteristics.
Types of sealants for glass bonding
As mentioned above, windshield sealants are divided into 2 large groups - repair and installation. As the name implies, with the help of repair tools, you can make minor repairs to glass, such as a crack or chip. Mounting are designed to fix the glass in its seat. However, some mounting tools can also be used as repair tools. in order to clarify and protect car owners from buying inappropriate products, we list their types.
So, repair tools include:
- Balm for machine glasses. This tool is specifically designed for gluing glass surfaces, so it can be used to repair the corresponding damaged surfaces.
- Balsam. Intended for repair gluing work. namely, it has good polymerization, resistance to external factors. However, it has a significant drawback - after solidification, it forms a yellow spot on the glass.
- Balsam M. A tool similar to the previous one, but without the mentioned drawback, that is, after hardening it remains transparent.
- UV glue. With it, you can close the longest cracks. It has high performance characteristics - strength, fast polymerization. However, the disadvantage is that it requires exposure to ultraviolet rays to ensure its curing. In the simplest version - under the influence of bright sunlight. But it is better to use a special ultraviolet lamp.
- acrylic adhesive. A great option for self-repair on a glass surface. The only drawback is the long polymerization time, which can be from 48 to 72 hours.
Accordingly, the means listed above are not suitable if the car enthusiast plans to re-install the glass. To do this, you need to use sealants, which are divided into the following types:
- Fast acting polyurethane. Used in vehicles equipped with airbags. Very easy to use, has a short drying time, durable, but provides the necessary flexibility of fastening.
- One-component polyurethane. The effectiveness of the tool can be attributed to the average. It is universal, the market is widely represented by various samples.
- Silicone. Perfectly isolate moisture, are steady against vibrations and influence of an ultraviolet. Leaking silicone sealant can also be used to repair car windows. The disadvantage of silicone formulations is that they lose their properties when exposed to fuel and oil formulations (gasoline, diesel fuel, motor oils).
- Anaerobic. These sealants provide very high bonding strength while drying in a very short time. However, their disadvantage is the lack of elasticity, which can be detrimental to glass and pillars when frequently driven on rough roads, especially at high speeds.
Many motorists are interested in the question of how long the glass sealant dries? The relevant information is indicated in the instructions on the packaging of a specific product. Usually this time is measured in several hours. However, it is important to understand that sealants that cure longer provide better performance because they form stronger molecular bonds during the polymerization process. Therefore, it is worth buying a quick-drying agent only when repairs need to be made in a short time.
also one interesting question - how much sealant is needed to glue one windshield on an average passenger car. Here you need to understand that this value depends on many factors, such as the size of the glass, its shape, the thickness of the glass, the thickness of the sealant layer, and even the fact that the glass is part of a load-bearing body. However, on average, the corresponding value is in the range from 300 to 600 ml, that is, one cartridge for the gun should be enough to install glass in medium conditions.
What kind of sealant to glue the glass
Domestic drivers and craftsmen use a number of the most popular, effective and inexpensive sealants for car windows. Below is their ranking based on reviews and tests found on the internet. It is not advertising. If you have used any of the above or other means - write about your experience in the comments. Everyone will be interested.
