Rules for choosing heat-resistant glue for oven glass and instructions for use
If the integrity of the oven glass is broken, do not rush to change the entire device. Heat-resistant sealants help repair the device. In this case, it is worth paying attention to the choice of their composition. When using heat-resistant glue for oven glass, it is important to take into account that it must withstand temperatures above 260 degrees. The safety of the substance is not negligible, since it will come into contact with food.
Adhesive Requirements
Usually ovens have 2 or 3 glasses. They are heat resistant. However, over time they can be damaged due to constant temperature fluctuations. Sometimes there is a situation when constant exposure to high temperatures, ingress of grease, steam and detergents cause the original characteristics of the glass to be lost. As a result, it simply peels off.
Also, the cause of damage is mechanical impact - hitting with a heavy object, scratching or tilting the doors. At the same time, replacing the glass with the use of universal glue will not bring tangible results.
In order to repair the oven in such a situation, it is recommended to purchase a heat-resistant high-temperature adhesive.At the same time, it is important to choose the right composition, since most of these substances are not intended for contact with food. They release toxic elements. And this is possible not only when heated.
In any hardware store there are many effective substances. To choose the best quality product, you should focus on the following requirements:
- Plastic. When exposed to high temperatures, the glue should not crack.
- High degree of adhesion. The adhesion of two dissimilar surfaces must be reliable.
- Raincoat. The substance should be moisture resistant.
- Respect the environment. Glue for oven must necessarily meet this requirement. The substance comes into contact with food. Therefore, it should not release toxic elements.
- Moderately fast solidification.
To achieve the required strength, the adhesive must cure at room temperature.
What glue is suitable for oven glass
The main requirement for the choice of glue for the oven is resistance to temperature fluctuations. The substance should be elastic and non-toxic. Experts advise using several options for this glue. Most often for this purpose silicone sealants are used. To repair the oven, it is worth using glue with a specialized composition. One such substance is Dow Corning Q3-1566. It has the consistency of a paste, does not flow and does not lose its elasticity when exposed to temperatures from -50 to +275 degrees.
"RTV 118Q" is considered an effective remedy. The packaging indicates that the product can be used to repair food processing equipment. Another suitable formulation is LK glue.It ensures the fixing of different materials. In addition, the substance is able to withstand temperatures up to 1100 degrees.
Authorized products include Titan and Soudal sealants. The packaging says they can withstand temperatures up to 1500 degrees. Titanium is considered food grade.
Another effective composition is KLT-30 organosilicon sealant. It is made on the basis of rubber and can be used at temperatures from -55 to +250 degrees. The product is not affected by humidity. The label indicates that the composition is able to fix ceramics, glass and other materials.
Work instructions
To repair the device, follow these steps:
- To facilitate replacement, it is recommended to remove the oven door.
- Places where glue is planned to be applied must be thoroughly cleaned of carbon deposits and remnants of old glue.
- Carefully glue the fixing areas of the inner pane.
- Put the glass back in place and turn the door over, laying it on a flat, hard surface. In this case, it is important to ensure that the glass does not move away from the fixing area.
- Coat the bonding areas on the second side and install another pane.
- For reasons of reliability, it is allowed to use weighting materials.
- Wipe the squeezed glue with a towel.
- Go away for a day.
- Replace the door and begin operating the oven.
Review of popular brands
To fix the oven glass, it is worth using effective sealants. Several effective and safe formulations can be found on the market today.
Dow Corning 736
This putty can be used to fix surfaces that come into contact with food.It is allowed to be used at temperatures from -65 to 260 degrees. A slight overshoot of the parameters up to +315 degrees is allowed. The composition fixes metals and glass well. At a temperature of +23 degrees and a humidity of 50%, it dries in 17 minutes. The product is characterized by the acetoxy type of hardening. The acetic acid smell disappears in 24 hours. When applied, the composition does not flow.
"RTV 100", heat resistant silicone
This adhesive sealant is designed for high temperature use. The composition is able to withstand temperatures up to +343 degrees. It is sold in packs of 85 grams. The product hardens in one hour. However, it takes a day to completely dry.
With the help of the substance it is possible to achieve reliable tightness. The composition is resistant to various technical fluids, with the exception of gasoline. It is also characterized by resistance to ultraviolet radiation. The composition can come into contact with food and water. They can bond metal surfaces, glass, ceramics. Solidification of the substance occurs at room temperature.
Kraftool Kraftflex FR150
It is a refractory silicate product that can withstand temperatures up to 1500 degrees. With its help, it is allowed to glue tiles, metal, stone. The product is resistant to chemicals. After solidification, it is possible to obtain a monolithic surface. The glue is odorless.
To repair the furnace, it is recommended to use sealants in the tubes, since a construction gun is needed to use tubes weighing 300 grams. The oven glue must be safe and have a high degree of adhesion. To achieve reliable fastening, the rules for carrying out repair work should be strictly followed.
