Heat Resistant Silicone Adhesive

Heat Resistant Silicone Adhesive

Many industrial applications require adhesives that are durable and can withstand high temperatures. Silicone is a reliable choice that can keep its elastic properties under extreme conditions.

There are both one component and two-part silicone systems available with a variety of curing mechanisms. Some systems are UV or radiation cured.


A key feature that sets silicone adhesives apart from most other types of adhesives is their ability to retain their elastic properties over a large range of temperatures. This flexibility is particularly important for many industrial applications where components can be subjected to a variety of stressful and demanding environmental conditions.

The specific range of temperature tolerance that silicone adhesives can withstand depends on the type of silicone used heat resistant silicone adhesive and the environment in which it will be used. For example, some silicones can resist high temperatures, while others can withstand exposure to UV rays.

Silicones are made from natural materials, so they have very little impact on the environment. They are also non-chemical reactive, making them an environmentally safe choice for a wide variety of applications.

Whether an application requires heat resistance or simply the ability to withstand high humidity levels, there is a suitable silicone for the job. For example, one-part acetic cure silicones are ideal for sealing, bonding and glazing while neutral cure silicones can be used in a wide range of construction, automotive and marine applications.

For example, Dow DOWSIL 736 Heat Resistant Sealant Red is a one component, non-slumping, acetic-cure silicone paste that withstands up to 180oC and can be used in a variety of applications. It is used in automobiles to glue parts and connections that are exposed to high temperatures and vibration, such as valve covers, water pump seals, axle housings and engine gaskets for forced induction systems.


Heat resistant silicone adhesives are thicker than typical sealants and thus have more structural strength. They also have a lower thermal conductivity than other adhesives, meaning that they don’t melt as easily under intense heat. Because of these characteristics, they are ideal for use in areas that are constantly exposed to high temperatures.

There are a number of different types of heat resistant silicone, each with its own specific set of strengths and properties. For example, there are those that can withstand temperatures up to 600 degrees Fahrenheit when cured, while others have better resistance to shocks and vibrations. Some have an NSF certification and can be used in foodservice applications, while others are designed to resist weathering and aging.

Some kinds of heat resistant silicone are made with an acid-cure that works well on non-porous surfaces like glass and glazed tile, as well as impregnated and painted wood. There are also neutral-cure silicones that are more versatile and can be used on a variety of materials, including ferrous and non-ferrous metals, concrete, brick, gypsum plasterboards and some plastics.

There are also specialist types of silicone that are formulated for automotive applications and can withstand the extreme heat generated by hot engine conditions. These types of silicone are often used on valve covers, water and oil pump seals, axle housings, fuel pump seals and ductwork. They can also be used in aerospace applications, such as bonding the light housings on airplanes.


The durability of silicone adhesives is a key factor that makes them the preferred choice for many industrial applications. These materials are designed to withstand rigorous and stressful conditions that could damage other bonding materials. They are also non-chemical reactive, which emphasizes environmental safety. When engineers are planning a project, they must consider all the elements of the design and determine how it will stand up to real world use.

Most traditional adhesives emit toxic fumes that can harm workers or cause health problems for the surrounding environment. Silicone adhesives, on the other hand, produce very little odor and have no negative effects on the surroundings. These materials are also easy to heat resistant silicone adhesive apply and don’t require specialized equipment. Whether you need to adhere a small piece of machinery or seal a large building, you can do it easily with silicone adhesive.

Liquid silicone rubber is available in a variety of formulations and curing times to meet different needs. It can withstand high temperatures and adhere to a variety of surfaces. You can choose between low and high modulus silicones based on how much movement you need. Acetoxy silicones release vinegar-smelling acetic acid during the curing process and are more rigid, while neutral cure silicones don’t smell and adhere to a wide range of materials. Choose a formulation that fits your needs and budget.

Resistance to UV rays

Silicone adhesives have a great resistance to UV rays, which makes them suitable for bonding items that will be exposed to sunlight. This feature is important in industries that work with materials that are subject to UV light, such as printing and textiles. It can also be beneficial in industries that deal with materials that are sensitive to light, such as electronics.

A heat resistant silicone adhesive is a non-toxic, chemically inert glue that is used to join and seal parts and surfaces that are exposed to high temperatures. It has great elasticity, which allows it to stretch and contract while remaining strong. It is also water repellent, which protects the bond from moisture and other contaminants that can affect its strength.

There are many varieties of silicone adhesives, each with its own benefits. Some are available in one component systems that require no mixing, while others are two part and require a curing agent to function properly. Other types include UV and EB radiation curing silicone adhesives, which cure with exposure to ultraviolet light, or pressure sensitive versions that adhere to surfaces under slight contact pressure.

Ceramic material is a tough, resilient substance that engineers rely on in numerous applications. It has exceptional strength and durability, and can withstand high temperatures for extended periods of time. The ability of heat resistant silicone adhesives to adhere to ceramic material is a major benefit in the use of these products.
