High Temperature Sealant
High temperature sealant is essential for many applications. It is designed to hold up against high temperatures and other harsh conditions that normal sealants can’t.
Choose the right high temperature sealant for your application by understanding what you need it to do. Some factors to consider are the temperature range it must withstand, fire resistance and flexibility.
Heat Resistant
Heat resistant sealants, also known as high temperature silicone or caulk, are specifically designed to withstand extreme temperatures without losing their strength or flexibility. They have a much higher melting point than regular sealants and are often used in applications such as electrical insulation or the sealing of joints, cracks or gaps in areas exposed to continuous vibration or extreme heat.
Choosing the right heat resistant adhesive for your application can be tricky. You will need to determine the maximum and minimum temperature that the area is likely to experience as well as the type of chemical and moisture resistance you require. Some heat resistant silicones can be used as both an adhesive and a sealant, while others may only be suitable for use as a sealant. Before purchasing a product, make sure that it is clearly labelled as a heat resistant or high temperature silicone and not just a general silicone.
Vitcas(r) heat resistant sealant is a ready mixed high temperature sealing and caulking paste which can be applied to a wide variety of surfaces including ceramics, glass, metal and other silica based materials. It is able to withstand up to 1300oC and offers good adhesion and gap filing properties. It is ideal for a range of applications such as sealing or fixing ceramics, glass and metal and can be used in both indoor and outdoor environments.
Fire Retardant
Fire retardant high temperature sealant is a great solution for areas that need to resist the spread of flames, smoke and gases. This type of silicone sealant is typically odourless, safe to use and adheres to a wide range of materials including metal, glass, plastic and wood. It is also able to withstand harsh chemicals, weather and vibration. It is available in a variety of sizes and colors so you can find the right one for your project.
A fire resistant silicone sealant is designed to be used as a filler high temperature sealant or bonding agent for applications such as sealing seams and joints in fireplaces, ovens, stoves and flues. It intumesces when exposed to a fire, blocking the passage of flames, smoke and toxic gases. It is suitable for use in residential and commercial applications.
When applying a fire resistant high temperature sealant, be sure to follow the manufacturer’s instructions for application. It is important to high temperature sealant clean the surface before using, and to allow the sealant to cure completely before placing weight on it. You should also avoid exposing the sealant to direct sunlight, as it may crack or break if it is subjected to intense heat for prolonged periods of time. A fire-resistant sealant can be purchased online or at a hardware store. It is recommended that you purchase a high-quality brand from a reputable manufacturer or supplier that can provide warranty coverage on their products.
Chemical Resistant
There are different types of high temperature silicone sealant available depending on the level of flexibility and durability you need. Some can withstand extremely hot temperatures, while others are more flexible and better suited for areas that expand and contract often. You can also choose from a range of colours to match the look of your project.
For example, a red coloured acetic cure silicone can be used in sanitary applications such as sealing baths and showers, though it is also highly durable. It is resistant to mildew, will not crack or discolour and can withstand temperatures of up to 204degC continuous. This sealant is very strong and elastic with a breaking elongation of over 300%.
Another good choice is a black industrial silicone. It can be used in a variety of industrial projects including sealing stove and furnace vent pipes, encapsulating heating elements, moving oven belts, sealing bag filters on smokestacks and more. This high-temperature silicone has a resistance to oils, gasses and other chemicals, while still providing an excellent grip on surfaces and is unaffected by extreme temperatures. It is non-slumping and can be painted or sanded once it has fully cured.
Easy to Apply
High-temperature silicone sealants are easy to apply. They can be used to seal and encapsulate any number of materials, including glass, enamels, and smooth metals. They are also resistant to aging, vibrations, and shock. They are also easy to clean up after application. These types of sealants work well for sealing gaps, seams, and cracks around appliances, heating vents, and furnaces.
When applying a high-temperature sealant, it is important to follow safety guidelines. Always wear protective eye-wear, and avoid letting the adhesive come into contact with your skin. Additionally, it is best to take breaks while working with this product, as it can produce dangerous fumes. Additionally, you should never mix the product with other chemicals.
A good way to protect your hands while applying the product is to use a caulking gun. This will allow you to push the sealant ahead of the nozzle without straining or hurting your hands. After the sealant has been applied, it will dry to the touch within 30 minutes and will be fully cured within 24 hours. This makes it a great choice for many different household projects, such as sealing the edges of a ceramic hot plate, repairing cracks around windows, or closing up the gap around heating vents and doors. This will help you reduce energy costs by keeping heat in and cold out.
