- Countertop
Installation and Sealing: It is a primary choice for sealing seams and
joints during the installation of natural and synthetic stone surfaces. - Stone
Compatibility: The adhesive provides excellent unprimed adhesion to common
substrates such as granite and marble. - Seamless
Bonding: It is available in a wide array of colors including clear white
black aluminum almond bronze and gray as well as specialized translucent
shades like trans white trans charcoal and trans beige to ensure a clean
color matched finish. - Backsplash
and Sink Sealing: Because it creates a waterproof seal and is resistant to
mold and mildew it is ideal for finishing the wet areas of a kitchen.
Food Service and Cold Storage
RTV4500A is highly valued in the food service industry due
to its rigorous safety certifications.
- Food
Safe Standards: The product meets the requirements of NSF Standard 51 and
FDA Regulation Number 21 CFR 177.2600 making it suitable for food grade
applications. - Walk
In Freezer Manufacturing: It is used extensively in the production and
installation of walk in coolers and freezers because it withstands extreme
cold. - Appliance
Manufacturing: It serves as a reliable sealant in the assembly of
residential and commercial kitchen appliances.
Industrial and HVAC Applications
The technical specifications of RTV4500A allow it to thrive
in heavy duty industrial environments.
- HVAC
Applications: It is frequently used for sealing ductwork and ventilation
systems. - Extreme
Temperature Resistance: The silicone remains effective in service
temperatures ranging from negative 70 degrees Fahrenheit to 400 degrees
Fahrenheit and can even handle intermittent exposure to temperatures
exceeding 400 degrees Fahrenheit. - Gasket
Creation: It is often used for formed in place gasket applications in
industrial manufacturing. - Sheet
Metal Work: It provides a strong flexible bond for sealing and joining
sheet metal components.
Transportation and Marine Use
Its resistance to UV and physical movement makes it ideal
for vehicles and marine vessels.
- RV and
Trailer Manufacturing: It is used to seal exterior seams on RVs and
trailers offering 25 percent joint movement capability to absorb the
stress of travel. - Marine
Applications: It is a trusted sealant for boat assembly and maintenance
where exposure to water and salt is constant.
Key Technical Advantages for Users
- Vertical
and Overhead Work: The non slump gun grade formulation prevents sagging
allowing for clean application on vertical joints and ceilings. - Fast
Skin Over: It forms a skin in approximately 10 minutes at room temperature
facilitating faster project completion. - Ease
of Use: As a one component product it requires no mixing or additives and
is easy to extrude even in cold temperatures.
