KINGDELI High Temperature Silicone Sealant - Heat-Resistant Solutions
High Temperature Silicone Sealant
Features & Benefits
KINGDELI high temperature silicone sealant offers exceptional thermal stability, long-term elasticity, and superior adhesion to metals, ceramics, glass, and specialty substrates. Formulated for continuous exposure to elevated temperatures, our sealants resist thermal cycling, ozone, and weathering while maintaining low-VOC performance for safer indoor and industrial use.
High-Temperature Performance
Engineered to withstand sustained heat and intermittent peak temperatures, this sealant ensures reliable sealing and bonding where conventional silicones fail. Typical service ranges and peak temperature tolerances are optimized for oven, furnace, engine, and high-temperature enclosure applications, providing leak-proof protection and electrical insulation where it matters most.
Applications
Designed for industrial, automotive, HVAC, electrical, and manufacturing settings, KINGDELI high temperature silicone sealant is ideal for gasketing, flange sealing, exhaust systems, heating elements, and high-temp potting. Versatile adhesion and non-corrosive formulations make it suitable for both assembly lines and on-site repairs across multiple industries.

Will HY922 corrode metal substrates?
No. The formulation is non-corrosive and safe for use on metals such as aluminum and steel, as well as non-metal substrates.
Is the cured grout flexible?
Yes. HY951 maintains a certain level of flexibility after curing, helping it accommodate minor movement and improving long-term durability.
Can HY-972 be painted over?
Yes. Once fully cured, HY-972 can be painted with most water-based paints.
What surfaces and applications is HY-726 NOT recommended for?
While HY-726 is highly versatile, it is generally not recommended for the following:
Structural glazing applications where high-modulus, load-bearing sealants are required.
Surfaces that require paint application over the sealant, as silicone does not accept paint.
Porous natural stones such as marble or granite without proper testing, as silicone may cause staining.
Submerged or continuously immersed surfaces such as aquariums or swimming pools, unless specifically tested for such conditions.
Always conduct a compatibility test on a small, inconspicuous area before full application on any new or sensitive surface.
What temperature range can HY-723 withstand?
It maintains stable performance in extreme temperatures ranging from -50℃ to 200℃.
