Oven Boiler Neutral Silicone Sealant is a single-component neutral-curing high-temperature sealant purpose-built for the sealing needs of ovens, boilers, industrial heating furnaces and high-temperature pipelines. It uses high-purity silicone polymer as the core base material, compounded with high-temperature resistant ceramic fillers and environmentally friendly curing agents, forming a non-corrosive neutral curing system that releases no acidic corrosive gases during the curing process. No premixing is required before construction; it can be directly extruded for use at room temperature, with fast skin-forming time to improve construction efficiency. It has excellent adhesion to stainless steel, cast iron, galvanized sheets, ceramics, tempered glass and other common substrates for thermal equipment, and will not cause corrosion, oxidation or discoloration to metal substrates.

This product achieves a comprehensive upgrade in core performance compared with ordinary silicone sealants. It maintains stable elastic performance in the long-term working temperature range of -50℃ to 300℃, and can withstand instantaneous thermal shock up to 350℃ without melting, cracking, powdering or losing adhesion. After fully cured, it forms a high-density cross-linked elastic sealing body with a tensile bond strength of ≥0.8MPa and excellent displacement compensation ability, which can flexibly adapt to the thermal expansion and contraction deformation caused by frequent start-stop of heating equipment, and always maintain a tight sealing structure. It also has excellent resistance to water vapor, oil fume and weather aging, and can maintain stable sealing performance for a long time under the complex working conditions of high humidity, heavy oil stain and periodic high temperature, making it suitable for oven door gaps, boiler flange joints, high-temperature pipeline seams and other key sealing positions.

Oven Boiler Neutral Silicone Sealant directly addresses the common pain points of high-temperature equipment sealing in daily operation and maintenance. Its durable high-temperature resistance avoids frequent rework and glue replacement caused by seal cracking and debonding, reduces equipment shutdown maintenance time, and effectively lowers comprehensive operation and maintenance costs. The neutral formula will not corrode the precision metal parts and enamel liners of ovens and boilers, effectively protecting the equipment substrate from damage and prolonging the overall service life of the equipment. With excellent air tightness and water tightness, it can effectively prevent heat loss, steam leakage and oil fume overflow, improve the thermal efficiency of the equipment, and eliminate potential safety hazards such as steam scalding and oil fume leakage in the working environment.

All performance indicators of the product have been verified by professional third-party testing. Its high-temperature resistance and bonding performance fully comply with the requirements of GB/T 14683-2017 standard for building and industrial silicone sealants, and it still maintains stable bonding performance after 168 hours of high-temperature aging test at 250℃. The product formula meets ROHS environmental protection requirements, does not contain harmful substances such as formaldehyde and heavy metals, and is safe for use in food-related oven equipment scenarios. With strict full-process production control and 100% factory inspection, Oven Boiler Neutral Silicone Sealant provides a reliable and long-lasting sealing solution for all kinds of high-temperature thermal equipment.
