High temperature resistant boiler漆
KF-BO100 Boiler High-Temperature Paint
KF-BO100 boiler-specific high-temperature resistant paint uses silicone-modified alkyd resin as a base material combined with heat-resistant and rust-proof pigments. The coating can withstand temperatures up to 350 degrees Celsius (450 degrees Celsius for short periods). It is resistant to sulfur-containing flue gas and high-temperature steam without peeling or chalking. It is widely used for high-temperature rust prevention and decorative coating of the exterior walls of various industrial boilers, power plant boilers, waste heat boilers, and thermal oil boilers.

Boiler-specific high-temperature resistant paint is a high-performance professional coating product developed and manufactured by Kexin New Materials. It is scientifically formulated with high-quality resins and imported pigments and fillers, exhibiting excellent adhesion, durability, and application performance. It is widely used in industrial manufacturing, architectural decoration, automotive, and other fields.
As a source coating manufacturer, Kexin New Materials strictly adheres to the ISO9001 quality management system in all aspects of its boiler-specific high-temperature resistant paint, from formulation design and raw material procurement to production and filling. The products are certified to environmental regulations such as RoHS and REACH. Free sample testing and on-site technical engineer guidance are provided.
Why choose boiler high-temperature paint?
CoreAdvantages
Boiler-grade boiler resistant to 350 degrees Celsius
The silicone-modified resin balances heat resistance and adhesion. It maintains a long-term temperature resistance of 350 degrees Celsius, meeting the typical surface temperature requirements of 200-300 degrees Celsius for boiler exteriors. It withstands short-term temperatures up to 450 degrees Celsius without failure, handling boiler start-up, shutdown, and peak operating conditions. The coating exhibits minimal high-temperature discoloration, consistently maintaining its aesthetic quality.
Sulfur-resistant and steam-resistant boiler environment
The coating is resistant to sulfur-containing flue gas (SO2/SO3) and does not corrode, preventing sulfate spots from forming. It resists high-temperature steam penetration without bubbling or peeling. The coating is resistant to hot oil/heat transfer oil splashing and does not soften. It is suitable for various flue gas environments in boilers using coal, oil, gas, biomass, and other fuels.
Bottom surface matching system protection
A complete coating system is formed by combining it with an inorganic zinc-rich or epoxy heat-resistant primer. The primer provides cathodic protection and adhesion, while the topcoat provides heat resistance and decorative properties. The coating system is designed for a service life of 8-12 years. Both roller coating and spray coating are suitable for large-area application with high efficiency.

Frequently AskedFAQ
ApplicationProcess
Surface preparation
Clean substrates thoroughly of oil and rust. Blast steel to Sa2.5. Pre-treat per product spec to keep the substrate clean. Ambient 5-40°C, relative humidity<85%。
Primer / pre-treatment
Select the matching primer or pre-treatment per substrate and system. Mix strictly at the stated ratio and control DFT. Proceed after the primer dries; pre-stripe critical areas.
Main-coat application
Apply the main coat per the process spec, strictly controlling DFT, temperature/humidity and flash-off to keep the film uniform without sagging or pinholes.
Curing process
Cure fully by stoving or by ambient air drying as the product requires. Keep oven temperature uniform within ±5°C and ramp up gradually to avoid coating defects. For ambient-curing grades, ensure adequate ventilation and suitable humidity.
Inspection & acceptance
Inspect all parameters: dry film thickness, adhesion, gloss, colour difference and chemical resistance. Full performance testing is carried out against the relevant standards. Only after everything passes are the test report and warranty issued, and the goods are packed and shipped in dust-free conditions.
