Core Performance Advantages
First:
Deep Penetration & Reliable Sealing The product delivers excellent pore permeability and uniformly fills internal micro-pores of coatings. Under conventional working conditions, the effective penetration depth reaches 250–500 μm for alumina and chromia ceramic coatings, and 200–300 μm for tungsten carbide and other cemented carbide coatings, meeting the sealing requirements of most industrial thermal spray coatings. It supports natural penetration, vacuum-assisted penetration and immersion application methods for stable and consistent sealing performance.
Second:
Multi-Grade Temperature Resistance Coverage The full series covers a temperature resistance range from 350°C to 600°C with multiple graded models, matching long-term service temperature requirements of different working conditions. It provides targeted solutions from general medium-temperature corrosion protection to high-temperature condition reinforcement, adapting to diverse thermal spray application scenarios.
Third:
No Surface Film & Dimensionally Stable With a penetrating sealing formulation, it only fills internal pores of the coating without forming an extra continuous film on the workpiece surface. After sealing, the original appearance and surface morphology of the coating are maintained, and workpiece dimensional accuracy remains unchanged. No secondary grinding is required, and the surface roughness and assembly tolerance of the coating are not affected.
Fourth:
Comprehensive Coating Performance Enhancement After sealing, it effectively blocks corrosive media and conductive media from penetrating into the coating interior and substrate interface, significantly improving the coating's insulation, corrosion resistance, sealing performance, wear resistance and high temperature stability, and greatly extending the service life of workpieces under harsh conditions such as corrosion, electrification and high temperature.
Fifth:
Flexible Application AdaptabilityIt can be applied by brushing, spraying, immersion, vacuum impregnation and other methods, adapting to processing requirements of workpieces with different sizes and structures. The product features stable storage and simple operation, suitable for both industrial mass production and single-piece maintenance processing scenarios.
