1500# black silicon carbide micro‑powder is an ultra‑fine hard filler specially for pipe wear‑resistant and anti‑corrosion coatings. Featuring fine and uniform particles, high purity and low impurities, it forms dense and smooth coating films to avoid scale buildup and pipe blockage. Its ultra‑high hardness effectively combats high‑velocity erosion caused by fluid, sediment and ore pulp.
With outstanding chemical stability, it delivers resistance to acid, alkali and salt spray as well as anti‑seepage and anti‑corrosion performance.
Boasting good powder dispersibility and excellent workability, it is compatible with various spray‑applied wear‑resistant and anti‑corrosion coatings for pipe inner walls and greatly extends the overall service life of pipelines.

Ultra‑fine 1500‑mesh fineness for dense, smooth paint film without pipe blockage
Compared with coarser 700# and 1000# powders, 1500# features finer particles and superior filling capacity, which fully seals micro‑pores in paint films. It produces flat and smooth film surfaces free of particle protrusions, preventing rough pipe inner walls, material accumulation and scale deposition. It fully meets inner‑wall coating requirements of fluid transmission pipes, mortar pipes and desulfurization pipes.
Ultra‑high hardness against slurry erosion and particle abrasion
Hard silicon carbide particles build a dense wear‑resistant skeleton within epoxy, polyurethane and ceramic composite coatings. It withstands long‑term high‑speed scouring from ore pulp, sediment, dust and acid‑base fluids, substantially prolonging pipeline service life and solving common pipeline failures such as surface sanding, abrasion, wall thinning and perforation.
Superior chemical inertness for heavy‑duty anti‑corrosion with acid, alkali and salt‑spray resistance
Black silicon carbide is insoluble in acids and alkalis, non‑oxidizable and non‑corrosive. It maintains stable performance under humid, high‑temperature and acid‑alkali working conditions. It remarkably improves the anti‑seepage, rust‑proof and anti‑corrosion performance of pipe coatings, ideal for heavy‑duty anti‑corrosion systems of desulfurization pipes, chemical pipes, sewage pipes and tailing pipes.
Good dispersibility and leveling property for spraying, brushing and rolling application
The 1500# ultra‑fine powder has excellent suspension property with little sedimentation and agglomeration. It disperses evenly in resin systems, reduces coating viscosity and improves leveling performance. It ensures smooth application and uniform, full films, suitable for large‑scale industrial coating of pipelines.
High temperature resistance and anti‑aging property for superior coating durability
It has a low thermal expansion coefficient, offering high‑temperature resistance and resistance to thermal cycling. The coating resists cracking, pulverization and peeling under long‑term service conditions, providing long‑term protection for pipe inner walls.
Applications
Widely used in systems including wear‑resistant ceramic coatings for pipe inner walls, anti‑corrosion paints for desulfurization and denitrification pipes, wear‑resistant layers for tailing transmission pipes, protection for chemical acid‑alkali pipes, heavy‑duty anti‑corrosion coatings for sewage pipes, and anti‑erosion coatings for fan ducts.
