What is polyurethane coating?
Polyurethane coating is a ceramic wear-protection product made from alumina or silicon-carbide ceramic combined with rubber, polyurethane or epoxy, used to protect equipment from abrasive and impact wear. A ceramic wear face is bonded to rubber, polyurethane or epoxy, marrying hardness with impact absorption. In mining, cement, steel, power-plant ash handling, chemical processing and lithium-battery material plants, they extend equipment life and cut maintenance.
What is polyurethane coating used for?
They protect process equipment from wear in mining, cement, steel, power-plant ash handling, chemical processing and lithium-battery material plants.
What material and properties make polyurethane coating effective?
A ceramic wear face is bonded to rubber, polyurethane or epoxy, marrying hardness with impact absorption. These properties let polyurethane coating outlast steel and rubber in abrasive service.
Why choose polyurethane coating over steel or rubber alternatives?
Polyurethane coating beat plain metal, rubber or polymer on abrasive duties: steel erodes in months and can contaminate product, while rubber gouges under lump impact. Polyurethane coating hold dimension, cut downtime and typically last 5–10× longer in mining, cement, steel, power-plant ash handling, chemical processing and lithium-battery material plants.
How do I select and specify polyurethane coating?
Tell FIRSTAR your equipment, material and wear mode; we specify grade, size and backing to match.
What maintenance do polyurethane coating need?
Little maintenance is needed beyond periodic inspection; because they wear slowly, planned replacement during shutdowns is usually enough. FIRSTAR can advise an inspection schedule.
