Pulvawear™
- Chemical Family
- Epoxy & Epoxy Derivatives
Pulvawear™ is a wear-resistant coating designed specifically for use in coal pulverizing mills. When applied to classifier cones, mill walls, and other internal components, the composition of dense alumina spheres and micro ceramic powder in a ballistic grade aramid fiber reinforced epoxy matrix provides exceptional service life. Typical coal mill operating temperatures optimize the protective properties of Pulvawear™. Hudco Pulvawear™ has a service life in coal pulverizers that typically exceeds 5 years. Pulvawear™ comes in a complete kit with mixing and application tools.

- Safety Precautions
Protection Procedures If used in a confined or an enclosed area, use an air supplied mask or respirator with canister for organic vapors and provide mechanical exhaust ventilation. Use protective gloves, safety glasses, and protective clothing. Avoid contact with skin and clothing. Contaminated clothing should be laundered before wearing again. Contaminated shoes should be thoroughly cleaned before wearing again.
- Typical Applications
In addition to coal pulverizing mills, PulvaWear™ also provides excellent wear protection in a wide range of applications including chutes, screw conveyors, pneumatic conveying equipment and other equipment subject to fine particle abrasion.
- Application Instructions
Surface Preparation: Roughen surface by grinding or sandblasting (3-5 mil surface profile). Surface must be completely dry with a minimum surface temperature of 75° F. Mixing: Mix 4 parts of resin to 1 part of hardener by weight. Kits are supplied in the correct ratio. Ensure that the sides of the mixing container are scraped into the mixture. Mix several minutes, until consistent color is achieved. Application: Apply product to prepared surface and use supplied tools to achieve desired finish. Curing: At 75° F, product will gel in 60 min. Initial cure will occur in 6 Hours. In order for the product to reach its 300° F potential, it must be post cured for 4 hours at a temperature of 200° F or higher.
