  • PRODUCT DESCRlPTlON

    PubraTM Polyurea Abrasion-Resistant Coating for Mining is a third-generation polyurea elastomer composed of prepolymer, polyether, amine chain extender, nano-fillers, etc., formed through on-site spray application. This technology combines new materials, new equipment, and new processes organically, representing a revolutionary leap in traditional construction techniques.

    PROPERTIES

    ·Solvent-free, green, environmentally friendly, and pollution-free.

    ·Fast curing speed; equipment can be put into use shortly after spraying.

    ·Seamless monolithic structure via spray application, eliminating stress points with excellent waterproof and anti-corrosion properties.

    ·Insensitive to moisture and temperature, ensuring stable construction and reduced foaming risk.

    ·Wear resistance 10 times that of carbon steel, far superior to traditional wear-resistant materials and rubber products.

    ·Excellent physical properties: high resilience, impact resistance, and tear strength.

    ·Outstanding chemical resistance, resistant to seawater, acids, alkalis, and salts.

    ·Excellent weather resistance, no chalking, cracking, or peeling after long-term outdoor use.

    APPLICATION

    PubraTM mine wear-resistant material is specially designed for rubber conveyor belts and linings of mining equipment, widely applicable to coal mine chutes, cement mortar processing equipment, vibrating screens, flotation cells, ore washing drums, spiral separators, grinding equipment, hydraulic classification, and various other wear-resistant applications.

    SAFETY PRECAUTIONS

    · It is strictly forbidden to have any open flames in the batching and construction site, and good ventilation should be maintained Constructionpersonnel must wear protective gear to avoid skin contact.

    · If the paint splashes on the skin, it should be cleaned immediately with an appropriate cleaning agent or soapy water.

    · If it splashes into the eyes, rinse them repeatedly with clean water, keep the eyes open, and seek medical treatment immediately.

    DISCLAIMER

    · The above information is compiled based on the actual tests and usage experience of our company's technical personnel and can be used as a construction guide. However, due to differences in the painting environment and supporting schemes, it is recommended that users conduct preliminary tests and trials according to their actual needs and purposes before confirming the use. Our company only guarantees the quality and stability of the product itself. When our company's technical personnel are not on the painting site, our company is only responsible for the quality of the coating product itself.

    · The protective effect of any coating highly depends on the painting construction. Construction factors such as surface treatment and film thickness will directly affect the service life of the coating. When using this product, users should meet the agreed construction conditions.
