    The polyurethane paint film is bright, plump, hard and wear-resistant, resistant to oil, acid, chemicals and industrial waste gas, good electrical properties, and can be miscible with a variety of resins.
    The formula can be adjusted in a wide range to meet different needs

    .
    Widely used in wood, automobile, aircraft, machinery, electrical appliances, instrumentation, plastic, leather, paper, fabric, petrochemical and other aspects

    .

    Polyurethane coating films with high mechanical abrasion resistance and toughness coatings online coatingol.
    com

    .
    At the same time, polyurethane coatings have both protective and decorative properties, and can be used for the coating of high-grade wood, pianos, large passenger aircraft,

    etc.
    Polyurethane, like epoxy, can be formulated as an excellent adhesive

    .
    Therefore, the coating film has excellent adhesion to various surfaces (metal, wood, rubber, concrete, some plastics, etc.
    )

    .


    Polyurethane coatings are non-toxic and environmentally friendly


    Polyurethane waterproof coating, a new type of polymer multifunctional material
    .
    The waterproof coating has good water resistance, impermeability, heat insulation, corrosion resistance, extensibility, adhesive strength, black color, long service life, low price, cold construction, convenient use and less odor

    .
    Polyurethane waterproof coating is a new type of waterproof material that is non-toxic, tasteless and has good decorative effect

    .



    Now the polyurethane waterproof coatings are upgraded, all of which are environmentally friendly coatings
    .
    Polyurethane waterproof layer has good waterproof and impermeability performance, heat insulation and anti-corrosion effect, high bonding strength, good extensibility, strong corrosion resistance, long service life, and cold construction

    .
    The polyurethane coating has non-toxic, tasteless and good decorative effect, it is a new generation of waterproof material varieties

    .


    Polyurethane coatings for fans


    Fan equipment is widely used for ventilation, dust removal and cooling in factories, mines, cooling towers, vehicles and buildings, ventilation and drafting in boilers and industrial furnaces, cooling and air conditioning in air conditioning equipment and household appliances.
    ventilation

    .
    The dust, moisture, acid, alkali, etc.
    that the fan equipment comes into contact with during the use process will cause corrosion to the surface.
    In order to better protect the fan, most of the fans are protected by spraying

    .


    In order to meet the requirements of environmental protection, water-based paint can also be used for fan painting.
    The water-based acrylic polyurethane topcoat has the same performance characteristics as solvent-based paint, and is water-based and environmentally friendly, with little environmental pollution, and is suitable for projects with high environmental protection requirements

    .


    Polyurethane coatings for bridges


    Polyurethane coatings still play a leading role
    .
    In recent years, the practice of large-scale heavy-duty anti-corrosion coating projects in China has shown that the two-component acrylic polyurethane topcoat has been successfully applied in the fields of bridges, fans, hydropower, thermal power, petrochemical plants, large oil depots, marine engineering, and civil machinery due to its excellent cost performance.
    , has accumulated a wealth of construction experience

    .


    Aliphatic polyurethane coating is a high performance long lasting heavy duty anticorrosion coating which is widely used in most severe corrosive environments
    .
    As far as the salt spray resistance index of polyurethane topcoat and its supporting coatings is concerned, the relevant national industry standards generally stipulate that it is 1 000 h (such as HG/T 3656-1999 "Steel Structure Bridge Paint", TB/T 2773-1997 " Therefore, the salt spray resistance of this matching coating system is excellent compared with similar domestic products, and it is widely used in steel structure projects at home and abroad, and has been widely praised

    .


    Polyurethane coating for cold storage


    It is necessary to choose special spray paint for cold storage, which has a large temperature range of anti-aging strength, high free foam density, and polyurethane rigid foam is not brittle under -50 ℃.
    affect the thermal insulation effect

    .


    Polyurethane is an inert material, it does not react with acid and alkali, and it is not a food source for insects and rodents, so it can keep the material properties and thermal insulation performance constant; Wind resistance: compressive strength> 300Kpa, tensile strength> 400Kpa , It has strong wind resistance, and its foam can be drilled into the wall gap to increase its shear resistance
