Spray polyurea waterproof coating performance and technology

2014.10.17   16:03

In recent years, spray polyurea waterproof coating got rapid development, widely used in construction, energy, transportation, water conservancy, chemical industry, electrical and mechanical, environmental protection and other fields, show In the strong vitality.

  Spray polyurea waterproof coating physical and chemical properties

  Excellent resistance to water penetration, and the overall seamless, compact structure, strong, strong bonding force, the real "skin type" waterproof. Can be used to meet the water polyurea waterproof, Can also be used to back the surface waterproof.

  Spray polyurea waterproof coating can be under 45 ℃ ~ 120 ℃ - use for a long time, heat resistant up to 160 ℃ (160 ℃ can withstand short time thermal shock).

  Good weather resistance, aging resistance. Aromatic polyurea under ultraviolet light erosion is yellowing phenomenon, but no pulverization and cracking, can use for a long time, resistance to freezing and thawing, Hot and cold shock and alternating shock of frost and snow storms.


Excellent physical properties. Polyurea tensile strength, tear strength, impact strength, bond strength, elongation, abrasion resistance, resistance to Pierce, rolling resistance, gave , prevent slippery wait for a characteristic, and has excellent resistance to cracking of concrete, the cracking of concrete protective and loss of strength concrete reinforcement of structure.

  Good antiseptic function. Polyurea corrosion resistant to most medium acid, alkali, salt, water, such as long-term immersion of chlorine ion.

  usability


Polyurea high reactivity, fast curing, vertical plane, top surface and arbitrary curved surface can spray is not flowing continuously.

  Spray polyurea waterproof coating without catalyst, 5 ~ 20 seconds gel, the intensity of 10 minutes to walk, can continuous spraying, a construction thickness is unrestricted, weeks of construction Short period and high efficiency. Node detail construction convenient, do not need special fiber reinforced layer.

  Spray polyurea waterproof coating to metal, nonmetal substrate has strong adhesion, such as steel, aluminum, reinforced concrete, wood, glass fiber reinforced plastic, polyurethane foam, etc . Polyurea elastomer on the compressive strength of concrete or 5 mpa (more than bond strength between concrete).

  Spray polyurea waterproof coating less sensitivity to temperature, humidity, when construction is less influenced by environmental temperature, humidity, with special primers in damp base construction.


Spray polyurea waterproof coating using complete sets of equipment for spraying, high production efficiency. With Graco - H - 35 pro Gusmer company equipment, maximum coating thickness in each shift 1 mm coating 2000 square meters. The coating surface is smooth and continuous without seam. By adjusting the parameters of the process, also can get "pits" surface, can also be surface sanding, increase Add concrete base with asphalt surface bonding force.

  Spray polyurea waterproof coating can join all kinds of pigment, according to the packing made into different colors and function of the coating, excellent decorative surface.
