Heavy Duty Anti-corrosion Pure Polyurea for the Petroleum and Chemical Industry EX-952
Heavy Duty Anti-corrosion Pure Polyurea for the Petroleum and Chemical Industry EX-952
Description
EX-902 heavy-duty anti-corrosion polyurea material for the petroleum and petrochemical industry is a two-component elastic material composed of a semi prepolymer with A component as the end NCO group, and an R component consisting of end amino polyether, amine chain extender, and additives. EX-902 can be used alone or in combination with other materials as a surface anti-corrosion coating, lining, wear-resistant layer, and medium resistant layer for metals, concrete, or other substrates. EX-902 can form hard coatings of different thicknesses and can be applied to various occasions and handle suitable substrates. EX-902 is insensitive to moisture and humidity, and can be used in harsh environmental conditions.
Key Characteristics

Not sensitive to moisture and temperature, with good thermal stability.
Has excellent resistance to media such as acid, alkali, and salt.
Operating temperature (-45~150 ° C), with a wide range of operating temperatures.
100% solid content, no VOC, no pollution, environmentally friendly.
Has good adhesion to metal substrates and concrete substrates, and does not peel off after long-term use.
Excellent physical performance.
Good weather resistance, no powdering, and no color loss.
The coating is seamless and has a smooth appearance.
Application
EX-902 heavy-duty anti-corrosion polyurea material in the petrochemical industry has an extremely fast reaction speed, with a single spray thickness of tens of millimeters, and can be widely used in steel chemical equipment and concrete tanks in industries such as petrochemicals, petroleum, and chemical engineering; Including desalination water tanks, storage tank bodies, tank cofferdams, oil and gas pipelines, etc
