Gel time, s：≤45
Show dry time, s：≤120
Tension strength, MPa：≥12.0
Classification:
Polyurea
Key words:
Polyurea
Product Overview
Polyurea is a high-molecular-weight explosion-proof coating formed by the rapid reaction of isocyanate and amino compounds. It is a block copolymer composed of hard and soft segments. Hydrogen bonds between the hard segments lead to microphase separation and self-assembly. After reaching a certain thickness, its mechanical properties are suitable for explosion-proof strength.
Application Scenario
Suitable for workshop wear-resistant heavy-duty floors, sports stands, metal protection, tank body anti-corrosion and other occasions; it has been widely used in construction, transportation, water conservancy, chemical, mechanical and electrical, environmental protection and other fields, especially in intercity and city Excellent performance in rail transit, high-speed rail bridge concrete surface waterproofing, etc.
