About CYH 500 Single Component Hydrophobic PU

Upon contact with water, CYH-500 reacts to closed cell rubber-like foam while expanding its volume up to 27 times. The cured material is of a constant volume. Since water is not a component of the foam structure, the cured material is essentially not affected by water or dryness. The reacted material does not shrink or swell. Depending on the pressure of injection, CYH-500 reacts to a very dense material or foam.

Advantages:

Negative side application possible
Deep penetration into very small cracks
Foam increases in volume to fill cavities and voids
Excellent bond to surfaces
Good adhesive strength, tolerant of movement
Inert after curing, constant volume, no shrinkage
Does not create new cracks

Effective Sealing for Concrete Structures

CYH 500 Single Component Hydrophobic PU is specially developed to effectively seal water leaks and repair cracks in concrete structures. Its expansive nature allows it to penetrate even fine fissures, ensuring comprehensive protection and strengthening of buildings. The product is ideal for facilities requiring reliable long-term solutions against water ingress and chemical exposure.

Rapid Curing and Strong Bonding

With an initial set time of only 2-4 hours and complete curing achieved within 24 hours, CYH 500 enables efficient project turnaround. Its strong adhesion to concrete, exceeding a bonding strength of 1.5 MPa after curing, ensures a durable and robust repair. The resin forms a firm, water-insoluble seal, enhancing the integrity of the treated structure.

FAQ's of CYH 500 Single Component Hydrophobic PU:

Q: How is CYH 500 Single Component Hydrophobic PU applied for crack repair?

A: CYH 500 is applied using an injection pump, which delivers the liquid polyurethane directly into cracks or gaps in concrete structures. Its low viscosity allows for deep penetration, and the material then expands to seal the area thoroughly.

Q: What benefits does CYH 500 offer in water leak sealing?

A: The resin's hydrophobic properties and significant expansion rate ensure that even active water leaks are efficiently blocked. Once cured, the product remains insoluble in water and maintains excellent chemical resistance, offering long-term protection against water ingress.

Q: When does CYH 500 reach full strength after application?

A: After injection, CYH 500 undergoes an initial set in 2 to 4 hours, depending on conditions. Full curing and maximum bonding strength are achieved after 24 hours, providing a durable repair solution.

Q: Where can CYH 500 be used effectively?

A: CYH 500 is suitable for use in industrial, residential, and commercial concrete structures, including basements, tunnels, foundations, and water retaining structures. Its versatility makes it an ideal choice for both new and renovation projects.

Q: What is the shelf life and optimal storage conditions for CYH 500?

A: CYH 500 has a shelf life of 12 months if stored between 5C and 35C in its original sealed container. Proper storage away from direct sunlight and moisture preserves its quality and performance.

Q: Is CYH 500 safe to use in environments inhabited by people?

A: Yes, CYH 500 is non-toxic after curing, making it safe for use in environments where people live or work. It is important to follow safety guidelines during the injection process, and ensure adequate ventilation.

Q: What is the main advantage of using CYH 500 for structural crack repairs?

A: CYH 500 provides rapid and reliable sealing that strengthens the structure due to its high expansion rate, strong adhesion to concrete, and resistance to water and chemicals. This makes it an effective solution for long-term durability and protection.
