CYH-303
High Flexible PU Foam (Double Components Type)
Injection Grouting Chemical
CYH-303 is self-reacting of double components(Resin & Hardener) type
hydrophilic polyurethane which has polyether polyol properties.
CYH-303 applies to the leakage area for the waterstops where has vibration also
because it has elastic property foaming ratio with water is very lower than normal PU foam (Hydrophobic type).
CYH-303 density is high and hardened foam is same like a rubber. Therefore, it is useful for the expansion joints and water
leakage caused by deformation. Waterproof effects last semi-permanently.
It provides strong physical strength after contact with water.
So these properties brings excellent bonding strength to give
the waterproof ability and reinforcement. It is high elastic PU material.

CYH-303
High Flexible PU Foam (Double Components Type)
Injection Grouting Chemical
Feature
- The hardened foam cannot be fractured by compression test
because it has elastic characteristic material.
- It has strong adhesive. So it has strength and high elasticity on
both wet and dry cracks because it is self-reactive type,
dual components PU resin. Also, it has an effective on
reinforcement and waterstops.
- CYH-303 provides good waterproof effect because of it's low
viscosity and it's enable to penetrate into fine crack.
Also it is easy to inject the fine leakage areas.
- You have enough time(approximately 60~100min.) to inject
PU resin after you mix the double(Main&Hardener)
components, So you are able to inject the PU foam by using
single component injection pump(CY-1000, CY-800M1).
Usage
- Tunnel, Expansion joint. Basement. Moving structure.
- Utility boxes, Sewers, Dams, Subway(Metro) Concrete joints.
Defective concrete.
- Underground concrete structures, Basement parking area.
- For repair of dry & wet cracks and reinforcement for
every concrete structure.
Important Notes
- Minimum ambient and substrate temperature is 5℃
- Store in cool and dry places.
- Good storage stability for unopened containers at 15~30℃
