CET-2002P

Polyurethane Adhesive for Piezo Sensors

YD-2002P is a solvent-free, environmentally friendly cold-curing adhesive used for encapsulating or surface bonding of piezo traffic sensors.

Specifications:

Package Size: 4 kg/set

Usage Instructions:

Mix components A and B thoroughly using an electric drill for 1-2 minutes.

Experimental Data:

YD-2002P is used for encapsulation and may occasionally exhibit sedimentation, especially if stored for a long period or at low temperatures. However, sedimentation can be easily dispersed using an electric drill with a wide blade.

• Color: Black

Performance Tests:

• Compression Test Result: 26 MPa
• Tensile Test Result: 20.8 MPa
• Fracture Elongation Test Result: 7.8%
• Adhesion Strength Test (C45 Steel-Concrete Direct Pull Bond Strength): 3.3 MPa (Concrete cohesive failure, adhesive remained intact)

Hardness Test (Shore D Hardness Meter):

• After 3 days at 20°C-25°C: 61D
• After 7 days at 20°C-25°C: 75D

Important Notes:

• Do not repack into smaller samples on-site; the adhesive should be used all at once.
• Laboratory samples can be prepared following precise ratio instructions for testing.

Installation Guide:

1. Sensor Installation Groove Dimensions:

• Recommended groove width: Sensor width +10mm
• Recommended groove depth: Sensor height +15mm

2. Surface Preparation:

• Use compressed air to remove dust and debris from the concrete surface.
• Ensure the concrete surface is dry before application.

3. Adhesive Preparation:

1. Mix components A and B with an electric tool for 1-2 minutes. (Mixing time should not exceed 3 minutes.)
2. Immediately pour the mixed adhesive into the prepared groove. (Do not leave mixed material in the container for more than 5 minutes.)
3. Flow Time: At room temperature, the material remains workable for 8-10 minutes.
