"What Is The Compatibility Of Adhesive (Using For Wrapping Frp) WithThis Old Structure"

The compatibility is good betweeb old structure and carbon fiber adhesive,

HM-180 primer is used to the concrete surface treatment.

Primers are often used to improve adhesion, especially in challenging or non-ideal surface conditions.  It can enhance the compatibility and bonding between the adhesive and the old structure. 

Here are some key points to assess compatibility:

Surface Condition: Evaluate the condition of the old structure's surface. Adhesives typically require a clean, dry, and well-prepared surface for proper bonding. Remove any loose paint, rust, or other contaminants that could affect adhesion.

Material Compatibility: Identify the material of the old structure. Adhesives have varying degrees of compatibility with different materials. Common structural materials include concrete, steel, wood, or masonry. Consult adhesive manufacturer guidelines or technical data sheets to determine if the adhesive is suitable for bonding to the specific material.

Adhesive Selection: Choose an adhesive specifically designed for bonding FRP to the old structure. There are adhesives formulated for this purpose, ensuring good adhesion and long-term performance. Seek recommendations from adhesive manufacturers or industry experts to find a suitable adhesive for your application.

Environmental Factors: Consider the environmental conditions the adhesive will be exposed to, such as temperature variations, moisture, UV exposure, or chemical exposure. Ensure the adhesive is resistant to these factors and suitable for the specific project requirements.

Structural Load and Design: Evaluate the structural load requirements and design considerations. The adhesive should have sufficient strength to bear the anticipated loads and meet the necessary design standards.
