Epoxy Resin for Carbon Fiber to Repair Building Cracks

Product Description

Introduction:
This product is high performance epoxy adhesive, which can be used for the effective penetration bonding to many substrate materials such as concrete,
steel material, ceramic, stone, wood component, and many fiber fabrics, e.g. carbon fiber, glass fiber, basalt fiber, and aramid fiber.

Properties:
Low viscosity: Good impregnating properties, can well infiltrate the carbon fiber fabrics, good thixotropic properties makes it easy to apply.
Compatibility: Good compatibility with carbon fibers.
Anti-corrosion: Excellent durable performance, corrosion resistance, humidity and moisture resistance, and chemical corrosion resistance.
High property: After curing, it has good physical properties, good toughness and elastic properties.

1. Surface Preparing: Remove the coating of concrete surface with grinder. Polishing the Surface. If there is angular, grinder it into round.

2. Setting out: Get the concrete surface clean and keep it dry, then setting out.

3. Apply Primer: Apply primer adhesive onto the surface of the concrete.

4. Apply Putty/Leveling: Apply putty for repairing and leveling if needed.

5. Fabric Cutting: Cut carbon fiber fabric into sizes as designed.

6. Preparing the impregnation adhesive: Weight and mixing adhesive according to ratio. Stirring the adhesive until the color is even. Avoid air bubble in this process.

7.Applying Impregnation Adhesive: Apply impregnation adhesive when primer adhesive is touch dry. (If primer is not required, impregnated adhesive can be applied directly.)

8. Apply carbon fiber fabric: Apply carbon fiber fabric onto the concrete surface as designed. Leveling the surface from one end to another.

9. Check Gap or Bubble: Apply impregnation carbon fiber adhesive again. Make sure the adhesive impregnate fully into the fabric. The surface flat and no air bubble. Repeat above process from cutting carbon fiber if applying two or more layers.

Packing                      
The A and B components of this product are packed in separate metal containers. Group A is 20kg/container and Group B is 10kg/container.

Shelf Life

Transportation and Storage

This product should be kept sealed and stored in a dry and clean storage space of ambient temperature between -5 oC and 40 oC. In order to prevent damage, do not store outdoor under direct sunlight or under direct rain.

A & B components should be kept separately. Storage period is 12 months at room temperature (25 oC); if it is stored for more than 12 months, it should be tested. If the physical and mechanical properties after 12 months meet the standard requirements, then it could be used;

These products are not inflammable, explosive, toxic, or dangerous cargoes. They could be transported with general transportation cargo. The epoxy containers should not be damaged, exposed to direct sunlight or rain, and should not be tilted or stored upside-down during transportation.

Points for Attention
Mix proper amount of adhesive at one time, use up within the applicable period, do not use the adhesive if it is beyond the applicable period;

If components A and B of the adhesive are not used up, they should be covered and sealed. They should not be exposed to air for a long time;

The construction workers should take all necessary safety measures (such as wearing masks, gloves, goggles, etc.), and maintain fire prevention measures, as well as keeping the site clean;

If the adhesive accidentally got in touch the skin and cloths, acetone can be used to wipe it at once, followed by a great deal of clear water;

If accidentally swallowed or splashed into the eyes, please seek immediate medical service.
