JGN806 Crack sealing Adhesive

classification:

Structural strengthening

Product Overview
Epoxy Grouting Adhesive is a high performance construction material specifically designed to fill and repair cracks and voids in concrete, masonry and other substrates. Due to its excellent adhesion, strength and durability, Epoxy Grouting Adhesive is widely used in civil engineering, building rehabilitation, bridge maintenance and industrial equipment.

Product Features
Strong adhesion: excellent bonding properties with a wide range of substrates (e.g. concrete, stone, steel, etc.) to ensure structural soundness.

High strength: cured epoxy resin grouting adhesive has high compressive and tensile strength, suitable for withstanding larger loads, long-term use is not easy to fail.

Chemical resistance: good resistance to acids, alkalis, oils and a variety of chemical substances, suitable for use in harsh environments.

Low Shrinkage: Extremely low shrinkage during the curing process, which can effectively avoid cracks caused by shrinkage and maintain structural integrity.

Good fluidity: In the liquid state, the grouting adhesive has good fluidity and can penetrate into small cracks to ensure adequate filling and sealing.

Areas of application
Concrete Repair: Used to fill cracks and defects on concrete surfaces, restoring structural strength and safety.

Bridge Maintenance: Used for crack repair and reinforcement of bridges to improve the service life and safety of bridges.

Industrial equipment: Used for repairing and sealing industrial equipment to enhance the reliability and durability of the equipment.

Tunneling and underground engineering: effectively fill the cracks in underground structures to prevent water seepage and soil loss.

Instructions for use
Substrate treatment: Ensure the surface of the substrate to be grouted is clean and dry, remove dust, oil and loose particles.

Preparation and mixing: Prepare the epoxy resin and hardener according to the proportion in the product manual and mix well.

Injection: Use a syringe or grout injector to inject the mixed grouting adhesive evenly into the cracks to ensure that the adhesive is fully filled.

Curing: After the injection is completed, keep the environment dry and avoid external force and moisture intrusion, and wait for its curing.

Repair of high-strength concrete surface defects and pits; leveling construction of concrete adhesive surface in carbon fiber reinforcement or sticking steel reinforcement; anti-corrosion construction of bridges and other concrete surfaces (anti-carbonization, waterproof, anti-corrosion); concrete surface decoration protection; concrete surface crack closure.

Precautions
Safety Protection: Wear protective gloves, mask and goggles to avoid direct contact with skin and inhalation of harmful gases.

Environmental conditions: Construction should be carried out under suitable temperature and humidity, avoiding use under extreme weather conditions.

Storage conditions: Unused products should be stored in a cool and dry place, avoid direct sunlight and high temperature environment.

Conclusion
With its excellent performance and wide range of applications, epoxy resin grouting adhesive has become an indispensable material in modern building repair and maintenance. It can not only improve the safety and durability of the structure, but also extend the service life of the building. With the continuous progress of technology, the performance and application areas of epoxy resin grouting adhesive will be further expanded to provide more innovative solutions for the construction industry.
