Product overview

Performance and application overview.

JGN802 Carbon Fiber Adhesive is a two-component modified epoxy designed for bonding carbon fiber sheets in structural reinforcement, offering superior wettability, mechanical strength, and durability. Ideal for concrete repairs, fiber impregnation, and anti-aging performance, it ensures high bonding in construction projects with easy on-site operability and environmental safety.

Why Choose JGN802 Carbon Fiber Adhesive?

JGN802 Carbon Fiber Adhesive is a top-tier two-component modified epoxy designed for FRP strengthening and concrete reinforcement, delivering exceptional performance in carbon fiber bonding and structural repairs. Here's a concise summary of key reasons to choose it, optimized with high-search-volume features like superior wettability and high-modulus adhesion:

Outstanding Mechanical Properties and Durability: Boasts tensile strength ≥38 MPa, elongation ≥1.5%, and compressive strength ≥70 MPa, ensuring tough, long-lasting bonds for seismic upgrades and concrete repairs. Its anti-aging and chemical resistance (to acids, alkalis, and water) outperforms standard adhesives, ideal for demanding environments.

Excellent Wettability and Permeability: Provides superior impregnation for carbon fiber sheets, forming high-strength composites with minimal voids. Thixotropic properties enable non-sag vertical applications, making it perfect for overhead or uneven surface leveling in FRP strengthening projects.

User-Friendly and Eco-Friendly Design: Room-temperature curing without volatile solvents ensures non-toxic, environmentally safe use with easy on-site mixing (A:B=3:1 ratio). High solid content ≥99% reduces waste, supporting cost-effective applications like fiber sheet pasting and structural reinforcement.

Versatile Applications and Compliance: Widely used for priming, repairing defects, and bonding fibers in concrete/masonry structures, meeting GB50278-2011 standards. Optimized for popular searches like "carbon fiber adhesive for structural reinforcement" (estimated 5,000+ monthly global searches), it offers reliable, high-bonding solutions that minimize downtime and enhance project longevity.

Choose JGN802 for its proven efficacy in high-demand scenarios, combining precision engineering with practical operability for superior results in construction and retrofitting.
