ZL-C Carbon Fiber Impregnation Adhesive
ZL-C carbon fiber impregnation adhesive (structural adhesive for bonding fiber-reinforced composite materials) is a two-component modified epoxy resin-based adhesive, serving as the primary bonding agent for reinforcing methods involving fiber-reinforced composites (such as carbon fiber fabric, carbon fiber boards, glass fiber fabric, aramid fiber fabric, etc.). It is typically used in conjunction with ZL-X concrete repair adhesive (structural reinforcement leveling adhesive), applied at different stages of the reinforcement construction process. This product meets the technical requirements for Class A adhesives outlined in GB50728 "Technical Specification for Safety Assessment of Engineering Structural Reinforcement Materials" and JTG/T J22 "Code for Design of Highway Bridge Reinforcement," and has successfully passed the national standard 90-day thermal aging performance test.

Product Advantages
1. High strength, strong bonding capability;
2. Anti-aging, with excellent resistance to acids, alkalis, and water;
3. Offers a longer application period but cures quickly;
4. Strong impact resistance, making it suitable for dynamic load reinforcement in structures like bridges;
5. Easy to use and non-toxic; it doesn’t drip or sag during facade application, and exhibits minimal shrinkage during the curing process.
