Carbon Fiber Adhesive

Unlike small-scale repackaging workshops, we maintain full, independent control over the entire value chain—from raw epoxy resin procurement and formula R&D to automated filling and third-party authoritative testing. All structural reinforcement adhesives are manufactured in strict accordance with the *GB 50367 Code for Design of Strengthening Concrete Structure*.

We operate an in-house standardized chemical laboratory equipped with universal testing machines, aging test chambers, and acid/alkali immersion testing equipment. Every batch of carbon fiber adhesive undergoes rigorous sampling tests for bond strength, compressive strength, temperature resistance, and impermeability before leaving the factory. We provide comprehensive test reports, certificates of conformity, and factory quality warranties, offering a one-stop solution for project tender documentation.

For years, we have been a reliable supplier to domestic structural reinforcement companies, design institutes, and general infrastructure contractors. Our products have been used in diverse projects—including school renovations, municipal bridges, high-rise residential buildings, and industrial facility reinforcements—and their performance has been validated by thousands of real-world applications. We ensure consistent, reliable quality, effectively eliminating common industry issues such as diluted adhesives, inflated strength ratings, and tendencies to crack or delaminate.

JUN TENG A-grade carbon fiber impregnated adhesive performance parameter table

This Carbon Fiber Adhesive is a two-component modified epoxy impregnating adhesive specially designed to match our factory's 200g/300g unidirectional carbon cloth and bidirectional woven carbon cloth. The adhesive has excellent thixotropy and does not flow or hang during facade and ceiling construction. There will be no waste of adhesive flow or pollution of the base surface caused by wall sagging; Highly permeable, it can penetrate into the fine pores of concrete, firmly locking in carbon fiber bundles and forming an integrated load-bearing layer between carbon cloth and walls, thereby enhancing the building's load-bearing capacity from the source.

Five core product advantages

1. National standard A-level compliance, worry free engineering bidding fully complies with concrete reinforcement specifications, third-party testing reports are complete, school, government, and municipal reinforcement projects can be directly tendered and used, qualifications are complete and not subject to review, avoiding the risk of poor quality non-standard adhesive acceptance.

2.In 2018, the factory independently developed a formula that maximizes the compatibility of carbon cloth. It is specially formulated with colloidal viscosity for its full range of carbon fiber cloth, which will not cause problems such as too thin or too thick colloids that cannot penetrate carbon fibers. After pasting, there will be no hollowing or bubbles, and the reinforcement effect will be doubled.

3. Water resistance, moisture resistance and aging resistance, waterproof and anti-seepage after indoor and outdoor general curing, long-term use of basements, pools and open bridges without degumming, and the strength degradation is extremely low under the repeated action of ultraviolet, rain and temperature difference, and the service life of building reinforcement can reach more than 30 years.

4. The construction is simple and easy for beginners to operate with a standard 2:1 ratio. After mixing evenly, the coating can be applied, and with the help of rollers and scrapers, carbon cloth impregnation can be completed. After curing, there is no pungent odor. It can be safely used for home decoration, renovation of old houses, and small-scale construction sites.

5. In stock from the source factory, supporting customized services with 5kg and 20kg standard barrel ready stock, and delivering large quantities of vehicles directly; We can customize low-temperature and high contact type special ratio colloids according to the customer's construction environment, and can print customer specific packaging labels for large quantities.

Carbon Fiber Adhesive is only suitable for concrete and cement mortar base surfaces. When used with JUN TENG base adhesive and repair adhesive, it can further enhance the adhesion of the base surface. For loose and sandy walls, the base surface should be repaired first and then coated with carbon cloth adhesive for stronger reinforcement stability.

Standard Construction Simplified Process

1. Base treatment: Polish and remove floating dust, hollows, and oil stains on the wall, clean cracks, and repair them flat

2. Apply primer: evenly roll apply matching epoxy primer to seal loose base surface and enhance bonding strength

3. Mix carbon cloth adhesive: Stir for 3 minutes in a ratio of A to B of 2:1 until the color is uniform

4. First layer of adhesive coating: Apply a layer of impregnating adhesive evenly on the concrete base surface to ensure complete coverage

5. Paste carbon fiber cloth: Lay the carbon cloth flat, use a roller to repeatedly roll and press it to eliminate bubbles, and ensure that all carbon fibers are fully saturated

6. Surface coating: Apply a layer of adhesive on the surface of the carbon cloth, completely covering it, and allow it to cure naturally for 24 hours to reach initial strength

Frequently Asked Questions for Customers

1.What is the difference between this adhesive and low-priced carbon cloth adhesive on the market?

Low priced products on the market often recycle inferior epoxy resin, which results in inadequate bonding strength and delamination after six months of exposure to sunlight and humid environments; JUN TENG has its own chemical production line and produces new raw materials. Each batch is sent for inspection, and the reinforcement completion can pass the acceptance of the housing and construction department. Long term engineering quality assurance is guaranteed.

2.Can construction still be carried out in low temperature environments in winter?

Regular models can be constructed normally at temperatures above 5℃, and below 5℃, customer service can be contacted to customize low-temperature dedicated carbon fiber adhesive. It does not crystallize at low temperatures and has stable curing speed

3.How many square meters of carbon fiber cloth can be matched with one bucket of glue?

The 20kg standard set can impregnate about 80-100 square meters of 200g unidirectional carbon cloth, with uniform construction thickness and no waste. The actual usage varies slightly with the roughness of the base surface.
