Cemedine Super-X 8008: A Revolutionary One-Part Elastic Bonding Solution

In the fields of industrial manufacturing, electronic assembly, and daily repairs, high-efficiency, reliable, and adaptable adhesives are crucial for solving complex connection problems. Cemedine's Super-X series adhesive, particularly its flagship model Super-X No.8008 (RoHS), is precisely such a revolutionary product. It integrates three ideal properties: "pressure-sensitive adhesion," "elastic adhesion," and "solventless adhesion," providing an outstanding solution for multi-material bonding and demanding environmental applications.

The Super-X series is an outstanding representative of its innovative technological strength.

Super-X No.8008 is an epoch-making one-part quick-curing adhesive. It revolutionizes the operation methods and performance limitations of traditional adhesives. Its core value lies in perfectly achieving three ideal properties of adhesives:

1.Pressure-sensitive adhesion:

This is the most prominent feature of Super-X. After application, during a specific time window in the curing process (about 10 minutes), the adhesive layer exhibits pressure-sensitive properties. This means that pressing the two adherends together during this time results in instantaneous bonding, similar to rubber contact adhesives, eliminating the need for temporary fixation. This greatly simplifies the operation process and improves assembly efficiency.

2.Elastic adhesion:

The cured Super-X 8008 forms an elastic rubber-like hard film. This elasticity grants it excellent "conformability":

• Stress Absorption: Effectively absorbs and disperses internal stresses caused by vibration, impact, or differences in thermal expansion coefficients between different materials (e.g., bonding metal to plastic), significantly reducing the risk of bond failure due to stress concentration. Traditional rigid adhesives (like epoxy) are prone to cracking in such applications.
• Wide Temperature Resistance Range: The cured film maintains good elasticity and bond strength over an extremely wide range, from very low temperatures (-60°C) to high temperatures (120°C), adapting to demanding temperature cycling environments. The chart below demonstrates its excellent bond retention after repeated heating and cooling.

3.Solventless adhesion:

As a one-part solventless product, Super-X 8008 requires no mixing during use. It cures quickly at normal temperature by absorbing moisture from the air. This makes it not only easy-to-use but, more importantly, safe and clean. It eliminates the hazards associated with organic solvents, such as flammability and toxic volatile organic compounds (VOCs), making it more environmentally friendly.

1. Extensive Material Compatibility: Its extraordinary feature is its ability to bond a wide variety of materials, breaking through the material pairing limitations of traditional adhesives. The detailed bond strength table in the TDS shows that Super-X 8008 exhibits good to excellent bonding performance on metals (steel, aluminum, stainless steel, copper), plastics (PC, Bakelite/phenolic resin, ABS, plasticized PVC, PS, Acrylic/PMMA, 6-Nylon, FRP, PE foam, PP*, PEEK, PES, PSU, PET, PPS, PPO, PAR, polyester, etc.), rubbers (natural rubber, NBR, silicone rubber, SBR, EPDM, CR, CSM, etc.), slate, plywood, etc. (*Note: PP requires a special primer PP-5; PE foam requires UV treatment). This truly achieves "one adhesive for multiple uses," reducing inventory and selection hassles.
2. Excellent Durability and Reliability:
   • Chemical Resistance: After immersion in various chemicals (water, dilute acids, dilute alkalis, saltwater, machine oil) for 7 days, its tensile shear strength on stainless steel remains relatively high (see the chemicals table in the TDS for data). Although resistance to ketones (MEK) and alkane solvents (n-Hexane) is poor, short-term contact (e.g., during cleaning) is acceptable.
   • Electrical Properties: Volume resistivity ~1.1x10¹² Ω·cm, dielectric constant (@100Hz) ~6.15, providing certain insulation properties suitable for some electrical applications.
   • Quick Initial Curing: Tack-free time is approximately 11 minutes, reaching the pressure-sensitive range within about 10 minutes. After 7 days of curing, typical tensile shear adhesive strength can reach 3.7 N/mm² (e.g., on steel plates), and T-type peeling adhesive strength reaches 2.5 N/mm. Post-cure hardness (Shore A) is ~48, glass transition temperature (Tg) is as low as -63°C, breaking extension is as high as 220%, and linear expansion coefficient is ~2.1x10⁻⁴ /°C. These data fully demonstrate its advantages as an elastic adhesive.
   • Environmentally Friendly and Safe: Compliant with RoHS directive, formaldehyde grade reaches JAIA F** (highest grade by Japan Adhesive Industry Association), free of halogens, antimony oxide, phosphorus-based flame retardants, solvents, and very low VOC.

• Applications requiring initial bond strength: Utilizing its pressure-sensitive characteristics for rapid positioning and instant bonding, eliminating the need for clamps.
• Bonding of dissimilar materials (especially those with large differences in thermal expansion coefficients): Such as composite bonding of metal to plastic, ceramic, rubber, wood, etc. Its elasticity effectively compensates for differences in thermal expansion and contraction.
• Durable bonding requiring resistance to repeated heating, cooling, or vibration: Such as components near engine compartments, heated equipment, and interior parts of vehicles.
• Electrical contact failure countermeasure product: Its elasticity and insulation properties help secure electronic components, absorb vibration, prevent fretting wear, and improve the long-term reliability of electrical connections. Although the SX720 series is a more specialized electronic adhesive, 8008 also has application potential in less demanding situations.

Cemedine Super-X No.8008 is not just an adhesive; it represents a significant innovation in bonding technology. It perfectly integrates convenient operability (pressure-sensitive fast positioning), excellent adaptability (broad material bonding), outstanding durability (elasticity, weather resistance, temperature resistance), and environmental safety (solventless). Whether facing the challenge of complex multi-material bonding or ensuring the long-term reliability of connections in demanding environments, Super-X 8008 demonstrates robust capabilities and broad application prospects. It is not only a testament to Cemedine's technological strength but also a reliable partner for engineers and manufacturers in solving bonding challenges.
