About Cyanoacrylate Adhesives

封次still manufactures the original cyanoacrylate formulation Permabond 910 (previously Eastman 910). The name 910, comes from counting to 10 as the inventor determined that the product sets between 9 and 10 seconds.

由于原始的氰基丙烯酸酯配方,Permabond扩大了其氰基丙烯酸酯产品线的多功能性,包括大量配方,每个配方都具有克服特定设计和制造挑战的独特特性。包括更多的甲基氰基丙烯酸酯,还包括乙醇丙烯酸酯,烷基烷基氰基丙烯酸酯等。

封次cyanoacrylates are ideal for bonding materials such as metal, rubber, composite, plastic, silicone, and many more substrates. New formulations continue to eliminate design challenges encountered by engineers trying to bond difficult plastics such as polypropylene, polyethylene, PTFE, and other polyolefins. Permabond’s high-performance industrial cyanoacrylate adhesives that are available provide very fast set times, a range of viscosity choices as well as non-blooming / low odor formulations, and products with very high-temperature resistance.

什么是氰基丙烯酸酯?

简而言之,氰基丙烯酸酯是一种丙烯酸单体,可以治愈“塑料”。

How Do Cyanoacrylate Adhesives Work?

封次’s cyanoacrylate adhesives (also called instant adhesives or super glue) cure by reacting to very small amounts of moisture on the surface of the components being bonded. That’s it – no ovens, no mixing, no specialty curing equipment – they simply cure from the residual moisture naturally occurring on the surface of the components. Permabond recognizes that in applications such as wire tacking and tamper-proofing the adhesive is not compressed between two surfaces. For this type of application where the adhesive is exposed, activators are available. Simply spray the activator on the exposed cyanoacrylate to instantly cure it. Cyanoacrylate activators can also be used on very dry or acidic parts or to facilitate cure prior to wicking into porous substrates.

Key features

  • Gap fill ranges for cyanoacrylates are 0.015mm (0.006″) to 0.5mm (0.02″).
  • 温度电阻范围为-55至 +250°C(-55至 +482°F)。
  • 粘度范围从镍级到触变的无流凝胶

专业等级

  • 金属粘结
  • Plastic Bonding
  • Low Odor – Non-Blooming
  • 表面不敏感 - 对于酸性表面
  • High-Temperature Resistant
  • Toughened – for Improved Impact Resistance
  • NSF Non-Food Compound P1

无论你是使用cyanoacrylates成键,sealing, tamper-proofing, wire tacking, or simply as a manufacturing aid while you wait for another adhesive to set, Permabond’s research and development team continually push the limits of cyanoacrylate technology.

Highlights of a few products follow …

高温阻力

二次固化后,腐烂的产物919、920和922抗拒250°C(482°F)。Permabond 820具有最高的温度抗性,技术将承受200°C(390°F),而无需二级热固化。

No Drip Gel

Permabond具有许多非常高的粘度氰基丙烯酸酯,并提供了真正的触变凝胶粘合剂。该触变凝胶是针对需要粘合剂即使在垂直表面上保持在位的应用的专门配制的。凝胶也表面不敏感,因此它粘合了包括酸性底物在内的各种底物。

Non-Blooming and Low Odor

Blooming can be seen as a fine white residue that surrounds the bond area. Permabonds 940 series is non-blooming and virtually odor-free. Permabond’s chemists perfected the low odor technology so the adhesives are fast curing and provide high strength to a variety of surfaces.

Impact Resistance

By nature, cyanoacrylates are not incredibly impact resistant. Permabond’s toughened grades, Permabond 731, 735, and 737 provide the ultimate impact and peel resistance. They were initially designed for flexible substrates but the added flexibility and toughness of these products provide even greater shear strength on rigid materials like steel. Permabond 735 and 737 are opaque black and Permabond 731 is crystal clear.

NSF Non-Food Compound S4

封次2011Gel is listed on the NSF non-food compounds registry. Permabond 2011 is a non-sag, non-drip, thixotropic gel that forms strong bonds to metal, plastics, elastomers, ceramics, and wood. This product has excellent gap-fill capability, {(0.50mm) 0.020 in} and develops strength rapidly. Handling time can be achieved in less than 10 seconds. Once fully cured the bonds are high temperature resistant {(-55 to +120°C) -65 to +250°F} and have good resistance to non-polar solvents. In addition to Permabond 2011 now registered as NSF S4, Permabond has several products listed to NSF/ANSI 61 for potable water as well as epoxies that comply with the FDA Food Grade Codes CFR 175.105 and 175.300.
