Permabond 4C20 Medical Grade Cyanoacrylate Adhesive, Fast-Setting, 400-600 cP Viscosity, 0.008 in Gap Fill (Glue Only, 1oz)

Permabond 4C20 is a high-performance, fast-setting cyanoacrylate adhesive designed for demanding industrial applications. This colorless adhesive features intermediate viscosity (400-600 mPa.s) and achieves handling strength in just 10 seconds on steel, rubber, and phenolic materials. With its ability to fill gaps up to 0.008 inches and form strong bonds on various materials including plastics, rubber, and metals, it's ideal for high-speed production lines. The adhesive delivers impressive shear strength of 2900-3200 psi on steel and maintains effectiveness across a wide temperature range. Its intermediate viscosity makes it perfect for automated dispensing systems, while its medical device grade formulation meets stringent quality standards. For optimal performance, surfaces should be clean and grease-free, and an activator may be recommended for difficult-to-bond materials. This professional-grade adhesive requires 24 hours for full strength development and features a Shore D hardness of 85.
