Permabond 4C30 Instant Adhesive intermediate viscosity, high purity, medical device grade, cyanoacrylate adhesive

Product Name

Permabond 4C30 Instant Adhesive

Brief Description

Permabond 4C30 is an intermediate viscosity, high purity, medical device grade, ethyl cyanoacrylate adhesive. It is a one-component, fast-curing adhesive specifically formulated for bonding various materials in medical device assembly and high-speed production lines.

Popular Applications & Uses

- Bonding medical devices- Applications on medical device materials such as metal, rubber, and plastics- High-speed production lines- Gap filling for custom tube sets- Assembly of disposable medical devices- Bonding or coating interior joints and exterior surfaces of medical devices- Production of single-use items like catheters, respiratory and anesthesia masks, syringes, needles, and cannulas- Lifesaving equipment such as resuscitation tubes, respirators, and blood filters

Industries that Commonly Use It

- Medical Device/ Prosthetics

Special and Unique Features

- Medical device grade formula- High purity- Fast-setting/rapid-curing- Intermediate viscosity- Some gap fill ability- Ideal for automated dispensing- One-component adhesive (no mixing required)- Cures at room temperature- Withstands EtO sterilisation- Passes USP Class VI and Cytotoxicity requirements (ISO 10993 biocompatibility standards)

Known backups / known substitutes

- Loctite 4011 (medical grade ethyl cyanoacrylate)- ASI MG Series Medical Grade Cyanoacrylate Super Glue- Infinity Bond Medical Device Super Glue Cyanoacrylate- MXBON 22401 Medical Grade CA for Insensitive Surface- Cyberbond Apollo 2241-05- Other medical-grade ethyl cyanoacrylates from manufacturers like Aron Alpha/Toagosei

Comparison Note

- Permabond 4C30 is a medical-grade cyanoacrylate, distinguishing it from general-purpose "super glues" due to stringent manufacturing, quality control, and adherence to biocompatibility standards like USP Class VI and ISO 10993.- It offers precisely controlled viscosity and cure speeds tailored for medical device substrates, unlike consumer super glues with limited variability.- Its fast-setting nature and ability to bond a wide range of materials make it ideal for high-speed production lines in medical device manufacturing, often replacing less durable solvent adhesives or mechanical fasteners.
