Latest selector guide for medical device adhesives

Recently, we updated our website with an enhanced version of the comprehensive DYMAX Selector Guide on MD® Adhesives for Medical Device Assembly. This valuable tool contains a number of charts intended to help R&D engineers and product designers choose the appropriate adhesive for their application. All DYMAX MD® Adhesives are biocompatibility tested in accordance with ISO 10993 and/or USP Class VI.

Pages are devoted to specific adhesives for the assembly of catheters and guidewires, injection needles and syringes and respiratory devices. Recently developed products incorporating new technologies such as See-Cure and Ultra-Red fluorescing have been integrated into the guide together with charts, photos and technical information which are presented to simplify and shorten the adhesive selection process and to explain the new technologies.

For the designer with a new or unique disposable-device application, the multi-purpose bonding charts quickly show the range of products available, their technical data, and the various substrates to which they adhere. Most products shown bond well to a number of plastic substrates (including those which are more specialist to the medical field), as well as to dissimilar substrates such as metal, glass and ceramic. While most formulations cure instantly upon exposure to UV/visible light, the line of MEDI-CURE® 222 Series Cyanoacrylates is offered for bonding opaque substrates and for applications where aggressive adhesion to rubber is needed.

On the last page of the guide is a selection of curing and related equipment built to optimize both performance and cost savings. Our Application Engineers can help you match the resin to the appropriate equipment as an aid to simplifying assembly process development and validation.

An instant classic

We are pleased to announce a significant new range of professional grade cyanoacrylate “instant” adhesives - superior quality, high purity single part adhesives which have numerous applications in all aspects of high technology, high performance assembly. Curing at room temperature in seconds, they provide excellent bond strength on a wide range of similar and dissimilar substrates including rubber, plastics, metal, wood, leather, ceramics, ferrites, stone, cork, glass, composites and paper. The range includes surface-insensitive, fast cure and low odour, low blooming formulations. Cyanoacrylate adhesives (CA’s) are known generically as “superglues” or “instant adhesives” and are extensively used in all manner of industrial applications, but often little understood and may be of extremely variable quality.

Our adhere cyanoacrylate single component systems are fast and easy to use, requiring no mixing or heating, and parts being bonded do not need clamping. They are solvent free. They achieve high tensile and shear strengths. Their high quality formulation and manufacture ensures excellent manufacturing repeatability and high stability – facilitating long shelf life for highly efficient production line use. The range includes a rubber toughened “flexible formulation”, an activator for even faster cures, and a primer which facilitates bonding of difficult to bond plastics such as polypropylene, polyethylene or silicone rubber – even PTFE.

While cyanoacrylates are ubiquitous adhesives we believe they are often taken for granted. It is our aim to raise-the-game of instant adhesives in manufacturing processes. To this end we are also strongly focused on dispensing technologies, whether through 20 or 50 gram integral pin cap HDPE bottles or 500 gram bottles for pressure pot and automated application. We score by offering a complementary complete range of compatible automatic, semi-automatic and manual dispensing systems in-house.
