Five new Araldite structural adhesives launched

We are in the process of bringing into our range five new Araldite structural adhesives, which join the Araldite 2000 Plus line of products. Download the latest Selector Guide to get an introduction to the new adhesives and their capabilities. Maybe you have a bonding application which we can solve?

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.

New image for dispensing leaders

Congratulations to sales partner Fisnar Inc. Not only have they moved to new premises, but have undergone a bit of an image change. Here is their new logo - we like it.

Ultra-Red Adhesives for high contrast bond-line inspection and product verification

We are persuading our customers to “see red” literally. The Ultra-Red™ fluorescing technology built into many DYMAX adhesives offers assemblers concrete advantages in plastics fabrication.

Many plastics naturally fluoresce blue under UV light – this minimizes the inspection advantages of using blue-fluorescing adhesives in parts assembly. Ultra-Red™ fluorescing adhesives remain naturally clear until exposed to UV light, at which point they fluoresce bright red providing a vivid contrast that permits accurate bond-line inspection. The red fluorescence does not absorb the same light energy wavelengths as those used to cure the adhesive, resulting in faster and deeper cures when compared with the same adhesives containing blue fluorescence.

Ultra-Red™ fluorescing technology can also be used by manufacturers for product authentication. By virtue of its patented technology, the red-fluorescing compound is exclusive to DYMAX for use in radiation-cured adhesives and coatings. When measured, this technology produces a distinctly unique energy peak that cannot be reproduced by any other fluorescing compound. This offers manufacturers the ability to assemble or mark their products and be assured that, in the event of a future challenge as to the authenticity of the product’s origins, the products can be positively identified. Ultra-Red™ fluorescing technology is RoHS compliant.

Clear encapsulation ideal for LEDs

Opti-tec 4200 is an encapsulant/potting compound and adhesive. This optically clear polyurethane is ideal for use in electronics or electrical equipment which incorporates LEDs or other items where high transparency and aesthetics are important. Its clear, non-yellowing, hard setting properties will be appreciated in outdoor signage, illumination projects, e.g. pathways, swimming pools or fountains and in large public installations. It can be used for protecting photovoltaic and solar panel projects.

Opti-tec 4200 features excellent non-yellowing colour stability, due to the incorporation of both UV resistant base materials and the addition of UV stabilizers and antioxidants. It may be used for a range of applications from high value LED panels to decorative giftware (e.g. flower impregnation). It is also an excellent resin for the doming of badges, labels and decals.

Further important features include its hard set which enables it to resist impacts and mechanical loads better than silicones. It is also easy to mix, with very low viscosity, excellent penetration/air release, low shrinkage and low exothermic properties. Opti-tec 4200 is available in a convenient side-by-side double syringe cartridges, twin pack sachets and bulk packaging.
