Is LED the UV Technology of the Future?

For many years UV technology has been a reliable method for the curing of photo-reactive chemicals. In response to increasing production speeds and new applications UV lamp technology has also developed.

Hoenle questions if LED is the future of UV technology and have produced an objective comparison between UV-LED & conventional UV technologies.

Topics Covered:

  • Comparison of Technologies (UV and UV LEDs)
  • Fields of Applications
  • UV LEDs for Adhesive Curing
  • UV LED Curing in Printing
  • UV LED Measurement


Innovative LED Adhesive Technology for Disposable Medical Device Assembly

Light curing adhesives are frequently used in the assembly of disposable medical products with high throughput; the speed of dispensing and cure enables the manufacturer to reduce production costs.

Panacol’s medical adhesive portfolio allows a variety of different design and substrate options: needle to plastic and glass hubs and syringes, connectors, housings, filters, catheters, endoscopes, covers, blood filters, face masks and surgical instruments.


Fundamental Principles of UV Reactive Manufacturing Processes

In this white paper, Hoenle explores the Fundamental Principles of UV Reactive Manufacturing Processes; covering: the UV-Spectrum, Chemical Curing, Inertization, UV Irradiation, the advantages of UV curing and typical applications.

While the UV Systems technology and the appropriate chemistry have been developing continuously, the principle of irradiation curing has widely remained unchanged. High-energy UV irradiation causes chemical curing of UV reactive coatings within seconds.


Choosing the Right Instant Adhesive for your Manufacturing Process

The key to selecting the correct cyanoacrylate (instant) adhesive for your application is having a clear definition of your objectives. An adhesive cannot be selected based only on its bond strength, it is always best to look at as many factors as possible.

Techsil has collated a checklist of these factors to be conisdered when choosing an instant adhesive.

  • Materials to be Bonded
  • Mating of Bonded Surface
  • Speed of Cure
  • Asethetic Requirements
  • Assembly Environment
  • End-use Environment
  • Bond Stress
  • Joint Design


Bonding Plastics? Twenty One Reasons you should use Adhesives

According to the "Engineer's Guide To Plastics," published by Materials Engineering, adhesives are the most versatile assembly method for joining plastics. They are listed as being capable of joining 36 types of plastics compared to 28 types for mechanical fasteners, the next most versatile method. Methods such as heat staking and ultrasonic welding are limited by comparison, being suitable for 15 and 18 plastics, respectively.

Techsil has been exploring the advantages of adhesives over these other bonding methods for plastics and has compiled a list of 21 reasons to consider.

Topics Covered:

  • Advantages of Adhesives over Mechanical Fasteners
  • Advantages of Adhesives over Ultrasonic Welding
  • Advantages of Adhesives over Solvent Welding
  • Advantages of Adhesives over Solvent Cements


Adhesive Testing - A Necessary Cost?

Testing is an extremely critical function in the adhesive and sealant industry for several reasons. One cannot reliably predict the characteristics of the joint based solely on parameters of the adhesive, substrate, and joint design. Therefore, testing is necessary to confirm expectations.

This white paper, written by Edward M. Petrie reviews the importance of testing in the adhesive and sealant industry and why it is a necessary cost that must be dealt with by both the adhesive formulator and end-user. It discusses the importance of standardised test method as well as looking at the process of designing an adequate test program.

Topics Covered:

  • Necessity of Adhesive Testing
  • Importance of Standardised Testing
  • Fundamental Material Property Tests
  • Standadised Test Method to Determine Performance
  • Designing a Test Program


Adhesive Bonding of Polyolefin

Polyolefin polymers are used extensively in producing plastics and elastomers due to their excellent chemical and physical properties as well as their low price and easy processing. However, they are also one of the most difficult materials to bond with adhesives because of the wax-like nature of their surface.

This white paper, written by Edward M. Petrie reviews reasons why polyolefin substrates are so difficult to bond and discussed the various methods that can be used to make the task easier and more reliable.

Topics Covered:

  • Polyolefins and their Surface Characteristics
  • Polyolefins Surface Preparation Processes
  • Primers and Adhesion Promoters
  • Adhesives for Direct Bonding of Polyolefins
