White Papers

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... Continue reading →

Detlef Heindl explores the use of electrically conductive adhesives as an alternatvie for soldering, discussing the measurement of conductivity, climatic influences and curing options.

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... Continue reading →

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... Continue reading →

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... Continue reading →

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...

Since adhesives and sealants must function by surface attachment, the nature and condition of the substrate surface are critical to the success of any bonding or sealing operation. This white paper, written by Edward M. Petrie addresses the various issues related to silicone contamination including how it disrupts adhesion, detection methods, and cleaning processes. The author beleives the best policy... Continue reading →
