Title: Performance Advantages of Using Silicones as Conformal Coatings vs other Materials
Various conformal coating materials are used to provide protection and improve performance and reliability of PCBs. Despite the higher gas permeability of silicone relative to other polymers, formulation design approaches and improvements in adhesion can allow silicone to mitigate gas permeability concerns and deliver corrosion resistance performance that meets emerging expectations for conformal coatings. The paper includes performance comparison data of silicone to other conformal coating materials such as acrylic, polyurethane and epoxy based on the following tests: Gas Permeability Sulphur Resistance Test Gas Corrosion Resistance Test Salt Spray Resistance.
Title: Electrically Conductive Adhesives - A Smart Solution as an Alternative to Soldering
Electrically conductive adhesives play a vital part in the electro- and electronics industries. These adhesives are the perfect choice for attaching and connecting electrical or electronic components. In a growing number of applications, they are used as a more effective alternative to conventional soldering. Crucial for a successful application is not only the right choice of the adhesive, but also the right curing parameters.
Title: Fundamental Principles of UV Reactive Manufacturing Processes
This white paper 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. Hoenle explore the fundamental principles of UV reactive manufacturing and the processes available.
Title: UV Curing Adhesives Compatible with Common Sterilisation Processes for Medical Products
Dr Detlef Heindl from our supplier partner Panacol, provides expertise on how UV curing adhesive technology can be a cost-effective solution to connect components for single use medical products, as well as being very compatible with common sterilisation processes such as autoclaving, gamma and ETO. All products available within this range are USP VI and/or ISO 10993 certified.
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 compiled 21 Reasons you should use adhesives to bond plastics over other bonding methods.

Title: How To Choose The Right Instant Adhesive For Your Manufacturing Process
This helpful article reviews the factors which need to be taken into consideration when choosing the correct cyanoacrylate (instant) adhesive for your process. Explaining the correct applications to use low vs. high viscosity products, along with substrate identification and the effect of environmental elements.
Title: Is LED the UV Curing 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. Honle questions if LED is the future of UV technology and have produced an objective comparison between UV-LED & conventional UV technologies.Title: Addressing Silicone Contamination Issues
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. One of the most important parameters is surface cleanliness or the absence of contaminants that can impair adhesion.
Title: 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. Advances have been made in bonding polyolefin based materials through improved surface preparation processes and the introduction of new adhesives that are capable of bonding to the polyolefin substrate without any surface pretreatment. Adhesion promoters for polyolefins are also available that can be applied to the part prior to bonding similar to a primer.
Title: Adhesive Testing
This article 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. The importance of standardized test methods is emphasized as well as the process of designing an adequate test program. Fundamental material property tests, tests to determine the working characteristics of the adhesive, and performance tests are identified but not expounded in detail.
Title: Innovative Medical Disposable Device Assembly: LED Curing Adhesive Technology
Light curing adhesives are mainly used in the assembly of disposable medical products with high throughput. The speed of dispensing and curing of such materials enables the manufacturer to reduce production costs, associated with remarkable lower consumption of energy, decreasing the carbon footprint as well. 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.
