LEDs

In the last few years there has been a surge in the growth and proliferation of Light Emitting Diodes (LED’s) and other Solid State Lighting throughout virtually every sector of the business community. Wherever you turn, LED’s are replacing the common filament bulb. Almost overnight, we find LED’s have taken the place of products that have remained unchanged for years - flashlights, auto headlamps, outdoor billboards and advertisements, street lights, and traffic signage, just to name a few. Other Solid State Lighting devices, OLED’s (Organic Light Emitting Diodes) and PLED’s (Polymer Light Emitting Diodes), have worked their way into television screens, computer monitors, mobile phones, PDAs, watches, and advertising signage as well. However, the emergence of LED’s and other Solid State Lighting as an innovative, reliable and energy-saving alternative has not been without its own set of challenges. Kisco Conformal Coating has risen to these challenges and provided a solution.

LED’s are typically more complex than a standard bulb. They consist of a semiconductor diode that emits light when a current is applied - the color of which is affected by the condition and composition of the semi conducting material used in the diode itself. The units are small and energy efficient, hence their growing use in almost every sector:

• Advertising (billboards, scoreboards, displays)
• Military Defense applications
• Aviation, Aerospace
• Electronics
• Automotive
• Medical

 LED’s are assembled in circuits, panels and/ surface mount devices (SMD), depending upon the application. This presents a variety of complications, as most are susceptible to the elements, particularly heat, ultraviolet rays and moisture. Other types of coatings have been used to offer a measure of protection, but they typically add weight, don’t penetrate all crevices, are not pinhole free, or they distort light emanating from the LED’s.

Kisco Conformal Coatings has the solution. With its large arsenal of parylene dimers, it has already distinguished itself as the premier coating partner to some of the largest LED display manufacturers in the world. Also, our parylenes are the purest (99.9%) in the industry, and our inventory of variants means we can likely match exactly what you need for your products and displays.

Kisco Parylene is proud to announce diX-SF, a parylene dimer that is ideally suited to the needs of customers seeking to coat LED panels or displays destined for use outdoors (exposed to the harmful effects of heat, moisture and UV light). Kisco Conformal Coating has 11 parylenes to serve you (not the typical 2-3 as elsewhere in the coating industry), but our diX-SF is an ideal solution for the most difficult challenges.

• UV stability: dix-SF provides the ultimate in UV protection. This particular dimer is the parylene specifically formulated to resist the discoloration and cracking resulting from direct UV exposure. Offering maximum protection from the elements (heat, moisture and UV), diX-SF is the perfect choice for outdoor LED panels and displays. Unlike other conformal coatings, diX-SF offers a total solution.
• High thermal resistance: Kisco Conformal Coating’s diX-SF parylene coating is an extreme heat-stable variant which functions effectively at temperatures of over 300°C continuous (and up to 450°C for intermittent periods).
• Moisture resistance: All of Kisco Conformal Coating parylene coatings are characterized as excellent moisture barrier. They ensure against failures due not only to moisture, but also for m a protective barrier protecting your displays against damage caused by virtually all other fluids and chemicals.
• Uniform and conformal protective layer: As diX parylene is deposited as a vapor, it can effectively penetrate the smallest and deepest of crevices. It doesn’t form a pool or a meniscus and follows precisely the contours of any substrate.
• Lowest dielectric constant and dissipation factor: Kisco Conformal Coating offers parylene products which all possess very low dielectric constant, meaning a high dielectric withstand, and dissipation factor.

Kisco is truly a LED expert as many LED materials are manufactured and distributed by Kisco Group companies. For example, EpiFine encapsulation material has the highest market share in the world, and our customers include all major LED manufacturers.
