Electrolube Demonstrates Calibration of Two Part 2K Coatings

Reading time ( words)

In response to ever-increasing performance challenges, Electrolube, the global electro-chemicals manufacturer, has developed a new generation of two-part 2K conformal coatings to provide even greater protection. 2K coatings match the protection offered by an encapsulation resin with the easy application of a coating and have been rigorously tested in a variety of harsh tests, including thermal shock, powered salt-spray, condensation and mixed flowing gas (MFG) testing, with unprecedented results. The 2K has proven a popular product with the market and with a simple valve modification to existing dispensing equipment, and some software upgrades, the system is ready to go following calibration.

In a new ‘how-to’ video, Electrolube demonstrates how to set up and calibrate equipment for the 2K series following the installation of the valve. Once the 2K coating material is within the static mixer, the reaction agent will begin to respond and start curing the coating. It is imperative to purge regularly at each stage of calibration to ensure that any cured material in the machine is flushed through to achieve the desired effect from the coating process.  

Calibrating the machine will be assisted by your machine supplier. Electrolube has been working with machine manufacturers such as PVA, Mycronic and Nordson Asymtek to produce their valves, ensuring they are suitable for 2K materials. The main differences between the 2K coating applicators and single-component applicators are the twin progressive cavity pumps, leading to the static mixer.  There are some software alterations also where there are options for coating only, reaction agent only or mixed material. There is also the all-important purge button, which is important for avoiding blockages when material has been left too long in the static mixer, and a new tab that includes information regarding the mix ratio, flow rate and temperature. Unlike traditional coatings, the flow rate should always be controlled within the software, rather than adjusting the micrometre.

Ron Jakeman, Electrolube’s Managing Director comments, “Following the successful launch of our 2K series of Conformal Coatings, we have often been asked how they work and what the differences are between applying 2K coatings versus traditional solvent-based materials. To answer this, plus other very frequently asked 2K questions, we have created a series of videos to demonstrate production set up and the application of 2K material. This illustrates how easy it really is to transition to 2K materials.”

Four Silver Linings in the Stormy Clouds of Pandemic, Supply Chain, and Inflation

09/14/2022 | Dr. Ronald C. Lasky, Indium Corp.
It may be difficult to see any bright spots in the current and recent economic situation. We have all experienced the devastation of the pandemic, supply chain issues, and most recently, inflation. However, as a senior technologist for an international materials supplier (Indium Corporation) and a professor of engineering at an Ivy League research university (Dartmouth College), I offer these four silver linings for those of us in the electronics industry.

Thriving Through Greater EMS Collaboration

08/23/2022 | Chris Peters, USPAE
Events of the past two years have clearly demonstrated the value of strong trading relationships. When materials become constrained, as in the recent microchip shortage or any of the pandemic-driven supply chain snafus, the companies that have those materials have a choice to make. Which customers will be put at the front of the line, and which will be placed at the rear? Too often, company executives assume that since they are a large buyer, they automatically will be prioritized when supplies are constrained. Research has shown that this is not always the case, and that assumption can leave a company in a weakened position.
