Unpacking the Rising Popularity of LED Curable Conformal Coatings

 
The transition to LED curable conformal coatings is beginning to build momentum, beginning as a slow evolution and developing into a revolution of sorts. The driving forces behind this include: 
 
• Improved processing equipment designs and availability 
• Aging or outdated application equipment replacements 
• Increasing range of LED curables commercially available or in development 
• Rising labor, equipment, and energy costs  
 
Benefits of LED Curable Conformal Coatings 
There are countless advantages to choosing LED curable coatings, including:
 
• Processed on the same commercial spray equipment as traditional conformal coatings
• less need for expensive curing enclosures
• consistent and repeatable cure 
• lower energy requirements
• little or no hazardous wavelengths generated 
• less heat generation for sensitive components 
• longer bulb life and lower maintenance costs 
 
Common Applications for LED Curable Conformal Coatings
 
LED curable coatings are suitable for nearly all conventional conformal coatings applications. Their lower energy and maintenance requirements combined with short cycle times make them especially valuable in certain areas including 
 
• Automotive PCBs due to their high volumes and energy requirements  
• White goods such as refrigerators, washers, and dryers 
• HVAC control boards 
• Electronic vehicle applications including power and safety controls and autonomous driving devices 
 
HumiSeal LED Curable Products 
 
Chase Corporation and HumiSeal, a leader in the field of conformal coatings and electronics protection, has developed a substantial range of LED curable coatings and gels to meet this growing demand. These coatings and gels exhibit all the advantages related to LED curable materials as well as a number specifically designed for the demands of PCB protection. 
 
Products include: 
• UV20 Gel
Flexible, thixotropic gel designed for staking and vibration protection for larger components such as capacitors and batteries 
 
• UV40 LED
LED curable version of the industry standard UV40 coating specified by many automotive and white goods OEMs for over a decade 
 
• UV500-2
Newest, LED curable version of Humiseal UV500, a more flexible and wider operating window version of standard UV40 
 
• UV550
LED curable designed with maximum flexibility for the most demanding, high cycle count thermal and mechanical shock environments.
