HumiSeal announces its NEW reduced bubble conformal coating to SMT Nuremberg 2022 


HumiSeal, a leading conformal coatings manufacturer, has announced it will use the SMTconnect event in Nuremberg, Germany (10th – 12th May 2022) to launch a brand-new product designed to specifically address the reduction of bubbles being experienced by some users of conformal coatings. Visitors to the HumiSeal stand in Hall 4-211 will discover more about the new product called 1B73/730EU which features a totally new solvent blend which reduces bubbles during application. 

HumiSeal 1B73/730EU is a single component, fast drying, acrylic conformal coating intended for use on printed circuit assemblies. HumiSeal® 1B73/730EU is specially formulated with a new solvent blend to reduce bubbles during application. HumiSeal® 1B73/730EU is formulated with the same base acrylic resin as HumiSeal® 1B73, and after complete cure, the properties of HumiSeal® 1B73 and the 1B73/730EU Pre-blends are comparable.  


HumiSeal® 1B73/730EU is also available at a range of viscosities, suitable for a variety of application methods without further dilution and has the following advantages:  

– Demonstrates excellent flexibility  

– Protection against moisture / salt environments and general contaminants.  

– Fluoresces under UV for ease of inspection and is easily repaired  

– Easy removal using HumiSeal® Strippers.  

– Improved application properties with reduced bubbles when applied with selective coating equipment  

– Meets requirements IPC-CC-830  

– Meets requirements of IEC 60664-3  

– Meets requirements of UL746E V0, UL File Number E105698  

– Compliant to REACH and RoHS Directive EU 2015/863  

– Compliant to China Standard GB30981-2020  


EMEIA Manager for HumiSeal, Katherine Blake commented on the announcement by saying: 

“The issue of bubbles forming during the application of conformal coatings is well documented and can be dependent on a wide range of parameters but are most commonly linked to spray and film coating where variables such as distance between nozzle and substrate and the additional pressure introduced to the fan width or material atomisation have all had an impact on the potential for bubbling to occur. The introduction of this new product is designed to reduce this phenomenon by using an entirely new blend of solvents whilst still maintaining all the advantages and characteristics our customers have come to expect from our materials.”
