Henkel’s new active alignment adhesive can be cured in a single step with three seconds of UV LED light exposure.
Loctite Ablestik NCA 01UV reaches its full performance and final bond strength with seconds of UV LED irradiation during the fixing step. Hence, time- and energy-intensive post-curing by oven is no longer required. By avoiding the high capital expenditure of heat cure ovens and the associated operating and maintenance costs as well as manufacturing space demands, this simpler process also makes a compelling commercial case.
Loctite Ablestik NCA 01UV 1-step cure adhesive meets all requirements for high resolution cameras for automotive applications, while matching its dual-cure predecessors. With low and consistent dimensional change of 0.4% during cure, this new adhesive is a reliable candidate for high resolution camera modules for automotive as no change in focus from an excessive shrinkage is to be expected. In order to meet the requirements for automotive grade for camera module adhesives, Loctite Ablestik NCA 01UV shows high reliability and dimensional stability, as well as no outgassing from volatile compounds, ensuring a high image quality and no fogging on the optical system. In line with Henkel’s commitment to developing safer and more sustainable solutions, it is free of CMT, SVHC, or any toxic substances and fully EU REACH-compliant.
Rodrigo Aguilar, ADAS business development manager at Henkel, said: “By enabling active alignment of ADAS sensors to within 100-nanometer accuracy, we are delivering the precision and high sensor reliability needed for vital safety functions.”
