Henkel introduces dual cure adhesive 26 May 2022

Henkel has developed LOCTITE® STYCAST® OS 5101, a dual cure adhesive for optimal, precise optical lens and component alignment during the in-line assembly process. 

The new adhesive provides robust dimensionally stable adhesion for optical lens and component bonding and builds on the company’s growing portfolio of data centre optics products and has been designed to provide excellent alignment accuracy for maximum light transmission in high-speed optical transport network solutions.  

“As Cloud scale and hyperscale data centres continue to evolve to meet demanding data management bandwidth expectations, data centre interconnections are becoming increasingly more powerful and efficient,” says Wayne Eng, global head of data and telecom market strategy at Henkel. “Transceivers are the key building blocks for high-speed data transmission and their assembly integrity is more critical than ever before to protect device investment, ensure long-term reliability, and optimise function.” 

Tim Munks, senior principal analyst at Omdia added: “Transceiver development has dramatically accelerated to keep pace with the exponential data processing demands, as is evidenced by the quick move from 100 GbE to 400 GbE to now 800 GbE modules. Over the next four years, we expect the unit volume CAGR for 400 GbE to be greater than 200% and more than 300% for 800 GbE. Optical communication efficiency is the key to meeting the expectations for Cloud, video, gaming, work and learn from home applications – and it is only getting more intense. Transceiver reliability, signal integrity and lower loss optics are critical.”

In order for optical signals to transmit with minimal loss, meticulous alignment of lenses and optical components is required. After a first stage UV partial cure, LOCTITE STYCAST OS 5101 allows precise positioning of optical lenses within the transceiver optical sub-assembly and, once final thermal curing takes place, the material maintains its dimensional stability to ensure accurate lens position while in operation. In addition to high reliability as confirmed by high temperature or high humidity, thermal shock and high temperature storage testing, internal results also indicate that material properties of LOCTITE STYCAST OS 5101 are capable of delivering low moisture absorption, strong adhesion to substrates and high UPH capability with energy savings.
