LOCTITE® HHD 3544F Contains 60% Bio-Based Content, Provides Sustainable Alternative for Structural Bonding Applications

Henkel Develops Industry’s First Bio-Based PUR Hot Melt Adhesive for Consumer Electronics Assembly

Irvine, CA – Leveraging its broad innovation portfolio and in keeping with the company’s sustainability priorities, Henkel today announced the development and commercial availability of LOCTITE® HHD 3544F, the industry’s first bio-based polyurethane reactive (PUR) hot melt designed for consumer electronics assembly.  This is the company’s inaugural consumer electronics-specific, bio-based PUR hot melt adhesive; approximately two-thirds of its content is sourced from renewable, plant-based feedstocks. 

“LOCTITE HHD 3544F is an important advancement for the electronics industry,” explains David Peard, Henkel Market Segment Manager and Sustainability Ambassador for Consumer Electronics. “Replacing conventional fossil fuel-based raw materials with renewable substitutes is a challenging endeavor.  Nearly two years in development, LOCTITE HHD 3544F is a notable structural adhesive innovation and the first product in an expanding Henkel portfolio of bio and renewable material solutions for the consumer electronics sector.”

A one-part, moisture-cure material, LOCTITE HHD 3544F delivers a sustainable consumer electronics assembly alternative that provides many of the advantages associated with the market-leading family of Henkel PUR hot melts.  The bio-based formulation is compatible with a variety of substrates including plastics, metals and glass; aligns with high-volume production objectives, enabling deposition of narrow bond lines via jetting or needle dispensing; and, integrates fluorescence for in-line automatic optical inspection (AOI). LOCTITE HHD 3544F can be used for a wide range of consumer electronics structural bonding applications in mobile phones, laptops, tablets, wearables, and accessories.  

Acknowledging Henkel’s global leadership in sustainability and business responsibility, Peard heralds the commercialization of LOCTITE HHD 3544F as a significant milestone in the company’s consumer electronics strategy and notes its important role in helping customers achieve their own sustainability targets.   “Reducing our environmental impact and dependence on virgin fossil-based raw materials have been and will continue to be priorities for Henkel,” he says in summary.  “Industry-first LOCTITE HHD 3544F delivers solid performance built on a foundation of renewable resources – a win-win!”
