Bio-based hot melt adhesive supports structural bonding applications
HENKEL LOCTITE HHD 3544F bio-based polyurethane reactive (PUR) hot melt adhesive is suitable for consumer electronics assembly. Approximately two-thirds of the product’s content is sourced from renewable, plant-based feedstocks. A one-part, moisture-cure material, product delivers a sustainable production alternative that provides many market-leading advantages. 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).
