The latest upgrades to low odor, low bloom Loctite® Instant Adhesives from Henkel Corporation maintain bond strength in high-humidity environments while delivering temperature resistance to 200°F. Virtually free of pungent odors, Loctite® 403, Loctite® 408, Loctite® 455 and Loctite® 460 low odor, low bloom instant adhesives minimize frosting near the bond line, maintain fast fixture speeds, and provide bond strengths of 2600 psi on dry or acidic surfaces. 

The four upgraded low odor, low bloom Loctite® Instant Adhesives are ideal for applications where the aesthetics of the end product are critical. Low odor, low bloom instant adhesives minimize the frosty, white film that sometimes develops near the bond line of traditional instant adhesives, and offer a reduced chemical smell for work in confined spaces or areas with low air flow. Loctite® low odor, low bloom products are available for gap filling, wicking into tiny spaces, bonding porous surfaces, and bonding close-fitting parts. All four products resist temperatures to 200ºF, cure on dry or acidic surfaces, and bond to a wide range of substrate materials. 

Each of the four upgraded low odor, low bloom Loctite® Instant Adhesives are formulated to cover a range of assembly requirements. Loctite® 403 is a medium-viscosity cyanoacrylate adhesive that fills gaps to 0.008 inches, while Loctite® 408 is a water-thin wicking grade adhesive designed to fill gaps as small as 0.002 inches. Loctite® 460 is a low-viscosity grade specifically formulated to work on close-fitting parts with gaps up to 0.004 inches. Ideal for porous surfaces, Loctite® 455 is a non-drip gel that fills gaps to 0.010 inches. All four grades provide shear strength to 2600 psi.
