LOCTITE 408(pc)

Loctite 408 Instant Adhesive is a low-odor, low-bloom cyanoacrylate (CA) adhesive built for fast, reliable bonding where appearance and vapor control matter. Its very low viscosity allows Loctite 408 instant adhesive to flow easily into tight-fitting joints and bond by capillary action, making it ideal for close-tolerance parts, porous materials, and cosmetic assemblies where the white "frosting" or blooming common to standard super glues is unacceptable. Loctite 408 bonds metals, elastomers, and plastics rapidly, and with the addition of a compatible primer it can also bond difficult-to-bond plastics such as polypropylene (PP), polyethylene (PE), and PTFE. Tapemart, a genuine Loctite distributor, keeps Loctite 408 instant adhesive in stock for electronics assemblers, manufacturers, and repair professionals who need a clean, dependable instant bond.

Key Features and Benefits

•      Low-odor formula reduces airborne vapor, suitable for use in enclosed cells, benches, and small workspaces

•      Low-bloom chemistry minimizes the white frosting effect around the bond line, ideal for visible or cosmetic assemblies

•      Very low viscosity for excellent wicking into tight-fitting parts and porous substrates such as wood, leather, and fabric

•      Fast fixture time of approximately 5 to 10 seconds, accelerating assembly throughput

•      Bonds metals, rubbers, plastics, and porous or absorbent materials effectively

•      Compatible with Loctite SF 770 primer for bonding difficult plastics like PP, PE, and PTFE

•      Ultra-clear, transparent cured bondline for a neat finished appearance

Typical Applications

Loctite 408 instant adhesive is widely used in electronics assembly, small component manufacturing, and precision bonding tasks where odor control and a clean cosmetic finish are priorities. Typical uses include bonding tight-fitting plastic and metal components, securing small mechanical parts, repairing or assembling rubber and elastomeric parts, and bonding porous materials such as wood, paper, leather, and textiles. Because of its very low viscosity and wicking behavior, Loctite 408 instant adhesive performs especially well in narrow-gap or capillary-fit joints where thicker adhesives would struggle to penetrate fully.

How to Use Loctite 408 Instant Adhesive

Clean and degrease both bonding surfaces using a suitable Loctite cleaner, such as Loctite SF 7070, before application. Apply Loctite 408 to only one of the two bonding surfaces — never both — and avoid spreading it with tissue, brushes, or other absorbent tools. Position and assemble the parts within a few seconds, as the fast fixture time leaves little room for adjustment once contact is made. Hold or clamp the assembly until the adhesive fixtures, and allow 24 to 72 hours at room temperature for the bond to reach full strength before subjecting it to service loads, depending on the bond gap and substrate. For bonding difficult plastics such as PP, PE, or PTFE, pre-treat the surface with Loctite SF 770 primer. Store Loctite 408 in a cool location, ideally refrigerated between 2°C and 8°C before opening, and use within 30 days of opening for best performance. Always follow the official Loctite 408 technical data sheet and safety data sheet, since cyanoacrylates bond skin instantly and require careful handling.
