  • ColorClear
  • Clear bond on metal, plastic and rubber
  • Very high strength on close-fitting parts
  • Moisture cure reaches handling strength fast
  • Low 100-120 cps viscosity flows into tight gaps
  • Electrically insulating for electronic assemblies

Purpose & user

Loctite 135429 Series 401 is a clear instant adhesive supplied in a 20 g bottle. It bonds metal, plastic and rubber with very high strength on close-fitting parts. The moisture-cure formula reaches handling strength quickly for general assembly and repair tasks.

Thermals noise power

As a single-component cyanoacrylate adhesive the product generates no heat, noise or electrical draw during application or cure. It hardens by reacting with ambient moisture on the substrate surfaces. No external energy source or dispensing equipment is required.

Deciding spec

Viscosity ranges from 100 to 120 cps and maximum gap fill is .005 in, so the adhesive suits tight joints but will not bridge larger gaps. Buyers needing to fill wider clearances or bond porous materials such as wood or fabric should select a different formulation.

  • Clear bond on metal, plastic and rubber

Questions about this item

How do I apply the adhesive from the 20 g bottle and what step is often missed?

Apply a thin layer to one surface, join the parts immediately, and hold them firmly until the moisture cure sets; the step often missed is using only enough adhesive to fill the 0.005 in gap.

What maintenance or replacement will the 20 g bottle of Series 401 need later?

The adhesive cures on exposure to moisture, so the bottle must be kept tightly sealed; replace it when the contents thicken beyond the 100 to 120 cps viscosity range or no longer bond plastics, metal, and rubber.

What limit appears first during sustained bonding with this instant adhesive?

The 0.005 in maximum gap fill is reached first; joints wider than this will not achieve the very high strength rated for close-fitting parts.
