- Description
- Technical specification
LOCTITE® 460 is a low odor, low-bloom instant adhesive. This low-viscosity adhesive is ideal for applications where odor and/or blooming are a concern. LOCTITE 460 provides for rapid bonding of metals, elastomers and plastics, including difficult-to-bond plastics (PP, PE, PTFE) when used in conjunction with a primer such as LOCTITE SF 770.

How to use
It is recommended to use the correct LOCTITE® cleaner for the surface to be bonded (such as LOCTITE® SF 7063 or SF 7070) to degrease and clean surfaces prior to applying the adhesive.
To improve adhesion on difficult to bond plastic surfaces, apply LOCTITE® SF 770 to the bond area by brushing or dipping. Avoid applying excess primer. Allow the primer to dry.
If cure speed is too slow, use appropriate activator LOCTITE® SF 7455 or LOCTITE® SF 7452. Apply activator to one bond surface by spray, brush or dipping (not primed surfaces). Allow the activator to dry.
Apply adhesive to one side or part.Recommended dispensing equipment: for precise dispensing of small amounts of adhesive, use dispensing needles.
Assemble parts immediately. The parts should be accurately located as the short fixture time leaves little opportunity for adjustment. Bond should be held or clamped until the adhesive has fixtured. Hint: if necessary, excess product can be cured by activator LOCTITE® SF 7455 or LOCTITE® SF 7452. Spray or drop activator onto excess product.
For precise dispensing of small amounts of adhesive, the use of dispensing needles is recommended.
FAQ
Low odor/low bloom instant adhesives are significantly higher in molecular weight than traditional instant adhesives. Therefore, they are less prone to become airborne when left open to air and consequently produce little to no blooming, or “frosting” effect on assemblies. They also tend to have lower odor during use.
This is called blooming. This often occurs when there is an excessive amount of product being applied. To avoid blooming, use proper ventilation, less product, lower humidity, use a primer/accelerator, or a low bloom product.
This is a result of stress cracking. Leaving uncured liquid CA remaining on some plastic substrate (such as polycarbonate, acrylic, and polysulfone) in a stressed condition may cause the formation of cracks in the plastic. Some remedies for avoiding/minimizing stress cracking are closing the bond joint quickly, use reinforced grades of plastic, anneal parts, or speed the cure of the CA with accelerator (or light for light curing CA products only)
Yes, CA’s should be stored in the refrigerator prior to opening, but DO NOT refrigerate them once they have already been opened. After opening, CA's should be used within 30 days for best performance.
