Reliable bonding on difficult plastics

Practical benefits

Adhesion on polyolefin surfaces: You prepare low-energy plastics such as polyethylene and polypropylene for secure bonding with instant adhesives.
Loctite SF 770 primer: This liquid surface treatment significantly improves adhesive performance on substrates that are otherwise difficult to bond.
Easy control under UV: The fluorescent formulation allows you to verify uniform surface coverage quickly and accurately under ultraviolet light.

In a nutshell

The right choise for

Difficult-to-bond plastics such as polyethylene, polypropylene, and ptfe often resist standard instant adhesives. With Loctite sf 770 polyolefin primer, you prepare low-energy plastic surfaces for strong, reliable adhesion with cyanoacrylate adhesives. This liquid surface treatment is easy to apply directly to the plastic component, significantly improving adhesive performance. Thanks to its fluorescent properties under uv light, you can quickly verify complete and uniform coverage across the workpiece. This ensures fast, precise, and dependable bonding results during maintenance, prototyping, or industrial assembly.

Product description:

LOCTITE SF 770

Characteristics:

LOCTITE SF 770 is a primer used to make polyolefins and other surfaces with low surface energy, suitable for bonding with LOCTITE instant adhesives
The curing power of LOCTITE instant adhesives is increased on such pre-treated surfaces
The primer is only recommended for substrates that are difficult to bond, including polyethylene, polypropylene, polytetrafluoroethylene (PTFE) and thermoplastic rubber materials
LOCTITE SF 770 is not recommended in structures where high peel strength is required.

Precautionary statements

P210: Keep away from heat, hot surfaces, sparks, open flames and other ignition sources. No smoking.
P261: Avoid breathing dust/fume/gas/mist/vapours/spray.
P280: Wear protective gloves/protective clothing/eye protection/face protection.
P337 + P313: If eye irritation persists: Get medical advice/attention.
P403 + P235: Store in a well-ventilated place. Keep cool.

Hazard statements

H225: Highly flammable liquid and vapour.
H319: Causes serious eye irritation.
H336: May cause drowsiness or dizziness.

Supplemental hazard information

EUH066: Repeated exposure may cause skin dryness or cracking.

Frequently asked questions about this product

Answered by specialists

What is Loctite SF 770 used for?: This primer improves the adhesion of cyanoacrylate instant adhesives to difficult-to-bond plastics such as polyethylene (PE), polypropylene (PP), PTFE, and thermoplastic rubber.
How do you apply this primer?: Apply a thin layer to the low-energy plastic by brushing or dipping, and allow it to dry before applying the instant adhesive.
Is this primer suitable for all bonding assemblies?: It is designed for low-energy surfaces and is not recommended for assemblies requiring high peel strength.
Do you need to apply the primer to both mating surfaces?: No, when bonding a polyolefin to a more easily bonded material, apply the primer only to the polyolefin substrate.
How can you verify that the primer has been applied?: The liquid fluoresces under UV light (365 nm), allowing easy visual inspection of surface coverage.
