LOCTITE SF7090
Harmonization Code : 3208.20.90 | Paints and varnishes that are dispersed or dissolved in a non aqueous medium

Main features
- Accelerates Cure of Loctite Anaerobic Adhesives
- Solvent-Free Bonding Formulation
- Passive Metals and Inert Materials
Product Description
LOCTITE® SF 7090™ is a reactive monomer-based, solvent-free surface activator designed to accelerate the cure speed of LOCTITE® anaerobic adhesives and sealants. It is particularly effective for use on passive metals, inert surfaces, large bond gaps, and low-temperature applications below 15°C. The activator promotes rapid fixture and cure development while remaining active on treated surfaces for up to one hour after application.
Key Features & Benefits
- Accelerates cure of LOCTITE® anaerobic adhesives and sealants.
- Solvent-free reactive monomer formulation.
- Ideal for passive metals and inert substrates.
- Improves curing across large bond gaps.
- Recommended for low-temperature applications (<15°C).
- Can be applied by spray or brush.
- Remains active on surfaces for up to one hour.
Recommended Applications
- Acceleration of anaerobic threadlockers.
- Acceleration of anaerobic retaining compounds.
- Passive metal assemblies.
- Large bond gap assemblies.
- Low-temperature bonding operations.
