Loctite SF7387 Activator

Loctite SF 7387 Dihydropyridine Activator

• Viscosity : Very low
• Color : Amber, Translucent, Yellow
• Curing Type : Not applicable
• Application : Cure promotion of toughened
  acrylic adhesives

 

LOCTITE SF 7387 is a yellow to amber, transparent liquid substituted dihydropyridine activator containing the solvents n-Heptane and isopropanol. It is designed for LOCTITE toughened adhesives to initiate the cure of acrylic adhesives.

• Designed for LOCTITE adhesives

LOCTITE® SF 7387™ is designed to initiate the cure of Loctite
toughened acrylic adhesives.

TYPICAL PERFORMANCE

Fixture time and cure speed achieved as a result of using
LOCTITE® SF 7387™ depend on the adhesive used, the
substrate bonded, surface cleanliness and whether one or two
surface activation is used.

Handling precautions

Activator must be handled in a manner applicable to highly
flammable materials and in compliance with relevant local
regulations.
The solvent can affect certain plastics or coatings. It is
recommended to check all surfaces for compatibility before
use.

GENERAL INFORMATION

This product is not recommended for use in pure oxygen
and/or oxygen rich systems and should not be selected
with a sealant for chlorine or other strong oxidizing
materials.
For safe handling information on this product, consult the
Safety Data Sheet (SDS).
Under no circumstances should activator and adhesive be
mixed directly as liquids. Use only in a well ventilated area.

Directions for use

1. Most surfaces may be bonded "as received" but
   contamination such as loose oxide layers or excessive oil
   may affect cure speed and bond strength. Cleaning is
   recommended if maximum strength is required.
2. Brush on the activator to one of the mating surfaces to be
   bonded. Apply adhesive to other surface.
3. For large gaps (>0.4 mm) or where maximum cure speed
   is required then treatment of both surfaces is
   recommended.
4. Allow 1 to 5 minutes for solvent to evaporate. After the
   solvent evaporates, the active ingredients will appear wet,
   and will remain active for up to 2 hours after application.
   Contamination of the surface before bonding should be
   prevented.
5. Where adhesive is applied onto an activated surface,
   assembly should be completed as quickly as possible
   (within 15 seconds).
6. Secure the assembly and await fixturing before any
   further handling.
