Loctite SF 7649 Anaerobic Activator

Product overview

LOCTITE SF 7649 is a solvent-based activator for surface preparation that provides for low temperature curing.

LOCTITE SF 7649 is designed to promote the curing speed of LOCTITE anaerobic adhesives and sealants without any significant loss of joint strength. It is especially recommended for applications with passive metals or inert surfaces and with large bond gaps. LOCTITE SF 7649 offers good performance at low cure temperatures, and is recommended when the application temperature is below 15°C

FEATURED PROPERTIES

• Increases cure speed on passive and inactive surfaces
• For low-temperature curing (< 5°C)
• For large bond gaps

Directions for use:

1. Spray or brush on the activator on both mating surfaces to be bonded. For small gaps, treatment of only one surface may be adequate. Contaminated surfaces may need repeated treatment or special degreasing prior to activation to remove any dissolvable contamination. Porous surfaces may need two treatments of activator.

2. Allow the solvent time to evaporate under good ventilation until the surfaces are completely dry.

3. After activation, parts should be bonded within 1- month. Contamination of the surface before bonding should be prevented.

4. Apply the Loctite Anaerobic product to one or both surfaces and assemble parts immediately.

5. Where possible, move surfaces in relation to each other for a few seconds on assembly to properly distribute the adhesive and for maximum activation..

6. Secure the assembly and await fixturing before any further handling.
