4. Nastavení a příprava

4.1 Příprava povrchu

For optimal adhesion, surfaces must be clean, dry, and free from oil, grease, dust, and other contaminants. Abrading surfaces with sandpaper or a wire brush, followed by a solvent wipe (e.g., isopropyl alcohol), can improve bond strength. Ensure surfaces are completely dry before adhesive application.

4.2 Dispensing and Mixing

Loctite 9460 is supplied in a dual cartridge system. It requires a specialized dispensing gun and static mixing nozzle for proper application. These accessories are typically sold separately.

1. Attach a static mixing nozzle to the dual cartridge.
2. Insert the cartridge into the appropriate dispensing gun.
3. Dispense a small amount of adhesive (approximately 1-2 inches) onto a disposable surface to ensure both components are flowing evenly and properly mixed through the nozzle. Discard this initial bead.

4.3 Podmínky prostředí

Apply the adhesive at room temperature (68-77°F / 20-25°C) for best results. Lower temperatures will increase cure time, while higher temperatures will decrease it.

5. Návod k obsluze (aplikace)

Once the cartridge is prepared with a mixing nozzle and dispensing gun, apply the mixed adhesive directly to one of the prepared surfaces. The working time (application time) for Loctite 9460 is approximately 50 minutes at room temperature.

• Apply a sufficient amount of adhesive to cover the bonding area.
• Bring the two surfaces together within the 50-minute application time.
• Ensure proper alignment and apply light clamping pressure if necessary to maintain contact during the initial cure phase. Avoid excessive pressure that could squeeze out too much adhesive.
• The non-sag property of this adhesive helps maintain its position on vertical or overhead surfaces during application.

6. Curing and Post-Application

Loctite 9460 achieves handling strength within a few hours, but a full cure typically takes 24 hours at room temperature (68-77°F / 20-25°C).

• Do not disturb or stress the bonded assembly during the curing period.
• Allow the full 24 hours for the adhesive to reach its maximum strength and chemical resistance.
• The cured adhesive can withstand temperatures up to 250°F (121°C).

7. Údržba a skladování

7.1 Skladování

Store unused Loctite 9460 cartridges in a cool, dry place, ideally between 46°F and 82°F (8°C and 28°C), away from direct sunlight and heat sources. Ensure the cartridge is sealed properly to prevent contamination and premature curing of the components.

7.2 Čištění

Clean tools and equipment with a suitable solvent (e.g., acetone or isopropyl alcohol) immediately after use, before the adhesive cures. Cured epoxy is very difficult to remove and may require mechanical abrasion.

8. Řešení problémů

• Špatná přilnavost: Ensure surfaces were properly cleaned and prepared. Verify that the adhesive components were thoroughly mixed (if not using a static mixer, or if the initial bead was not purged).
• Slow or Incomplete Cure: Check ambient temperature; lower temperatures significantly extend cure times. Ensure proper mixing ratio if not using a static mixer.
• Adhesive Sagging: While Loctite 9460 is non-sag, excessive application thickness or very high temperatures during cure could potentially affect its thixotropic properties.

If issues persist, review the instructions carefully or contact Loctite technical support for assistance.
