Application:

1. Apply the Loctite 660:

   • Apply the adhesive evenly to one of the parts (usually the shaft or the bearing). A small amount is sufficient, as Loctite 660 spreads well during the assembly.

   • Use a brush, squeeze bottle, or applicator tip for more precision.

2. Assemble the Parts:

   • Quickly position the parts together. Since Loctite 660 is a fast-setting adhesive, alignment should happen quickly after applying the adhesive.

   • Press the parts together firmly to ensure a good bond. If you are using it for a bearing or shaft, align the parts properly and fit them securely.

3. Secure the Assembly:

   • Hold the parts in place or secure them with clamps, bolts, or a fixture if necessary.

   • The adhesive will begin to cure at room temperature, but applying slight pressure can help eliminate air gaps and ensure a stronger bond.

Basic Tips:

• Temperature Range: Loctite 660 works best within a temperature range of -55°C to 150°C (-67°F to 302°F). It’s resistant to oils, fuels, solvents, and water.

• Storage: Store Loctite 660 in a cool, dry place, and keep the bottle tightly closed when not in use to maintain the adhesive's effectiveness.

• Cleanup: If you need to clean up excess adhesive before it cures, use a solvent or acetone, but do so quickly. Once the adhesive starts curing, it becomes very difficult to remove.

• Safety: Always use Loctite 660 in a well-ventilated area, and avoid direct skin contact. Wear gloves and eye protection, and refer to the product's safety data sheet (SDS) for more safety guidelines.
