The instinct to use “a little extra” adhesive often backfires with retaining compounds. Over-application doesn’t increase strength; instead, it creates a messy job, wastes product, and, critically, can interfere with the proper seating and functionality of precision components like bearings.
The problem isn’t the strength of the compound, but rather its viscosity and how much you apply. A low-viscosity (thinner) compound is more likely to run and squeeze out excessively, while any compound applied too liberally can cause issues.
The Solution: Controlled Application with Optimal Viscosity
To ensure a clean, precise fit and avoid messy squeeze-out, you need a compound with a medium viscosity that provides good flow for gap filling but remains controllable enough for accurate application.
Incure WeldLock™ 365 Green Retaining Compound
For hobbyists, DIYers, or industrial users seeking a balance of high performance and controlled application to prevent excess squeeze-out, we recommend the Incure WeldLock™ 365 Green Retaining Compound.
This product is a high-strength compound with a medium viscosity, making it ideal for precision assemblies where controlled application is necessary, such as fitting bearings, shafts, and bushings with minimal clearance.
| Key Feature | Benefit for Controlled Application |
| Medium Viscosity (1250 MPa⋅s) | Thicker than watery compounds, allowing for controlled, precise application with less dripping and excess run-out. |
| High Strength Bond | Provides the reliable, durable bond needed for slip-fit and worn assemblies without needing excessive product. |
| Moderate Gap Fill | Handles gaps up to 0.25mm. This capacity ensures a solid lock without demanding vast amounts of compound to fill large voids. |
| Fast Fixturing | Sets in just 10 minutes, quickly securing the part before any minimal excess can flow into unintended areas. |
WeldLock™ 365 delivers powerful retention while offering better control than super-thin compounds, making it a professional’s choice for clean, high-precision assembly work.
How to Apply Retaining Compound Like a Pro (No Mess Allowed)
Follow these steps with WeldLock™ 365 to ensure a clean application with optimal performance and minimal squeeze-out:
- Preparation is Key: As always, ensure both mating surfaces are thoroughly cleaned and degreased.
- The Single Bead Rule: Do not drench the part. For press-fit or slip-fit assemblies, apply a single, thin, continuous bead of compound only to the male component (the shaft or bearing outer race) near the leading edge. The mating process will distribute the compound evenly into the clearance.
- Wicking Action: For blind holes or assemblies with tighter tolerances, you can apply a smaller amount just inside the mouth of the female component (the housing). The low-anaerobic liquid will wick (flow) into the gap as the parts are pressed together.
- Wipe the Excess: Due to the controlled nature of WeldLock™ 365’s medium viscosity, any minimal squeeze-out that occurs will be easy to manage. Use a clean, lint-free cloth or swab to wipe away the uncured excess immediately after assembly. This prevents it from curing outside the joint and ensures a professional finish.
