The success of a retained assembly hinges on the compound’s ability to completely fill the space between two mating surfaces. If your assembly has poor tolerances, is worn, or has larger-than-expected misalignments, using a thin, low-viscosity retaining compound designed for tight gaps simply won’t work. The compound may run out or sag, leaving voids that lead to movement, noise, and eventual bond failure.
The key to a secure fit in these challenging assemblies is selecting a compound with superior gap-filling capacity and high viscosity.
The Solution: High Viscosity for Maximum Gap Fill
To ensure a complete and solid cure in assemblies with larger diametral clearances, you need an anaerobic adhesive that is thick enough to stay put and designed to cure robustly in wider gaps.
Incure WeldLock™ 330 Green Retaining Compound
For hobbyists, DIYers, or industrial users dealing with worn components, loose tolerances, or larger gaps that thinner compounds can’t handle, we recommend the Incure WeldLock™ 330 Green Retaining Compound.
This ultra-high-strength compound is specifically engineered with the properties needed to excel in large-gap assemblies,providing a permanent structural lock.
| Key Feature | Benefit for Large Gaps and Misalignment |
| Superior Gap Fill Capacity | Handles the largest diametral gaps in the line, up to 0.26mm. This ensures complete void fill even in badly worn or misaligned components. |
| High Viscosity (2500 MPa⋅s) | This thick formulation resists running and sagging, guaranteeing the compound remains in the joint area to form a dense, uniform cure across the entire clearance. |
| Exceptional Strength (25 N/mm2) | Provides the highest level of structural strength, which is essential to secure parts that inherently lack good mechanical fit. |
| Fast Fixture Time (5 minutes) | Quickly locks the parts, preventing slippage or misalignment while the compound is curing in the larger gap. |
WeldLock™ 330 is the professional choice for salvaging worn machinery and securing parts where a precision fit is no longer possible, turning a loose assembly into a permanent, structural one.
Techniques for Success in Large-Gap Assemblies
When using WeldLock™ 330 for large clearances, application technique is vital to ensure maximum performance:
- Dual Surface Application: Don’t rely on just one surface. Apply a continuous bead of the high-viscosity compound to both the inner circumference of the female housing and the outer circumference of the male shaft/component. This guarantees maximum compound volume fills the large gap as the parts are assembled.
- Avoid Excessive Speeds: When pressing components together, do so steadily. Rapid assembly can push the thick compound out of the large gaps. A controlled press ensures the adhesive fully distributes.
- Allow Full Cure: The compound needs the full 24 hours at room temperature to achieve its maximum 25 N/mm2strength. This is crucial for load-bearing assemblies with wide gaps. Do not subject the assembly to shock or high load before the final cure is complete.
