Application Guidance
Surfaces should be clean, dry, and free of grease, dust, oils, and other contaminants before bonding. Apply UV3660 MV to the trim cap bonding area, position the components, and expose the joint to suitable UV light. Cure speed depends on lamp intensity, wavelength, distance from the bond area, bond-line thickness, and UV transmission through the substrates.
Typical Use Cases
- Trim cap bonding for channel letters
- Polycarbonate trim cap to acrylic face bonding
- PVC trim cap to acrylic face bonding
- Illuminated sign fabrication
- Dimensional letter assembly
- Commercial and architectural signage
Target Industries and Buyers
- Sign manufacturers
- Channel letter fabricators
- Commercial sign shops
- Architectural signage companies
- OEM sign producers
- Display and graphics manufacturers
Performance Advantages
Chem-Set™ TrimLok™ UV3660 MV gives sign fabricators a clear, UV-curable bonding option for trim cap assembly where fast fixturing, precise placement, and clean bond appearance are important. Compared with slower or less controlled bonding methods, its single-component UV cure helps streamline production while supporting accurate alignment before cure.
Common Questions
Q: What is UV3660 MV used for?
A: UV3660 MV is used for trim cap bonding in sign fabrication, especially bonding polycarbonate or PVC trim cap to acrylic sign faces.
Q: Does UV3660 MV require mixing?
A: No. It is a single-component UV-curable adhesive.
Q: How does UV3660 MV cure?
A: It cures when exposed to appropriate UV light.
Q: Is the bond line clear?
A: Yes. UV3660 MV is intended for clear bonding applications where appearance matters.
Q: Can it be used for channel letter fabrication?
A: Yes. It is designed for trim cap bonding applications commonly used in channel letters and illuminated signage.
Q: Why use a medium-viscosity adhesive for trim cap bonding?
A: Medium viscosity helps control adhesive placement in narrow bonding areas while reducing excessive flow.
Q: What affects UV cure speed?
A: Cure speed depends on UV lamp intensity, wavelength, distance from the joint, bond-line thickness, and substrate UV transmission.
