Permabond UV006320001L0101, UV632 UV-Curable Adhesive, 1 Liter Bottle
Permabond UV006320001L0101, UV632 UV-Curable Adhesive, 1 Liter Bottle
Permabond UV632 is a single-part urethane methacrylate adhesive developed for plastic bonding, with excellent adhesion to acrylic. Its long-wavelength photoinitiator allows cure through suitable UV-stabilized plastics, subject to the actual substrate's light transmission and the curing setup. UV632 can also bond glass, metals and other materials, and produces a colorless bond for appearance-sensitive assemblies. SKU UV006320001L0101 supplies one 1-liter bottle, sold individually.
Best Uses / Applications
- Acrylic bonding where bond-line appearance matters.
- UV-stabilized plastic assemblies after confirming light transmission and cure through the actual part.
- Clear plastic and mixed-material assemblies with light access to the bond line.
- Appearance-sensitive display and decorative assemblies, subject to joint testing.
- Production dispensing from a 1-liter bottle using compatible equipment protected from ambient light.
Key Features
- Cure on demand without resin/hardener mixing.
- Low viscosity: 200–400 cP at 25°C and 20 rpm.
- Long-wavelength photoinitiator for suitable UV-stabilized plastics.
- Clear, colorless appearance and colorless cured bond.
- 100% solids, solvent-free formulation.
- TDS fixture-time examples include low-power, LED and light-guide sources.

These are typical manufacturer data, not guaranteed assembly specifications. Fixture times are not full-cure schedules. Cure depends on lamp power, spectral output, lamp distance, substrate transmission and bond-line conditions. Qualify full cure using the actual assembly and equipment.

The 2021 family brochure is a screening guide, not a substitute for each grade's TDS. Its UV632 polycarbonate shear figure differs from the supplied grade-specific TDS; the specifications above use the TDS value of >7 N/mm², with substrate failure. Confirm any design-critical value with Permabond before qualification. Similar appearance or chemistry does not establish interchangeability.
Surface Preparation & Application
- Use clean, dry, grease-free surfaces. Remove silicone-based cleaning residues from glass.
- Check thermoplastic compatibility and mold-release contamination. The TDS identifies isopropanol for degreasing most surfaces; evaluate the actual substrate.
- Some metals, including aluminum and copper alloys, benefit from light abrasion to remove oxide.
- Dispense directly or through compatible automated equipment while minimizing ambient-light exposure.
- Avoid entrapping air, hold parts firmly and do not disturb them during cure.
- Expose the joint for the qualified full-cure schedule using a matched lamp. Confirm light transmission through the actual substrate.
Do not assume every UV-blocking plastic transmits enough suitable light or that shadowed adhesive will cure. The supplied UV632 TDS does not establish a secondary shadow-cure mechanism. The product is not recommended for contact with strong oxidizing materials. Follow the SDS and curing-equipment safety instructions.

Frequently Asked Questions
What does this listing include?
One 1-liter bottle of Permabond UV632, SKU UV006320001L0101, sold individually.
Can UV632 cure through UV-stabilized plastic?
Its long-wavelength photoinitiator is intended to enable that capability. Actual cure still depends on the plastic's transmission, thickness and lamp setup. Test the real assembly rather than assuming compatibility with every UV-blocking material.
What wavelength does UV632 require?
The TDS lists 365–420 nm. Because LED lamps have narrow spectral output, Permabond recommends confirming the lamp's peak wavelength matches the adhesive.
Does a four-second fixture time mean full cure?
No. Four seconds is the TDS's typical acrylic fixture-time example with a 100 mW/cm² LED lamp. Establish the full-cure exposure for your actual source, distance, substrates and joint.
Is it suitable for acrylic and appearance-sensitive assemblies?
The TDS identifies excellent acrylic adhesion and a colorless bond. Validate optical appearance, aging and mechanical performance in the intended service conditions; this is not a blanket no-yellowing guarantee.
How does UV632 compare with UV640?
The family guide positions UV632 as a low-viscosity plastic-bonding grade with excellent acrylic adhesion. UV640 is a medium-viscosity plastic-bonding grade. Select using the grade-specific TDS and actual dispensing and joint requirements.
Can UV632 cure in shadowed joints?
Do not assume so. The supplied TDS does not identify a secondary shadow-cure mechanism. Ensure suitable light reaches the adhesive or evaluate another formulation with manufacturer guidance.
How should UV632 be stored and dispensed?
Store at 5–25°C and protect the liquid adhesive from room lighting. Minimize ambient-light exposure during dispensing, avoid air entrapment and keep parts fixed during cure.
