Permabond UV7141 is a dual-cure adhesive with UV and anaerobic curing mechanisms — developed for glass-metal bonding in shadow areas where UV light cannot reach the adhesive.

With ceramic-coated glass, backlit mirrors, or designs with overlapping adhesive surfaces, UV light cannot fully reach the adhesive — standard UV adhesives would not cure in shadow areas and would remain uncured.

UV7141 solves the problem with a dual curing mechanism: UV curing secures positioning in seconds — even without holding fixtures — and simultaneously anaerobic curing begins in shadow areas. After 24 hours, the bond is fully cured, with 14–17 N/mm² glass-to-steel strength.

SPECIAL FEATURE

Dual-Cure UV + Anaerobic — the unique combination of two curing mechanisms: UV light for visible bond lines, anaerobic for shadow areas where no UV light penetrates (e.g., behind ceramic-coated glass or in mirror bonding). Second-fast positioning + subsequent full curing.

Processing

1
Clean surfaces
Prepare bonding surfaces clean, dry, and free of grease — degrease with isopropanol or acetone. For aluminum/copper, lightly sand to remove the oxide layer. For plastics, check compatibility.
2
Apply adhesive thinly
Apply Permabond UV7141 thinly and evenly — directly from the bottle or via dispensing equipment. Keep adhesive protected from light. Avoid air entrapment.
3
Join and align components
Assemble quickly and precisely. For glass bonding, spread the adhesive into a thin film by applying pressure. Do not move components during UV curing.
4
Cure with UV light
Aim the UV lamp at the bond line. Curing time depends on lamp power, wavelength, and light transmission of the components — typically 1–5 seconds with a 30 W/cm² light guide system, or 5–15 seconds with a 4 mW/cm² low-power lamp.
5
Full strength after UV exposure
After complete UV curing, the components are immediately handleable. Final strength is achieved immediately after irradiation. For dual-cure products (UV + anaerobic), allow an additional 24 hours for complete anaerobic curing of shadow areas.

Important Notes

Not suitable for / Important notes
Store protected from light. Anaerobic curing requires metal contact in the bond gap.
Storage
Store at 5 to 25 °C and protect from direct light exposure. Curing begins under UV light — keep the bottle in the dark and only open under UV-blocked light.

Frequently asked questions about Permabond UV7141

Practical application and design questions — answered by SILITECH.

Permabond UV7141 is a methacrylic acid ester (UV + anaerobic) adhesive with a viscosity of 1,200–1,700 mPa·s @ 20 rpm. Dual-cure UV + anaerobic — also cures in shadow areas, for ceramic-coated glass and mirrors. The adhesive cures when exposed to UV light in the spectral range of 365–420 nm — rapid curing "on demand".

Permabond UV7141 cures in the spectral range of 365–420 nm. Suitable are standard UV lamps with mercury vapor, LED UV lamps with matching wavelength, or UV light guide systems. For LED lamps, the maximum wavelength of the LED must be matched to the curing spectrum of the adhesive — we are happy to advise you on the appropriate lamp selection.

The UV curing of Permabond UV7141 depends on lamp power, wavelength, and light transmission of the components. Typical curing times range from seconds to a few minutes.

Permabond UV7141 bonds reliably: glass/steel: 14–17 N/mm². For thermoplastic substrates, we recommend checking compatibility before series production — mold release agents on injection-molded parts can impair adhesion strength.

Permabond UV7141 is dual-cure UV + anaerobic (for shadow areas) (1,200–1,700 mPa·s @ 20 rpm viscosity, 20–50% elongation at break). Permabond UV6160 is optically clear thick (1,000–2,000 mPa·s, 100–150% elongation at break) — pure UV curing.

When stored at 5 to 25 °C and protected from light, Permabond UV7141 remains stable until the printed expiration date. IMPORTANT: UV adhesives cure upon exposure to light — always store the bottle in the dark and open it only briefly under UV-blocked light. For daylight-stable variants (e.g., UV675), processing under ambient light is possible for short periods.

From the Permabond UV series, choose according to substrate, viscosity, and special properties: Permabond UV7141 (Dual-cure UV + anaerobic (for shadow areas)); Permabond UV6160 (Optically clear thick); Permabond UV6231 (Outdoor weather); Permabond UV610 (High-strength glass furniture). For shadow areas (where UV light does not fully reach the bond line), a dual-cure variant such as Permabond UV7141 (UV + anaerobic) should be used.
