Product Description

Permabond UV6302 is a low-viscosity, wicking-capable UV-curing adhesive specifically for polycarbonate bonding — the capillary action enables the subsequent bonding of already joined components.

With a viscosity of 75 mPa·s, UV6302 is very low and flows into micro-gaps between joined polycarbonate components via capillary action. It is the Wicking equivalent of UV630 — same curing chemistry 365–420 nm, but lower viscosity.

The excellent adhesion of the plastic leads to substrate failure on polycarbonate exceeding 7 N/mm². With an elongation at break of 100–150% and a tensile strength of 15–20 N/mm², the bond is both flexible and high-strength. A refractive index of 1.474 is close to that of glass—optically inconspicuous.

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 UV6302 thinly and evenly – directly from the bottle or using a dispensing device. Keep the adhesive protected from light. Avoid air bubbles.
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.

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 UV6302

Practical application and design questions — answered by SILITECH.

Permabond UV6302 is a methacrylate ester (UV-curing, long-wavelength) adhesive with a viscosity of 75 mPa·s. This low-viscosity polycarbonate UV adhesive is wicking-capable and suitable for tight-tolerance plastic fits. The adhesive cures upon exposure to UV light in the 365–420 nm spectral range, providing instantaneous curing "on demand".

Permabond UV6302 cures in the spectral range of 365–420 nm. Standard mercury vapor UV lamps, LED UV lamps with a suitable wavelength, or UV light guide systems are all suitable. 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 selecting the right lamp.

The UV curing of Permabond UV6302 depends on the lamp power, wavelength, and light transmittance of the components. Typical curing times range from seconds to a few minutes.

Permabond UV6302 reliably bonds: Polycarbonate: >7 N/mm² (substrate failure); PVC: >2 N/mm²; PMMA: 1.5–2 N/mm². For thermoplastic substrates, we recommend testing compatibility before series production — release agents on injection-molded parts can impair adhesion.

Permabond UV6302 is a polycarbonate wicking UV adhesive (low viscosity) (75 mPa·s viscosity, 100–150% elongation at break). Permabond UV630 is a standard low viscosity adhesive (250 mPa·s, 110% elongation at break) — higher viscosity, biocompatible.

When stored at 5 to 25 °C and protected from light, Permabond UV6302 is stable until the printed expiration date. IMPORTANT: UV adhesives cure upon contact with light — always store the bottle in the dark and only open it briefly under UV-blocked light. Daylight-stable variants (e.g., UV675) can be used briefly under ambient light.

From the Permabond UV range, select according to substrate, viscosity, and special properties: Permabond UV6302 (polycarbonate wicking UV adhesive (low viscosity)); Permabond UV630 (standard low viscosity); Permabond UV640 (standard medium viscosity); Permabond UV632 (urethane low viscosity). For shaded areas (where UV light does not fully reach the adhesive gap), a dual-cure variant such as Permabond UV7141 (UV + anaerobic) should be used.
