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.
Low-viscosity wicking UV adhesive for polycarbonate bonding — the capillary action allows subsequent bonding of already joined plastic components with tightly toleranced fits.

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.
