Permabond UV630 is a UV-curing adhesive specifically for plastics — biocompatible according to ISO 10993-5 (cytotoxicity passed) and with long-wave curing 365–420 nm, which also bonds UV-stabilized substrates.
With a viscosity of 250 mPa·s, UV630 is low-viscosity and fills standard plastic gaps. Curing under long-wave UV light (365–420 nm) is key for processing UV-stabilized plastics — many modern plastic components are protected against short-wave UV, and standard UV adhesives (320–400 nm) do not cure under these conditions.
The ISO 10993-5 cytotoxicity test qualifies UV630 for medical and hygiene-related applications—such as medical devices with plastic components, pharmaceutical packaging, or laboratory equipment. The adhesive cures colorless and is optically invisible.
Biocompatible according to ISO 10993-5 + curing under long-wave UV light — qualified for medical and hygienic plastic bonding (polycarbonate, acrylic). The long-wave curing allows the bonding of UV-stabilized plastics.

Frequently asked questions about Permabond UV630
Practical application and design questions — answered by SILITECH.
Permabond UV630 is a methacrylic acid ester (UV-curing, long-wavelength) adhesive with a viscosity of 250 mPa·s @ 20 rpm. This UV adhesive for plastics is biocompatible (ISO 10993-5) and low-viscosity for polycarbonate. The adhesive cures upon irradiation with UV light in the spectral range of 365–420 nm, providing instant curing on demand.
Permabond UV630 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.
Permabond UV630 typically cures in: 5 s with a 4 mW/cm² low-power lamp; 2 s with a 100 mW/cm² LED lamp; 1 s with a 30 W/cm² UV light guide system. The exact curing time depends on the layer thickness and the light transmittance of the components.
Permabond UV630 bonds reliably to: Polycarbonate: >9 N/mm² (substrate failure); Acrylic: >1.5 N/mm². For thermoplastic substrates, we recommend testing compatibility before series production — release agents on injection-molded parts can impair adhesion.
Permabond UV630 is a UV adhesive for plastics — biocompatible (250 mPa·s @ 20 rpm viscosity, 110% elongation at break). Permabond UV640 is a high-viscosity plastic adhesive (3,000–5,000 mPa·s, 110% elongation at break) — a higher viscosity variant of UV630.
When stored at 5 to 25 °C and protected from light, Permabond UV630 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 UV630 (UV adhesive for plastics — biocompatible); Permabond UV640 (high-viscosity plastics); Permabond UV645 (gap-filling plastics); Permabond UV632 (urethane methacrylate). For shadowed areas (where UV light does not fully reach the adhesive gap), a dual-cure variant such as Permabond UV7141 (UV + anaerobic) should be used.
