Permabond UV645 50 ml is the small container variant of the high-viscosity plastic UV adhesive UV645 — same technical specification, ideal for small quantity consumption.
The 50 ml version offers the same high-viscosity UV adhesive specification as the standard container. Ideal for workshops, service calls, or small production runs where large volumes are not efficient to use.
With 8,000–10,000 mPa·s and long-wave curing 365–420 nm, UV645 reliably bonds polycarbonate, PVC and PC/ABS mixtures — even in vertical applications.
50 ml small container of the plastic UV adhesive UV645 — same specification as the standard version, ideal for small series production, repair and service applications.

Frequently asked questions about Permabond UV645 (50 ml)
Practical application and design questions — answered by SILITECH.
Permabond UV645 50 ml is a methacrylic acid ester (UV-curing, long-wave) adhesive with a viscosity of 8,000–10,000 mPa·s @ 20 rpm / 30,000–60,000 mPa·s @ 2.5 rpm. Permabond UV645 in the 50 ml version has the same specifications as the standard container. The adhesive cures upon irradiation with UV light in the spectral range of 365–420 nm—curing in seconds, "on demand".
Permabond UV645 50 ml 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 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 time of Permabond UV645 50 ml depends on the lamp power, wavelength, and light transmittance of the components. Typical curing times range from seconds to a few minutes.
Permabond UV645 50 ml reliably bonds: Polycarbonate: >9 N/mm² (substrate failure); PVC: >5 N/mm². For thermoplastic substrates, we recommend testing compatibility before series production — release agents on injection-molded parts can impair adhesion.
Permabond UV645 50 ml is a UV adhesive for plastics (high viscosity, 50 ml container) (8,000–10,000 mPa·s @ 20 rpm / 30,000–60,000 mPa·s @ 2.5 rpm viscosity, >70% elongation at break). Permabond UV645 is a standard container (8,000–10,000 mPa·s, >70% elongation at break) — standard packaging.
When stored at 5 to 25 °C and protected from light, Permabond UV645 50 ml 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 UV645 50 ml (UV adhesive for plastics (high viscosity, 50 ml container)); Permabond UV645 (standard container); Permabond UV649 (plastic gel); Permabond UV640 (medium viscosity plastic). 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.
