Permabond UV6160 is an optically clear UV-curing adhesive, specially developed for thick layers and compressive or highly stressed bonding applications — it remains crystal clear even under pressure and in thick gaps.
With a viscosity of 1,000–2,000 mPa·s, UV6160 is medium-viscosity. Its special formulation ensures that the adhesive retains its optical clarity even in thick adhesive gaps or under heavy loads—typical standard UV adhesives can easily become milky in thick layers.
The elongation at break of 100–150% and the tensile strength of 15–25 N/mm² (ISO37) make UV6160 the choice for demanding glass architecture and load-bearing bonding applications that require optical perfection.
Optically clear even in thick layers and under pressure or heavy loads — UV6160 was specially formulated to remain crystal clear even in thick adhesive gaps or compressive bonding. Improved resistance to sunlight yellowing.

Frequently asked questions about Permabond UV6160
Practical application and design questions — answered by SILITECH.
Permabond UV6160 is a methacrylate ester (UV-curing) adhesive with a viscosity of 1,000–2,000 mPa·s @ 20 rpm. This optically clear UV adhesive is suitable for thick layers and heavy loads, offering improved transparency. The adhesive cures upon exposure to UV light in the 365–400 nm spectral range, providing instant curing on demand.
Permabond UV6160 cures in the spectral range of 365–400 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 UV6160 typically cures in: <10 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 UV6160 bonds reliably to glass/steel: 11–18 N/mm² (depending on age). For thermoplastic substrates, we recommend testing compatibility before series production—release agents on injection-molded parts can impair adhesion.
Permabond UV6160 is an optically clear UV adhesive for thick layers and heavy loads (1,000–2,000 mPa·s @ 20 rpm viscosity, 100–150% elongation at break). Permabond UV6231 is a weather-resistant/outdoor adhesive (5,000–8,000 mPa·s, >120% elongation at break) — weather-resistant, high viscosity.
When stored at 5 to 25 °C and protected from light, Permabond UV6160 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 UV6160 (optically clear UV adhesive for thick layers and heavy loads); Permabond UV6231 (bathroom/outdoor weather); Permabond UV620 (optically clear); Permabond UV610 (high-strength glass furniture). In 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.
