PERMABOND UV6260

Main features

  • Filtered-Light UV Curing
  • Tack-Free Surface Cure
  • High-Elongation Plastic Bonding

Product Description

Permabond UV6260 is a thixotropic, extremely fast UV-curable urethane acrylate adhesive for metals, glass, and rigid plastics when the substrate filters the curing light. The pale-yellow liquid cures colorless and tack-free across 365 to 420 nm. On glass, typical fixture time is below 1 second with a 395 nm, 150 mW/cm^2 LED and 6 seconds at 0.1 mW/cm^2, subject to lamp and substrate conditions. Cured data include overlap shear above 11 N/mm^2 on polycarbonate with substrate failure, 205% elongation, and 60 Shore D hardness.

Key features

  • Filtered-Light UV Cure: Cures across 365 to 420 nm for substrates that filter the curing light.
  • Tack-Free Surface Cure: Produces a tack-free surface after adequate UV exposure.
  • Rigid-Plastic Bond Strength: Provides substrate-failure shear results on polycarbonate, acrylic, PETG, and PVC-to-PC joints.

Applications

Applications include bonding colored glass, metals, polycarbonate, PMMA, PETG, PET, ABS, and rigid PVC where curing-light transmission is adequate.

Specific Gravity
Specific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume. For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless.

Physical Properties
Viscosity
Viscosity is a measurement of a fluid’s resistance to flow. Viscosity is commonly measured in centiPoise (cP). One cP is defined as the viscosity of water and all other viscosities are derived from this base. MPa is another common unit with a 1:1 conversion to cP. A product like honey would have a much higher viscosity -around 10,000 cPs- compared to water. As a result, honey would flow much slower out of a tipped glass than water would. The viscosity of a material can be decreased with an increase in temperature in order to better suit an application

Mechanical Properties
Elongation
Elongation is the process of lengthening something. It is a percentage that measures the initial, unstressed, length compared to the length of the material right before it breaks. It is commonly referred to as Ultimate Elongation or Tensile Elongation at break.

Electrical Properties
Dielectric Strength
Dielectric strength is measured in kV per mm and is calculated by the Breakdown voltage divided by the thickness of the tested material. Those two properties go hand in hand and while Breakdown voltage is always thickness dependent, dielectric strength is a general material property. As an example, the dielectric strength of Polyimide is 236 kV/mm. If we place 1mm of Polyimide between two electrodes, it will act as an insulator until the voltage between the electrodes reaches 236 kV. At this point it will start acting as a good conductor, causing sparks, potential punctures and current flow.
