Main features

  • Fast UV/Visible-Light Plastic Bonding
  • Moisture-Resistant Clear Bond Lines
  • Fluorescent In-Line Inspection

Product Description

Dymax Ultra Light-Weld 3019 Series Moisture-Resistant Adhesives are UV- and visible-light-curable adhesives for fast bonding of flexible and rigid plastic substrates. The 100% reactive-solids, solvent-free formulations form clear bond lines on materials including polycarbonate, PVC, polyurethane, PET, PETG, polystyrene, and nylon. The series includes a nominal 450 mPa s 3019 liquid and a 25,000 mPa s 3019-GEL grade for different dispensing requirements. After cure, typical series properties include Shore D55 hardness, 1,700 psi tensile strength, and 170% elongation at break. The adhesives also fluoresce under low-intensity 365 nm black light, supporting in-line inspection of dispensed and bonded areas.

Key features

  • Fast light-activated bonding: UV or visible light develops bonds in seconds under validated exposure conditions.
  • Liquid and gel viscosities: The series includes nominal 450 mPa s and 25,000 mPa s grades for different dispensing needs.
  • Fluorescent inspection: The adhesive fluoresces under low-intensity 365 nm black light.

Applications / Suitable for

  • Polycarbonate and PVC bonding
  • Polyurethane, PET, and PETG bonding
  • Polystyrene and nylon bonding

Refractive index
The refractive index determines how much the path of light is bent, or refracted, when entering a material. It is calculated by taking into account the velocity of light in vacuum compared to the velocity of light in the material. The refractive index calculation can be affected by the wavelength of light and the temperature of the material. Even though it is usually reported on standard wavelengths it is advised to check the TDS for the precise test parameters.

Thermal Properties
Flash Point
The flashpoint of a solvent is the lowest possible temperature at which it can vaporize to form an ignitable vapor. Flashpoint is often confused with “autoignition temperature”, which is the temperature at which a solvent ignites without an ignition source.
