Toughened, UV Curable Adhesive Features Optical Clarity

April 22, 2025
Master Bond formulates high-quality, innovative compounds for the laser, optics, and photonics industries. Our goal is to help engineers meet specific requirements for their bonding, sealing, and coating applications.

Optimal adhesion is achieved in bond line thicknesses of 0.001-0.003 inch, and it can cure rapidly with a minimum intensity of 20-40 milliwatts/cm2 using a UV light source emitting at a wavelength of 320-365 nm. The material can also be cured in sections up to 0.125 inch thick under appropriate conditions, making it suitable for bonding, sealing, coating, and encapsulation.

UV15-7HP has a strong performance profile, featuring a tensile strength of 6,000-7,000 psi and a tensile modulus of 250,000-300,000 psi at room temperature. This toughened system resists thermal cycling and offers significant elongation of 5-10%. It is an electrically insulative material with a volume resistivity greater than 1014 ohm-cm. Optically clear with a refractive index of 1.54 at 589 nm, it is not oxygen inhibited and contains no solvents or diluents.

UV15-7HP bonds well to a wide variety of substrates including glass, ceramics, metals and many plastics, such as polycarbonates, acrylics and polyester films. This system is serviceable in a wide range of temperatures from -80°F to 300°F. It is available in various packaging options: 10cc and 30cc syringes, ½ pints, pints, quarts, gallons, and 5-gallon containers.
