Toughened, UV curable adhesive features optical clarity
Master Bond UV15-7HP is a low viscosity, easy to apply, one-part, UV curable adhesive system. 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 -80degF to 300degF. It is available in various packaging options: 10cc and 30cc syringes, 1/2 pints, pints, quarts, gallons, and 5-gallon containers.
