UV25 one-component UV curable material is for bonding, sealing, coating and encapsulation applications. Has a glass transition temp. of 186°C. Is serviceable between -60° and +500°F. Is optically clear with a refractive index of 1.55 at room temp. On exposure to a UV light source emitting at a wavelength of 320-365nm with an energy output of 20 to 40mW per cm², it cures in 20 to 30 sec. Contains no solvents or volatiles; features low shrinkage upon curing. Bonds well to glass, surface treated metals and plastics such as polycarbonates and acrylics. When used in potting applications, it can cure in section up to 0.100-0.120". At room temperature, it has a viscosity of 7,000-11,000cps.
