One-part, UV curable bond
Master Bond UV10TK40M is a one-part UV curable system, which is not oxygen inhibited, and can be used for bonding, sealing and coating applications. UV10TK40M is optically clear, with a refractive index of 1.55. It has a high glass transition temperature (Tg) of 135°C to 140°C and is serviceable from -60°F to 450°F. Its hardness upon curing is 75 Shore D to 85 Shore D.
“Not only does it meet NASA low outgassing specifications, but this system also withstands 1,000 hours at 85°C/85% RH. Its Shore D hardness was not adversely affected even after exposure to elevated temperatures and high relative humidity,” says Rohit Ramnath, Senior Product Engineer. UV10TK40M cures in 20 to 30 seconds when exposed to a UV light source emitting at a wavelength of 320nm to 365nm with 20mW/cm² to 40mW/cm².
UV10TK40M bonds well to glass, surface treated metals, and plastics such as polycarbonates and acrylics. UV10TK40M is recommended in fiber-optic, optical, opto-electronic and electronic applications where heat resistance and a moderate viscosity are needed. The product is available in 1/2 pints, pints, quarts, gallons, and syringes.
