UV curing adhesive passes NASA low outgassing specifications 09 September 2019

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 - 140°C and is serviceable from -60°F to +450°F. Its hardness upon curing is 75 - 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 - 30 seconds when exposed to a UV light source emitting at a wavelength of 320Nm – 365Nm with 20 - 40 milliwatts per cm2.

UV10TK40M bonds well to glass, surface treated metals and plastics such as polycarbonates and acrylics. UV10TK40M is recommended in fibre optic, optical, opto-electronic and electronic applications where heat resistance and a moderate viscosity are needed. The product is available in ½ pints, pints, quarts, gallons and syringes.
